This ad is aimed at the DIY student or hobbyist who is working on his/her own electronic device and needs assistance in troubleshooting.


Consumer-level meters simply do not have the ability to thoroughly test solid state electronics. For example the average multimeter can only test Volts and Ohms.


Intermediate level meters can check capacitance but not ESR. These intermediate level meters can test transistor gain but not leakage. This leads to frustration in the student or DIY repairman/woman because they are looking for a fault they cannot find.


I have professional test equipment which can thoroughly test components you send me for test. Most components on a PCB are soldered in place. You must carefully desolder components before sending them for test. 


Identification of Unmarked components

1. Scratched off markings

2. Worn ratings number

3. IC chips


I am looking for a  "U-TEST-M" vacuum tube tester made by Colonial Merchandising model 2500 and when I purchase one - I will update this ad to include vacuum tube testing service also.


I am looking for a "Linear IC Tester" or "Universal IC Tester" and when I purchase one or more I will add this to my list of chips.


There are many parts I have in stock as replacements and some that I do not have in stock. I also have many books which show the ratings of thousands of parts. I can also cross reference substitutes and replacement parts.


I can identify a replacement/substitute for most parts.

Tips

1. Always put your IC chips in sockets when building a kit

2. If your device runs on batteries - dont run off power adapter

3. Use a correct soldering iron 15watts or less

4. Learn to desolder quickly without overheating your parts.

5. Take a detailed photograph of your PCB and make notes and sketches before desoldering anything from the board.

6. Don't tinker - do it the right way - or don't do it at all


Contact me if you need chips or other electronic components tested. I try to be reasonably priced. Many electronic devices made in the 1970s, 1980s, 1990s, 2000s, 2010s used off-the-shelf stock chips for all or a portion of their functions. I can test these industry-standard parts.


What I'm trying to say is - when you are repairing a device - finding the 1 bad component - whether it is an IC chip or other - you hope that it will be a common part that failed - one that you can easily replace and is readily available. Most likely your device has failed in one or more common parts - cheap to replace - but the trouble is - in identifying which one has failed.


The number one cause of failures in electronic devices is electrolytic capacitors (sometimes obvious due to the bulge) and sometimes tantalum capacitors will spontaneously cease to function or pop/explode - as these can fail quickly - sometimes while letting out a very foul smell unique to a dying tantalum capacitor (several aerospace companies refuse to use tantalum caps in their space missions)


I can test capacitors with my professional ESR tester. Bad capacitors do not always bulge. Sometimes electrolytic capacitors will make a loud POP like a firecracker as it is dead - bulging the top or not bulging the top. Most failures are not dramatic and make no noise or smoke or smell. Equipment is necessary to identify these bad components without visible clues - which is where my expertise comes in.

The above is a ESR tester - EDS-88A CapAnalyzer which tests ESR (equivalent Series Resistance) for electrolytic capacitors and other types such as tantalum and more. The above file is the user manual. My ESR meter is the EDS-88A which is a slightly more recent design. The LED bargraph display is easy to read and the alarm sound is settable by the linear potentiometer for sensitivity. The best feature is its automatic self-discharge of capacitors. That was its biggest selling point to me and a big time saver. It will cycle through self-test and several other checks before each and every capacitor check. It is a quick machine and has found countless bad capacitors. An excellent ESR tester.

I already know where the bar graph LEDs should be for small through large capacitors so I dont need to refer to the chart anymore. I just know when the bargraph looks odd for a capacitor then I know it is time to change it. Also comparing the same size capacitor over the same to-be-repaired-board  will make a few stand out as being weak or odd functioning. It is a true in-circuit tester. Some bad capacitors show a led toards the bottom of the bar-graph or dont register at all. Slightly weak capacitors can be just a little higher or lower than should be- those are generally not the cause of a failure in equipment operating. It is the capacitors which deviate drastically that generally are the cause of equipment failure to function etc. I always check my new parts too because there are sometimes duds in brand new capacitors purchased in bulk.

Finding a bad capacitor is not about nit-picking if it is in the red or yellow or green area of the chart. A bad capacitor will be blatently bad. If it is not blatently bad then most likely - that capacitor is not causing your equipment to have failed to work.

A bad capacitor will usually be 2x or 3x or more - the rated esr of the rest of the caps you test which are of similar size/type. It will be blatently bad or will give a no reading or a alarm or be drastically different than the rest of the caps.

Cracked or bulged caps or caps which leak gunk (flux) or fluid (flux) are definitely bad and should be replaced- even if they test fine. Some capacitors are glued by the factory - dont mistake glue for leaking flux.

I dont recommend powering up the tester with the red button held down- this disables the self discharge feature (until next power off) because self-discharge is a protection for your esr tester. Touching a charged capacitor can kill the esr tester. Even though it takes an extra second to automatically discharge.

The tester needs no polarity as it functions with self-generated AC frequency and AC is non-polarized. What that means is that you can test an electrolytic capacitor either-way -either polarity of the black/red lead is fine and doesnt matter to the tester which way you connect it to the polarized cap.

It is important not to test huge capacitors with this tester. Just normal size or small capacitors as found in everyday electronic devices like TV radio computers and other ordinary household type equipment. It is not for big high-powered capacitors.

Capacitors generally have a 2000 hour lifespan. It is a wonder most electronics lasts longer than 90days because that is the warranty period. Capacitor's 2000 hour life is 90days. It is a wonder that devices like tv sets last longer than 90days. I always shut off my equipment and appliances and audio/visual gear & more when not in use. Why waste the life of your equipment - by just letting it run idle?

Runs on 1ea 9V battery. Purchased used in 2011 year. A similar tester is Capanalyzer Model EDS-88AII

ECG Semiconductor Master Replacement Guide (Parts Cross Reference Book)

I received this book for free from a local electronics store that I used to buy parts from regularly in the 1990s. That store is now closed and the remaining branch is too far away to drive to but I occasionally mail order from them still. This book is old and the tattered pages and cover are taped back together. I use this book often. When I suspect a part is bad - I look up the part number in this book and it tells the specifications of the cross reference part in great detail. At the front of the book - a list of available replacement semiconductors is handy. It also contains drawings of pinouts.

ECG parts and NTE parts share the same part numbers and specifications - so when I find that I need a replacement - I will look online or call local electronics stores with a part number. I tell them it can be ECG123 or NTE123 for example. I sometimes can find a replacement part still in its package unused on big-auction-site. It is amazing that one little part can cost 2-10+ bucks each and even so the repair of that device for $10 is money well spent and very cost effective. I sometimes look for a reverse cross reference so I can broaden my options when buying a replacement part. There are millions of numbers that truly are the equivalent part. This book narrows down those millions of numbers down into several hundred part numbers.

The main pupose for this book - for me - is to compare questionable parts and decide if the part is still good. This book has saved me from buying a large quantity of replacement parts over the years. I can key-in on only buying parts that I know are truly in need of replacement.

My cat starting digging at this book 5 years ago and luckily I caught it just in time - before she tore it to bits. The cover and a few pages-in are now taped back together as best as I could. The holes are due to my cat. The worn out pages are due to my extensive use of this guide.







BK Precision model 815 Parts Tester
I purchased this tester approx 1997 brand new and been using it for over 15 years. This tester is a full service device and fully tests out-of-circuit/desoldered transistors, Diodes, SCR, LED, Resistors, Capacitors (Capacitance value only - no ESR), batteries, etc. This device helped me repair quite alot of electronics. The only test that it doesnt do is ESR which I believe this machine was made before ESR testing method was invented. I use this tester in conjunction with a 1996 edition manual to look up the cross reference value of nearly any semiconductor. Then I compare those specifications to what this BK Precision 815 Parts tester reads from the questionable part. I have purchased a few NTE and ECG replacement parts based soley on the readings of this tester. It has never let me down and is always correct. I have read alot of questionable parts on this tester and resoldered them back in circuit knowing that this tester proved the part in question was not bad after all. It has saved me from buying replacement parts un-necessarily. I can key-in on ONLY buying a replacement part which are for sure needed.

The above pictured tester shows a rubber protective cover. Mine was one of the first ones made and didnt come with that rubber cover. It still sells for the same price that it did 15 years ago. For the last few SCRs that I tested - I couldnt get my meter to over-range (the first 2 tests pass and the last test fails to over-range). So I ended up buying an SCR twice un-necessarily. I'm starting to think there may be a component inside that has gone bad. Fixing a tester is one of the hardest things to do. You need a tester to test a tester ... and if you rely on that tester and you only have one - then ... I'm not truly convinced yet that it doesnt work for SCR anymore. I will refrain from repairing that which works. It may be that those 2 SCRs fooled it or it may be that the tester has a bad part - I'm still undecided. If the reader has a suggestion on which internal component to check - let me know. The Duoyi DY294 shares many of the same functions - so I am able to test my tester with a tester ... LOL


I remember seeing a bright yellow Clone of this tester on big-auction-site. Unfortuantely I no longer have that photo.

DY294 English manual download above (my tester came with a foreign language paper instructions)


This tester has some unique features which allow me to test parts I could not otherwise test. It also internally scales up the voltage for certain tests- for example it can generate over a thousand volts for certain tests yet only 4ea AA batteries power this tester. It tests alot of parts' parameters so it can be compared to book specifications. For example when deciding whether the part is good/bad - comparison of data found in ECG or NTE semicoductor replacement data books - comparing what you see on this tester can be compared with those listed in the ECG or NTE books for their subtitute cross reference part values.

Some tests for varistors or transistors with internal diodes can be checked with this tester. It is a very handy device for alot of things found in most everyday devices- which previously there was no easy way to test them that I know of. Care must be taken to set the dial correctly and not flip the dial after the part is installed otherwise you can expose a part to the wrong test and apply too much power to the part accidently. Keeping a notebook on how to test a part is important so you can repeat that test the same way next time too. The apearance of this tester is deceivingly simple. It is labeled as a transistor tester but it is so much more than that. It not only tests standard transistors but all of the oddball ones too and many more parts.  It is very versatile and performs odd-ball tests that my other testers dont do. There are a few tests that a few of my testers have in common.

On some tests the TEST button is pressed and on other tests the TEST button is not pressed. Read the specifics on whether that test requires the TEST button to be pressed. Note that when the TEST button is pressed - the red LED "HV" next to the TEST button - lights up.

Purchased brand New in 2012 year.


Duoyi DY294 Tester Notes


Test 4ea AA internal batteries condition

(no components connected) turn dial to the right "2a(Ic)" The display shows battery volt (4ea AA batteries at 1.5v each should give you 6volts or better - the tester will work with weak batteries on most functions but some functions require peak batteries to give accurate reading) It is not necessary to press any button with this test.


AC Adapter

6V DC 20A using the jack on lower righthand front panel. + is the center connector. When using the ac adapter - make sure internal batteries are removed.


Voltage Regulator Testing

78XX and 79XX etc insert in 321 holes. With 78XX the regulator faces towards me. With 79XX the regulator faces away from me. Move dial to "78xx" or "79xx" and press TEST button and read display volts. Internal 4ea AA batteries need to be strong for accurate results. For example 7806 installed correctly with good batteries installed will show 06.0V when Test buton is pressed. Make sure your parts legs are free of excess solder or it will "booger up" your test holes as it is a tight fit since the legs just barely fit through the holes.


LED Test

Turn dial to "10mA(Ib) NPN (Put long lead of LED in "C" hole. Put short leg of LED in E hole) The led will shine brighter in other dial positions but this lower power position is safest for the LED as you dont want to burn out the LED - just test it. 10mA is enough to light most average LEDs without harm. Over time/decades of use - some LEDs grow dimmer with age. I suggest that dial is turned without anything inserted. LED should be installed AFTER dial is turned so as to avoid higher power ranges which can damage lower power LEDs. Display shows turn-on voltage of LED. Putting LED backwards does nothing and LCD shows only internal battery voltage of 4ea AAs installed. Typical red LED will show 1.76V for example when inserted correctly. No buttons are pressed during this test.


Zener Diode Test

Use E and C holes. Set dial first before inserting part. Set dial to "200V" NPN. Insert zener diode into E and C. Stripe side = C hole which gives Breakdown voltage when you press TEST button. Insert zener diode with stripe side = E which gives Forward Voltage Drop voltage when you press TEST button. Remove part and move dial to ICEO NPN and then insert diode (both ways) press TEST gives ICEO reverse leakage current. Having good fresh AA bateries installed is important for accurate reading


Varistor "Operating Voltage" Test

If the Varistor's value is 300V or below then use 200V NPN setting.

If the Varistor's value is above 300V then use 1000V NPN setting.

(300V is not a misprint and 200V is not a misprint and 1500V is not a misprint)

Turn dial to "200V NPN" or "1000V NPN" depending on your varistors value (see above note) Locate the capacitance test socket located in the lower right hand corner of the tester. Warning - This is a high voltage test - keep your hands away and dont touch any part of the meter or varistor during test. After dial is set and you have inserted varistor into the capacitor test socket - then press TEST button. The display will show the "operating voltage" on the display. It may vary a little from that written on the part. Release TEST button. Set dial to off before removing varistor. Avoid electric shock by not touching any part of the tester or varistor. This test generates up to 1500volts. Be very careful. I know of no other tester which can test a varistors "Operating Voltage".

Varistors and Disc Shaped capacitors look similar - be sure you identify the part correctly. Only run this test for Varistors.


Polarized Electrolytic Capacitor "Withstand Voltage" Test (medium size or smaller barrel shaped caps)

Locate capacitor holes labeled C+ and C-. Move dial to 200V NPN. Insert the legs of the capacitor into the correct socket hole. The stripe side of the capacitor is the minus side. Read the capacitors voltage and write it down. The way the capacitor is inserted - makes the capacitors value as writton the capacitor itself - faces the wrong way - so writing it down helps you remember - not to exceed the voltage that was written on the cap itself. This is a slow test and takes awhile and is a battery hog - will drain your batteries. Press TEST button and keep it held down until your voltage increases to the voltage written on the cap itself. This meter only tests the "withstand voltage" of the cap. It does not test ESR. It does not test capacitance. I know of no other tester which can test a capacitors "withstand voltage". It will even test capacitors which have a couple of hundred volts "withstand voltage" value.

Remember to discharge the capacitor by shorting the capacitors leads together before and after this test to prevent personal injury from a charged capacitor. Dont touch a charged capacitor's leads or partially charged capacitor. A DC 6V 2A power adapter is recommended for this test (plug into DC6V receptacle located just above the capacitor test socket holes. Otherwise fresh batteries are needed for accurate test (remove batteries when using power adapter plug). Test will quickly drain batteries. A bad cap will not charge or the voltage will cease to climb or will stall or will hesistate. A good capacitor will climb steadily but slowly towards the voltage. Once you reach the voltage - then let go of the TEST button. Do not surpass the voltage written on the capacitor. For example - if the capacitor being tested is a 16V6800uF then do not exceed 16v - after it climbs to 16v on the display - be sure to release the TEST button. I dont know what the consequence of not releasing is - possible capacitor rupture or worse or tester damage or capacitor internal damage - unknown. I suggest only testing it properly.


Transistor PNP and NPN (standard types)

ICEO Reverse Leakage Current test

Turn dial to ICEO (either PNP or NPN depending on which type the transistor data sheet indicates). Use a datasheet or by cross-reference to a substitute candidate data - which legs are EBC or BCE.  Insert into the correct socket holes in the tester as appropriate BCE or EBC. Press TEST button. The display should read "000" to indicate that the transistor is not leaky. Anything other than "000" denotes leakage and the transistor is faulty. Remove transistor. Turn dial to off.


hFE (gain) test (3 tests gives gain at 3 fractional amps settings) - make sure your transistor can handle this amperes

Turn dial to hFE 10mA (PNP side or NPN side depending on datasheet specification) Use a datasheet or by cross-reference to a substitute candidate data - which legs are EBC or BCE.  Insert into the correct socket holes in the tester as appropriate BCE or EBC. There is no need to press TEST button. hFE (gain) is shown on display. Compare to datasheet.


Turn dial to hFE 1mA (PNP side or NPN side depending on datasheet specification) Use a datasheet or by cross-reference to a substitute candidate data - which legs are EBC or BCE.  Insert into the correct socket holes in the tester as appropriate BCE or EBC. There is no need to press TEST button. hFE (gain) is shown on display. Compare to Datasheet.


Turn dial to hFE 10uA (PNP side or NPN side depending on datasheet specification) Use a datasheet or by cross-reference to a substitute candidate data - which legs are EBC or BCE.  Insert into the correct socket holes in the tester as appropriate BCE or EBC. There is no need to press TEST button. hFE (gain) is shown on display. Compare to datasheet.

Example C2166 shows "023" which is a HFE gain of 23 at 10uA in socket BCE.


VCE(sat) Collector to Emitter Saturation Voltage (2 tests at 800ma and 2A - not all transistors can handle this amperes)

Turn dial to 800mA(Ic) (PNP side or NPN side depending on datasheet specification) Use a datasheet or by cross-reference to a substitute candidate data - which legs are EBC or BCE.  Insert into the correct socket holes in the tester as appropriate BCE or EBC. There is no need to press TEST button. VCE(sat) is shown on display. Compare to Datasheet. (be sure your data sheet shows it can handle this 800mA before testing) Batteries must be fresh for accurate results (otherwise remove batteries and use Ac adapter 6VDC 3A)


Turn dial to 2A(Ic) (PNP side or NPN side depending on datasheet specification) Use a datasheet or by cross-reference to a substitute candidate data - which legs are EBC or BCE.  Insert into the correct socket holes in the tester as appropriate BCE or EBC. There is no need to press TEST button. VCE(sat) is shown on display. Compare to Datasheet. (be sure your data sheet shows it can handle this 2A before testing) Batteries must be fresh for accurate results (otherwise remove batteries and use Ac adapter 6VDC 3A)

Diode (standard types) Reverse Breakdown Voltage

Turn dial to ICEO(2000uA) Insert diode into E and C (either PNP or NPN side of dial will work but - or + on display may be opposite) For example on 1N4003 diode turn dial to npn side ICEO(2000uA) stripe of diode goes into C hole. Non-stripe goes into E hole of test socket. Press TEST button. Display shows "000" leakage. Remove diode and reinsert opposite (stripe goes into E hole and non-stripe side goes into C holeof socket) Press TEST button shows "1252" Reverse Breakdown Voltage (weak batteries 5v) Remove diode and turn dial to off.


Dual Fast Recovery Power Rectifier

Turn dial to ICEO(2000uA) NPN side of dial. Insert middle leg into E of large socket. Touch side let to C raised metal contact. Press TEST button. Read display. Release Test button. Rotate Rectifier keeping the middle leg in E hole. Rotal so the other outside leg touches C raised metal contact. Press TEST button. Read display. Remove Dual Fast Recovery Power Rectifier. Turn dial to off.

(Note turning the rectifier such that the middle pin touches C raised metal contact and the outside pin (1 test for each outside pin)  goes into E hole. Press TEST button gives "000" display. Remove Rectifier. Turn dial off.

Example MOSPEC F12C20C gives "000" leakage result and "1257" and "1257" reverse breakdown voltage result (weak batteries 5v)


Transistor Parameter Testing Note

Basic Functional Testing transistors can be accomplished by Gain (HFE_ and Leakage for most  transistors and it will catch most issues. This next section is about advanced transistor testing "parameter" testing.

The parameters of a given transistor can be determined by inserting the BCE legs of the transistor into non-matching BCE combinations of the socket (BEC, CEB, EBC, ECB,  etc many combinations). This produces a wide variety of test results according the the mismatching of leg to socket hole mis-combinations. This "mismatching is not arbitrary and it is not done willly-nilly or random. Follow the below instructions step by step in order to see the transistor "parameters" (I will document this later - to be continued)


To Be continued at a later date


odd transistor types
FET
SCR
Triac
high voltage non-polarized disc capacitors
AC filter capacitors


Too many to list (this is a work in progress)







HP 990B SMD tester

is a Resistance / Small Voltage / Standard Diode & Zener Diode /small battery / Capacitance (not ESR) tester which has built-in tweezer probes (and included add-on handheld probes). I use this occasionally when I work on surface mount boards with very tiny soldered-in components. The best feature about this tester is its ability to identify Zener diodes voltage rating value (not as accurate as my other tester but good enough to determine if a component is blown). Another unique feature is with the push of a button the tweezer tip polarity changes opposite which makes testing standard diodes simpler as the buttonpress allows testing a diode in both directions easily. 

For example when testing a brand new in the package 4.7v Zener diode this tester will give a value of 4.01V and .063 reverse. Good enough for testing purposes - to determine if a zener is good/blown.

It has the functionality of a VOM multimeter with some additional features ( for example like zener test ) - however it is only for small voltage sensitive rating parts - not for use on big voltages or powerful components. Runs on 2 AAA batteries Purchased Band New in 2012 year approx.






Fluke 73 Multimeter

This is a very old tester and works very well. I trust it to give me the correct display of Voltage AC or DC or Ohms or Amps or Diode Test or Continuity Beep. It is easy to use due to its autoranging and autopolarity. It runs off one 9volt battery which lasts for more than a year of my use. I own several multimeters or VOM meters but this one gets used the most and I keep it handy to test batteries and electronic components etc.

My Fluke 73 is dead-on accurate.
For example I noticed a year ago that my AC power was higher than it was supposed to be. I initially caught that over-voltage when I tested the outlet with a Killawatt meter (also very good) and then I doublechecked the voltage on my Fluke 73 - same reading. When I called the electric power company to report 126.5V AC from my outlets the lineman that arrived confirmed this fact and said that he also measured 126.5v AC and he said that it is high but still within electric company guidelines - no repair done to the line. (Illinois USA AC varies nowadays from 123 V AC to 126.5 V AC and it is a bad idea to plug in older appliances and electronic gear without stepping down the voltage to within range of what the device requires.)

The Fluke 73 is a professional tester and is trusted by many millions of technicians.

Production Devices   Model 85 Transistor Tester - Tests small signal transistors both in and out of circuit - runs on one 9v square standard battery and gives a tone when a good transistor contacts its 3 prongs on the solderside of a circuitboard. NPN/PNP switch is manually set and correct EBC CBE ... orientation is manually set by turning the tester to contect the correct transistor solder trace. Made in approx mid 1970s and came with the rubber-boot style extension cable as shown. The above picture is a postcard. I purchased this tester in July 2014 and required quite a bit of cleanup as it was rusty and in disrepair. I am trying to obtain a replacement switch for it as mine is cracked due to someone pressing on the PNP/NPN switch as if it were a pushbutton switch and cracking it. It is a 3PDT (3 pole double throw with 9-pins ) switch with (center to center space 1-1/8") threaded screw holes which I have located one switch at a electronic parts distributor close replacement but the holes are not threaded so I am continuing to look to see if I can find one that is a better match. I am able to test it so I know the circuit works. It is functionally the same as the model 100 shown below which I also own.

It doesnt test all transistors but tests enough that it is a help when checking for transistors that are bad - without desoldering the transistor. It has a brushed metal round case that resembles a microphone. The back cap is a press-fit and inside is the tiny headphone-like speaker and the speaker is moved outside the case dangling to replace the battery. The plastic cap on mine is original but doesnt hold itself in place- the previou owner used a piece of electric tape for a press fit which was unbelieveably very very very tight. I used a piece of celophane tape as a spacer for now. A set screw would be a better way to do this.

It runs on 1ea 9V standard rectangle battery and I always take out the battery because there is no power switch.

Production Devices    Model 100 Transistor Tester - Tests small signal transistors both in and out of circuit- runs on one 9v square standard battery and gives a tone when a good transistor contacts its 3 prongs on the solderside of a circuitboard. NPN/PNP switch is manually set and correct EBC CBE ... orientation is manually set by turning the tester to contect the correct transistor solder trace. Made in approx late 1970s or early 1980s and came with the prong style extension cables as shown - these extension cables plug into the back end of the tester - near the speaker. The 3-pin prong on this model is slightly flexible, and this 3-pin prong is at the pen-tip end of the tester. I purchased this used in July 2014 as pictured (the seller forgot to send the green card which I'm still trying to obtain)  The ad was on big-auction-site and the seller had 3ea testers and 2 boxes and 1 set of cables and one green card. I was specific in my offer - mentioning all the parts I wanted and my offer. I think 2 of these are enough for my needs - having both a model 85 and a model 100 and both being functionally the same - 2 of them are good enough - I didnt need the other ones (see pic showing all 3ea testers the seller had for sale). I still hope to get my green instruction sheet - the seller said he will send it 7/14.

It doesnt test all transistors but tests enough that it is a help when checking for transistors that are bad - without desoldering the transistor. Battery is accessed by unscrewing 2 screws and separating the case halves.


It runs on 1ea 9V standard rectangle battery and I always take out the battery because there is no power switch.

AVO TT169 Transistor Tester - in-circuit or out-of-circuit

This tester works very well to locate dead or shorted transistors in circuit. It is a 2-handed IC tester. One hand is holding the body of the tester and pointing the sharp green probe and touching it to the BASE of the transistor (usually the middle leg but not always) and the other hand is holding the red/white probe and touching it on the EMITTER and COLLECTOR of the transistor. One feature I really like is that the internals of this tester are alternating back and forth between Base and collector - so it is not important to know which one is which while testing. The result is a blinking LED if the lowpower transistor is good. The blinking LED is due to the internals switching back and forth between collector and emitter on the red/white probe. This feature is a big time saver. I'm going to call this feature self-permutating as it hunts on its own for Emitter and Collector on the red/white probe.

Quickly scanning transistors is easy and can be tested in just a few seconds each. If the transistor doesnt flash then adjusting the dial to try and find a setting where a flashing LED is observed or switching the NPN/PNP switch is needed. If the LED flashes then the transistor passes the GO/NO GO test.

The manual shows how to test diodes and power transistors.

Some Words of Caution
The power jack is not for connecting power (runs only on internal 3ea AA batteries). The power leads which are colored with a black wire and red wire are not power leads at all. Never connect any power to the power leads. The red and black wires (and alligator connector) and power jack is for testing power tansistors. The red and black wires are not needed for testing small signal transistors. There us another typo in th emanual - the lightbulb does not light up during self test - only the LED. The lightbulb lights flashes when testing power transistors and pass. Probe leads are very sharp and hazardous - CAUTION

It runs on 3ea AA batteries and I always take out the batteries because there is no power switch. Also The probe tips are very very sharp and hazardous. This tester was made in the 1960s and I was lucky to find in pristine condition in 2014.

I use the above pictured IGBT & Mosfet tester when I test the high power IGBTs. It has three leads and alligator clips. The LED lights or doesnt light to show correct or incorrect operation of the IGBT when the red button is pushed. It is a nice easy way to functionally test these parts. Some IGBTs fail catastrophically (melted/burned etc) on devices --to-be repaired- but others fail and there is no outward sign that the part is internally bad. The click sound and the red light means it is a good part. I have run into bad parts - and the tester either stays lit or stays off or doesnt respond to the button press- which means the IGBT under test is bad. It can also functionally test Mosfets. Runs on 1ea 9V battery. Purchased Brand New in 2011 year.





I own several versions of Willem Eprom / ROM/ Prom/ EEprom / Flash / PIC Programmers ranging from early DIY etched board to the above online-purchased advanced model. Pictured above is a PCB50 which is a digitally selected (no dip switches) pushbutton selected model. I can select the voltage and other paraameters with pushbuttons. The LED bargraph lights up according to my settings. It is exactly like the earlier models of DIY Willem and has the same functionality of my other boards - but I like the digital selection and use it/prefer it 100% over my other Willem programmers. This is a parallel port version which uses the parallel cable to communicate with a PC. I use a dedicated older PC for this Willem programmer. It is powered by the USB cable but the USB only supplies power to it. I have used this WIlem to flash/reflash BIOS and update ROMS and burn chips for use in projects. The Willem programmers are very useful - their only drawback is lack of thorough documentation. So I had to figure out each and every chip setting manually - for all chips I have ever burned. You would think that an online source for these settings would exist - but really and truly there is no source for this list.

I have an interest in compiling this list of settings as I have figured out quite a chip few settings on my own and I keep a detailed notebook on what settings worked for me for each chip model I have burned. I use Willem Pro software version 0.99kb for PCB5.5c running an older pc dedicated for chip burning which runs WinME and has both a USB and parallel port and 1GHZ processor which is sufficiently fast enough for high quality burns.

I have successfully figured out the settings for the following chips using Willem, and I have made notes for the following:

PIC12F629

SST 49LF040B

SST 49LF004B

SST 49LF002A

Winbond W39080APZ

Winbond W39V040BPZ

A29002IT-70

SST MPF 39SF020A

Winbond W49V002AP

Winbond W39V040FCPZ

MX29F004TQC-90

ASD AF49FZ008-12 0018

2764 older UV erased chip

If you need the above settings - contact me to purchase these Willem settings for a few dollars each payable by paypal for the DIYer. Also available is custom re-flashing the file onto a chip that you provide. I can read existing chips, erase chips, and reflash old chips and burn new chips. Some people like to send me their chip. Some people like to do it themselves- but do not know how. I charge a small fee. If have a chip that you want settings for or custom programming - let me know, and I will quote a fee. Sorry I cant program MAME roms for you due to copyright.




Global Specialties LM-4 Logic Monitor for CMOS or TTL ICs

This device is basically a "Logic Probe" It comes standard with a 40-pin ribbon cable and attaches to the top of the tester with an IDC connector. The IC Clip end is a 40-pin Wide Dual In Line ( DIL ) which can attach to many chips 40-pin or shorter. For much smaller chips and or narrower chips a self-made adapter is necessary. Imagine 40ea logic probes attached to an IC alligator clip - that is what this device is. One LED connects to each and every pin on the IC. The LED is either on/off/blinks to show the logic state of that particular pin on the IC. Of course the main purpose of this is to monitor a live circuit while it is under power and operating.

Sometimes a chip will have a bad pin and the rest of the IC operates. This bad pin will stand out as being in a different state when compared to previously tested boards of the same type (in reference to my notebook notes from previously tested boards) So it is important to keep a record of boards I test regularly and compare them with drawings or sketches or descriptions that I have observed.

For example a board previously tested may say in my notebook, "IC XXXXX ... pin 6 ON" but when I test another board - I may actually observe that pin 6 is actually LED off. Then that makes me suspect that this chip has an issue (When one chip has an issue - this also affects other related ICs LED status too). Many boards have a boot-up logic state - as soon as that board is powered on - certain LEDs light. If something is not right about the light up or off sequence - it is observable with this tester. I tend to use this tester by clipping over the IC and then powering up the board under test - that way there is a predictable initial viewing of logic state of that IC in my notebook. Sometimes I will elaborate in my notes about what the chip looks like after bootup is complete or in various modes.

I like a Logic monitor (rather than a logic probe) because it is safer for the circuits and ICs - due to cliping an IC Clip over the chip - rather than probing around with a 1-pin logic probe. The IC Clip is locked in place and can be attached with the power off. So there is absolutely no reason to ever short 2 adjacent pins on an IC (by probing with a Logic Probe for example).

I also like being able to see 14-pin, 16-pin, 20-pin, 24-pin, 28-pin, 40-pin ICs on this one tester using homemade adapters and clips. The simultaneous view of all pins logic state is beneficial. It doesnt draw any substantial power from the chip under test and allows that chip to function like it normally would.  I share the same set of homemade IC clips and ribbon cables and adapters with my other IC testers.

I sometimes video record a sample working board showing the LED state of each and every IC chip as a reference. This is especially true of ICs that there is no data sheet for and may be a custom IC or proprietary IC. Sometimes one board is a different version or has a different set of EPROMS/ROMS that make it boot up differently so a different combination of flashing light sequence doesnt necessarily mean the chip-under test is bad. This tool is used to give a clue as to which chip may or may not be bad as some chips fail catastrophically and some ICs just weaken with use over time or develop strange or intermittant glitches - for example LED stuck on.

If the LEDs flash/ON/OFF state according to my notes (from previously tested boards) - that chip is probabably not the issue with the board or a more in-depth testing is needed on a different tester.

The IDC connector lends itself to changing out to a homemade IC Clip of any style (DIL, DIP, SOIC, etc) and there are a tremendous amount of IC chip pins and styles including surface mount that I make custom attachments/ribbon cables for my own use as I need them.  Big-Auction-Site is a good source for used or new IC Clips.





 

Vacuum Tube Testablility For U-Test-M Tube Tester

I am making a list of testable tubes here. This list is not necessarily about cross referencing. This list is about what settings to use for the U-Test-M Tube tester - as there are more tubes in existence than are listed on its rolling chart. So this Testability tube list will allow me to take unlisted tubes and know which "known tube" it is tested the same as on the U-Test-M roll chart.


I hope I explained that clear enough - this is not a substitution chart for you to swap tubes in your TV set or Radio. This is a chart which expands the capabilities of the U-Test-M tester. I need to look up your tube on my list and then find an underlined tube heading - then use that "subtitute tube number" to look up the setting in the roll chart. It is an in-direct method of expanding by many times the capabilties of the U-Test-M.



The U-Test-M is regarded as the pickiest of all of the testers- people regular folks who repair their own TVs and Repairmen often say - "when I test that tube on my Hickock it passes just fine - but on the U-test-M - it fails it. That XXXX drugstore/tv repair shop just want to cash in on selling tubes. Dang-nabbit (or worse)" Well I look at it this way - The U-Test-M is for people who want to restore a tv or radio to top notch condition - rather than "good enough". Still it doesnt test Mutual Conductace - so really having more than one tube tester is a good idea. I plan on owning a HIckock and a U-Test-M - Both (I dont own any tube tester at this time). There isnt any reason why a shop should only have one tester. If the tube passes all the tests from every tester - then that tube is very good. If the tube is very good - it should be able to pass even the U-Test-M. I'm still looking for a U-Test-M model 2500 I havent purchased one yet- they are usually sold by sellers several states away and I'm hoping to find one that is within driving distance. Let me know if you have one for sale.


With tube based electronics - the weakest point is not the tube - it is the paper and wax capacitors - that is the souce of most problems. The tube is easy enough to se if the filament is glowing or not. Just becaus the filament is glowing - doesnt mean the tube is good. With the invention of the ESR meter - testing those old caps/replacing a few bad ones is a breaze and usually enough to get an old set up and running. But the U-Test-M made testing tubes easy enough for the Do-It-Yourselfer and I remember a local Zayre store (you dont hear that store name too often anymore) had a U-Test-M model 2500 at the front of the department store just in front of the cash registors and to the right of the Service desk. I can remember testing tubes at the Zayre store (as a customer using the stores self-serve vacuum tube testing machine in the middle 1970s approx) The Zayre store was a department store like Kmart, Target, Walmart, Venture etc.


It will take quite a while to make this list and may contain errors so use this on an at-your-own-risk basis - as I will do my best. I am using a multi-column feature and this is something that is new for me when building my webpage - under construction - your patience is appreciated. This section Commenced 1/25/14

XRAY of Identically marked chips showing the internals (above pictured) Sometimes alike marked parts can be significantly different in design and may have a incompatibilities. Testing is best - even with like-marked parts or parts which are visually identical.



VZ IC Tester pictured above (list of chips shown at bottom of page on left side in blue) My IC Tester # 3

It has search function and chip number can be manually typed using the keyboard. This tester was sold under 2 different brand names.

Manufactured and purchased new in 2012 year.



GUT IC Tester pictured above (list of chips shown at bottom of page on left side in white) My IC Tester # 1

It has search function and chip tested can be manually selected from internal Menu lists. This tester was sold under various names by several vendors. 

I bought this used and had a heat damaged LCD display. I ordered a new LCD module which is a standard type. This tester performs very well and has no cosmetic or functional issues. If I didnt tell you - no-one would know it had been repaired. The only difference is the LCD contrast is higher on the new lcd module than on the original and display has a slightly greenish color.

Manufactured approx 2005 year estimated. Purchased used in 2012.




Precision-Motion Chiptester Model CT2 pictured above (list of chips shown at bottom of page on right side in red) My IC Tester #4

Notes: This is the full version machine with optional internal ROM upgrade factory pre-installed (" CT1 with 4164 & 41256 TEST "). Originally sold by Digi-Key Part Number CT2-ND in approx 1988 year. There is no keypad to enter the chip number. Simply insert the chip into the socket. The manual tells you the correct display for a good chip. Usually the display shows the last few numbers of a chip - as the correct response for a passed test. On other chips the display may show a letter and number combination or simply a number or a subtraction symbol next to a number etc - the manual deciphers the display and what it means. Reading the patent also helped me understand what this tester does. It is very sophisticated yet simple for most chips. There are some chips in the list which require 20 adapters to be self-made as some pins on the self-made adapter need to be cut-off or jumpered. I do not have any of these self-made adapters. Between all of my testers - the chips which the Chiptester requires a special adapter to be self-made - are available as part of a built-in test on another one of my machines. It is important to look up the chip number in the manual before plugging it into this tester. Estimated manufactured 1988 approx year.

This IC tester was purchased used in 2012.




YBD IC Chip Tester pictured above (list of chips shown at bottom of page on right side in yellow) My IC Tester # 2

Purchased and manufactured New in late 2012 year online from a Hong Kong Seller. Purchased the optional add-on 3-socket adapter 2013 year direct from the mfg. No automatic search function on this tester. It has loop function. The number of ICs this unit can test is very very extensive. For some ICs - the chip must be put with pin one at top of ZIF socket - other tests require the chip to be put in with pin 1 of chip to pin 2 of the tester socket (the display prompts the user how to insert after the chip number is entered.) The manual's diagram showing how to use the adapter differs from the markings on the 3-socket adapter - so I have not plugged this $40 3-socket adapter in at all. The mfg is checking on this to see if they can provide me with an updated instruction sheet to clarify the proper use of this adapter board.

MCT IC Tester pictured above (list of chips shown at bottom of page on left side in green) My IC Tester # 5

Made in 1989 year approx. Memory chips DRAM are installed in the test socket reversed/backwards and furthest away from LCD. Has auto search function and also arrow keys to select chip from internal list. I have the version with the yellow button (some other units have a red button) Purchased used in 2013 from USA seller. This is a very speedy tester and with a press of a button recognizes a chip and tests it very speedily. You can also manuall\y select the chip number from a chiplist and scroll through that list. It runs on a 9v standard battery. Memory chips are tested upside down (notch facing user) and TTL chips tested up-side-up (with notch facing away from user)

The Blue Tester is often advertised with the set of features of the yellow tester. There is an added feature of O+ENTER for power off. The instructions included with the blue tester for many original buyers of the blue TSH-06F tester as many came with the instructions for the TSH-02F. The following photo is in a different language but clearly shows that a combo of buttons O+ENTER and other combinations perform functions (unable to read this language so it is unclear which key combinations perform fucntions. As of this writing the yellow tester is becoming rare to find 6/14 and I only see the blue tester TSH-06F being sold on big-auction-site. Functionally these 2ea models of testers are alike except for Off key and P key combinations. The blue tester also displays "self test Pass" (as shown in one advertisement) whereas the yellow tester internally self tests but doesnt display the message. If the yellowe tester fails the self test function it will display ERR 1 or ERR 2. This is a very speedy tester. It runs on one 9v standard battery for the TSH-02F (Yellow) and 2ea AA batteries for the TSH-06F (Blue) there is a built in voltage check meter which you can monitor the battery voltage remaining in your battery. It is interesting to see how much the battery drains after x-number of chips tested. I have not counted how many chips I could test on one battery set. Some tests of certain ICs and certain components drain the battery more than others. I sometimes use a standard battery and sometimes a rechargeable 9v battery for IC testing.

As of this writing I am unaware of the purpose of the P key. The answer is probably contained in the jpg file but since I am unable to read that languae - I dont know what the P key is for. I assume it is for self-test but I dont know for sure that is only a huinch on my part. If you have a blue tester and figure out what the P key is for - let me know.

TSH IC Tester pictured above (list of chips shown at bottom of page on left side in orange) My IC Tester # 6

Purchased new in early 2013 year from Singapore. Tests Digital ICs, a few Linear/analog ICs, Zener diodes and a few more. I imported this tester direct from the mfg and is one of the first few produced. This device did not come with a list of chips - but the instructions specified the families of chips that it can test. I enter the family in the menu and then choose the chip number within that family and in most cases this tester handles it well. Not all chips in every IC family series are supported - as I find out sometimes when it displays "not supported" meaning that this chip is not on the internal list. This tester is great at differentiating between LS (lowspeed type) and HC (highspeed type) chip types.


There was no chiplist included with this model of IC tester - I have created a chiplist for it - see the bottom of pages. I have manually gone through each and every chip in the internal menu one-by-one which was a laborious task. I made notes on which chips it recognized and which ones were not supported. Why the mfg didnt include a chiplist - I dont know - but I have one now because I made it myself - the hard way. This chiplist is identical in both the TSH-02F (Yellow) and TSH-06F (Blue) testers. I used up 1-1/2ea 9v batteries making this chiplist - with no chips in the socket - just going through the menu and looking to see if LCD display has a reaction to manually entered chips to create my own chiplist.




 

Micro Scences MSI Digital IC Micro Circuit Tester Model ICT-101 (pictured above)

IC Tester #7.


(List of chips left side purple color - see below)

There is an empty socket on the front of the machine - which  is for 24-pin IC chip clip (was optional accessory - but mine doesnt have this clip. As I read from the book this optional clip is only for 74154 IC which is a narrow .300" IC same as most 7400 chips so a special .300" IC clip 24-pin is needed and these clips are uaully designated "24/3" to denote 24pin clip for a standard .300" narrow IC). I have 2ea total IC testers that can test 7400 TTL and 4000 CMOS chips in-circuit while the circuit is powered on (the MSI ICT-101 and the B&K 560). It is a large tester 5"x12.5"x11.63" and weighs 7.63lbs. This tester is estimated to be mfg in 1983 and is complete with manual and ground cable (Pomona Electronics 3780-36-0) and 20-pin ribbon cable with end clip. Most of the internal chips are 7400 series with 1 static RAM and several ROMs. There is a D800 microprocessor in there also. A board which looks like a memory module is covered in factory black epoxy resin to shield the part numbers and protect from anti-static. The 2ea upgrade ROM which adds a few more ic chips to the list - is not in my machine (I have the standard ROMs with 2ea additional empty sockets for the upgraded ROMs to go there. My sockets U10 and U13 are in need of the upgrade ROMs. If you can provide these missing U10 and U13 ROMs - let me know. I realize it will be difficult to find these ROMs 35+ years later.

This IC Tester has internal diagnostic checks and functionally tests itself in many ways when powered on. The menu lets you choose settings for ROM RAM CMOS TTL and more. My tester does not have the optional RAM/ROM test feature. My tester is a basic model and only for in-circuit testing of 7400 and 4000 series chips (this tester does not test every chip in these series/families of chips). The add-ons were not purchased by the prevous owner and this is a factory stock machine - now fully functional - after I replaced about $25 worth of discreet (common solder in place type) components and 2ea ICs purchased online. When I purchased it - it had a scrambled/garbled display (looked like this @#$%&*@# with all random characters) and was unresponsive to key presses. It had a bad transistor in the display board and a bad SCR and 2 bad 7400 series chips. The 1ea desoldered/now socketed static ram chip 6116 tested fine on my tabletop IC tester. Luckily the proprietary memory board was fine as the factory covered it with black epoxy and would have been difficult to remove epoxy. Since all of the chips were soldered in place - I had to make my own IC desoldering tool by hand and I removed each chip and socketed it. I checked each componenet one-by-one with a parts tester BK Precision BK815 & various handheld & tabletop IC testers shown on this page. The zener diodes I tested with Duoyi DY294 tester & TSH-021 IC tester which gave correct voltage checks (see above photo which shows germanium diode inserted into IC tester for voltage check)  Several parts were replaced with NTE brand replacement parts purchased from Radio Shack online and a couple of parts were purchased online internationally. I desoldered chips carefully and used the same chip to go back into the IC socket. I did not destroy any chip when I desoldered with my homemade desoldering tool and was able to test them on my IC tester and knew they were fine. The online auction I purchased this ICT-101 IC tester from says it was "military surplus". the preevious owner attempted to fix it and boogered up alot of things. It took alot of un-boogering to correct. I solder very well and my solder joints look pefect.

The general concept for using this tester is - you have to have a live powered-on board to be tested. But the board under test cannot be underway. What I mean by that - is the electronics have to be idle and not operating. Powered on but not operating. The microprocessor should be removed or the crystal disabled so there are no oscillations. The ground is connected from the powered on board to the ICT-101 tester. Very important - the ICT-101 needs to be powered on first before any connections are made. It tests CMOS and TTL Digital Logic ICs in circuit on live boards which are not underway. I hope I explained sufficiently - what I mean by "powered on but not underway" as I'm trying to phrase things in everyday terms. The book calls it "the board has to be in a static condition" and "devoid of active ICs" and "effectively removing disabling or tieing clock generators."

The tester should never be exposed to 6v or more (6v would kill the ICT-101 tester). Check voltage (This is a 5v tester only) before testing and removal of oscillations prior to use. The tester should not be clipped onto a chip more than 1 minute or it may weaken or ruin that chip. A sense of urgency in quickly testing a chip is necessary. You cant stop and answer a phone or shuffle papers while using this tester - otherwise you will burn out the chip under test - or damage the tester itself. Any possible future repair should be easy now that all the ICs are socketed. Test equiment should always have socketed ICs - that is my opinion - as it makes for easier repairs and fault-finding/troubleshooting. It is interesting that the mfg of this ICT-101 tester had a lifetime warranty on this tester and is no longer in business. The book states that an ICT-101 is necessary to troubleshoot an ICT-101. So it takes a tester to fix a tester. If I had another in-circuit tester - I could have removed the microprocessor, clipped on the test clip, and checked each IC one-by-one. That would have caught all of tha bad parts except the SCR- which would still have needed to be manually desoldered for testing out-of-circuit. I have alotof IC testers as a "second opinion" about a parts condition is helpful and avoids false pass/fail and replacing good parts un-necessarily. This in-circuit tester is one more "second opinion" about an ICs condition.

This IC tester was purchased used from a USA seller in late 2013.

Update 8/5/14 I have completed the machine by addiing a second ribbon cable in the righthand socket. I found a professional 24-pin IC clip and ribbon cable made by Logic Connection which is NOS New Old Stock purchased from big-auction-site. This clip was hard to acquire as it got lost in shipping for 3 weeks and ended up in another country. The honest person who received it - sent it back to the seller, and then I received it after about 3 weeks. I also added a 24-pin ribbon cable connector. This now gives me the ability to test just one 24-pin IC chip on the chiplist which is a wide style chip.

 

This is a Portable Linear IC Tester LIC and is a handheld tester. It is my only linear IC tester at this time and my 8th IC tester. It has the same shape and style case as another one of my testers. I'm glad to have purchased this tester as I was looking for a used one for a long time. This unit came with the original AC power adapter which is 9VDC 500ma or can run on 2ea standard 9Volt batteries. Several companies sell this tester under various name brands. I have listed the chips it can test at the bottom of this page on the right-hand side in grey color. This tester was purchased from a Canada Seller on 11/13 and shipped to USA. Purchased (New Old Stock NOS and never used by previous owner) in 2013. Manufacture date estimated 2010 (this is a currently available item as I am writing in 2013). 

This Tester was purchased brand new NOS from a Canada Seller in 12/2013. This is my IC Tester #8





One thing I realized after I bought these test clips is that they have a "nail" head and - that part I knew by looking at the photos- But what I didnt realize is that one side of the row of nails is much shorter than the other side (not obvious when you look at the photo below). This is how they come from the MFG. So really after much searching for a clip on connector to make this detachable - i have come to the conclusion that I needed to solder onto these as a connector would work only on the long nail side but a connector would not reach the individual nails on the short side. Some of my connectors had the nail head chopped off (previous owner) which can be done with a Dremel rotary tool and cutoff wheel. I put heat shrink tubing on every soldered connection. I purchased a pkg of 10ea 26pin 2x13 IDC connectors as a lot and crimped this on the ribbon cable. Remember even though the test clip is 24-pin and the BK560 ZIF socket is 24-pin - the header is 26-pin- so it required a 2x13 IDC connector to plug into the header correctly (the bottom 2 pins are ground on the idc header).

Above pictured is a B&K Precision model 560 (sometimes referred to as a BK560) Digital IC Tester. It has a 24-pin ZIF socket for inserting chips for out-of-circuit testing. It has an IDC header for connecting an external clip of various pinouts. This is my second tester which can perform out-of-circuit testing. Soldered in chips can be tested without desoldering in most cases. There are times when the chip must be de-soldered from the board before testing. Since I purchased this machine used -it came with no ribbon cable clips so I made my own set of 5ea clips 14-pin, 16-pin, 20pin, 24-pin and a 20-pin microclip for SMD chips (I see quite a few 7400 series chips which are SMD nowadays so this miniature clip is necessary to test the SMD mini IC chips of the various chip families) This tester also has the ability to learn an unknown digital chip's truth table and store that data into memory chip storage for future comparison (see 4ea empty IC ZIF sockets one of which has a data storage chip installed). The list of chips is very long and I will add this chip list in the future at the bottom of this page in turqouise color and right-hand side as my time permits. This is my 9th IC Tester. I will add a photo of my self-made clips at a later date. For in-circuit testing using the external ribbn cable clip- the circuit must be powered-on but not in-progress. By not-in-progress I mean that the circuit must not be running or operating - but it must be receiving power. To further clarify - The crystal oscillating the circuit must be disabled so that the circuit is not underway or in-progress. The crystal oscilator must be removed. For eaxample when I test diskette drives - I connect the 5-1/4" disk drive to a PC power supply but the drive itself is not connected to the controller card. This in essence removes the crystal oscillations and satisfies the requirement that the circuit under test is not in-progress. The tester tests chips which are at a standstill and are not processing any data etc. This is my second in-circuit tester and the same not-in-progress requirement is found in my other tester for in-circuit testing.


This tester was purchased from a USA Seller on 12/13. This is my IC Tester #9




The above pictured Berkeley 998  is a Linear IC tester and is a vintage analog piece of equipment (estimated 1965 to 1975 estimated mfg year). I purchased the manual and tester from different sellers. I feel fortunate to own it as it is rare. I plan on testing op amps and voltage comparators. To be honest the manual only gives one example on how to use it and I need help on understanding how to use this tester. All of my other testers are simple to use and operate. This vintage linear IC tester is very capable machine but I need to learn and am going through the book but I can see that the book's one example is insufficient. I am also going through the internals to test components one-by-one as this is a used item purchased recently - to make sure it functions.  Ideally someone will share their notebook notes on step-by-step how to test alot of chips with this tester. The title of the manual I have is "Model 998 Linear IC Tester Instruction Manual" and has schematics / parts list at the end. At the present time I am unfamiliar with how to use this tester. I look forward to using this equipment as it will tell me the linear/analog values rather than just pass/fail. This will help me assess the condition of chips so I can make the decision to replace if readout is weak.


Somethings that are not clear - use of oscilloscope in conjunction with tester? Slider sellings. Use of knobs and switches and dials. I have the 16-pin socket and the book says there are various 14, 16 pin sockets available- I would like to acquire those additional sockets.


Any help or insights on how to use are appreciated. I would like to know step-by-step how to test LM310 and LM311. I hope a kind reader will educate me on how to use this well-made machine (through email or video?). My email address is drviragopete@att.net in case a kind soul will share their insights on how to test.


It is possible there exists a manual (I dont have that) that shows settings for various chips and semiconductors. I do not have any list or settings for various ics at all - only the very thorough (only 1 example in the book) example of testing Fairchild 709 which is quite hard to follow and understand. I purchased this tester in 12/2013 from a USA seller. The testing procedure is from a different era and I am having trouble grasping the concept. It is probably very easy but I am missing these necessary insights.


This IC Tester was purchased used from a USA Seller in 12/2013.  This is my IC Tester #10


Update 12/2013 I have ordered a NTE909D IC which is sealed in its original plastic bag - never used. I will use that 14-pin IC to go through the book's instructions for testing 8-pin 709 Op Amp. Due to the 14-pin rather than 8-pinout I will need to figure out which pin and slider switch needs to be used for this IC for proper testing. I noticed many other sellers of 709 chip or can package ic - the prices are skyhigh. I instead ordered this chip from RadioShack online for $3.60 w/free shipping and is a cross reference for the 709 Op Amp 14-pin edition and is a real bargain pricewise compared to sellers of other brands of 709 Op Amp. I will need to figure out the pin settings and make notes on the side of my book page - so I use the proper pinouts for the 14-pin chip.




ABI Digital IC Tester Chip Master Compact

This tester was purchased used and was mfg in United Kingdom on 2005 and has ROM version 2.00 which is the most current version for this model. It runs on 9V DC at 300ma by using an AC Adapter (I do not have this) or with standard 4ea AA alkaline batteries. This model of tester is rebranded under at least 1 other namebrand. Some models have a rs-232 port built-in which allows for user added chips and are considered the "Professional" series due to the ability for users to program their own test routines for unknown chips. My tester does not have this rs-232 port and I will use the built-in chiplist only. I see a downloadable firmware update on the ABI website for this model. I will check the firmware version and update it if needed. Hand-typed chiplist is shown in orange color on the right hand side "ChipMaster" I see some similar models advertized as being IC Tester / Identifier which refers to its ability to search for many but not all IC chips inserted in its ZIF socket. This is my IC Tester #11


I purchased this tester used 12/13 but the seller sent a non-working tester - the following files show how I got it to power up it and now works. Maybe it will help someone with a similar issue. I suggest only running this tester on batteries or its original power adapter. Do not use any ordinary AC power adapter - that is what the previous owner did and it blew out the tester. It now works well after repair. I may someday add a 5v internal voltage regulator - but for now it is un-modified except for the removal for the blown 5v or 6v bilateral/non-polarized TVS surface mount component (my best guess at what it was) which was causing a 390ohm short across the supplied power input. For now I am using it only on batteries - until I locate a replacement SMD part and possibly modify it later-on with a voltage regulator.

MBICT
Microcontroller Based IC Tester (Caseless and purchased New Sealed from big-auction-sites)

This is my IC Tester number 12

Microcontroller Based IC Tester which has no name-brand and has no case.
This was purchased 2014 from big-auction site and was difficult to obtain because I waited too long to buy it and at that time only one seller for this item remained. It was actually cancelled by 2 sellers which I tried to purchase from. One seller from another auction website told me the reason he cancelled was that he mailed it and then it came back with reason "Failed Xray Test" which means that security would not allow it to be mailed internationally. But I finally successfully ordered it from anotgher seller (same seller who cancelled originally) and arrived - great its finally here! Very hard to purchase but worth the wait.

There were no instructions that came with this tester. The original Ad that I purchased from showed the chiplist and I have included all the information inside this Zip File which I created.

ONE very important thing which was not on the website - not prionted on the circuit board - not anywhere.

The polarity of the power connector is center pin is positive +
The voltage required is 7-12volts DC.
(I use a 9v standard rectangle battery)

I made myself a power cord with a 9v battery clip and then connected it by soldering and heatshrink tubing to a DC power plug which I had in my inventory. I traced the electrolytic capcitors negative - side with a continuity tester (Fluke 73 multimeter set to continuity) and I knew that whichever part of the power jack had continuity with negative-side of the electrolytic capacitors was also minus on the DC power jack.

That polarity description is nowhere to be found anywhere online - I wonder how many people blew out their IC tester by hooking up the polarity wrong? I hope not. There is no voltage regulator on the circuit board. I recommend only running it on 9v battery power.

I tests well and has a very short chiplist - I'm glad to have it.

I purchased several cases and a keyboard and 9v battery compartments etc and I will decide/modify a case to work - will update this post as I figure out/modify a case for it.

I have added the chiplist on the bottom of page lefthand side "MBICT" and is only for a short list of 7400 chip testing.

Caseless IC Tester model TES200

Purchased this from Hong Kong and is brand new. I jumped on purchasing this new item as it has a long chiplist and price is low. I didnt want to miss an opportunity to buy it - by waiting too long. (I am having trouble acquiring another caseless tester - which I waited too long to buy - see previous tester summary) The shipping time from Hong Kong to USA was 2 weeks. I have purchased and received several project cases and hope that this caseless tester will fit one of my project cases. Purchased from big-auction-site as a non-auction price item. It tests 7400 and 4000 and 4500 series IC chips. It is advertized as a "Logic Gate tester" and  it displays the pin-by-pin status of the test progress. It ends the test progress by displaying whether the chip is Good or Bad. A nice feature is the display of the chip type/purpose for example 7407 is a Hex Driver and will display the chip's function & purpose. Buttons are labelled Mode UP Down Test. LCD is backlit. Operating voltage between 7-12 volts which allows operatiing on a standard nine volt battery.

I used a 9v battery clip soldered to a DC plug and head shrink tubing for a professional fininsh. This home-made power clip allows this tester to run off one 9v battery. I find that a standard non-backlit LCD screen (non-backlit Sharp model 1602 LCD screen which is a 16 character x 2 rows) will also run on this tester. When I fabricate a case for it - I will make it non-backlit to conserve power.

Chiplist for this tester is located at the bottom lefthand-side of this page in Blue color.

The following is a video demonstration (FLV format video) and summary of features including chiplist (text file)

I have photographed some examples of Lissajous patterns which I have seen on Beckman Scopemate 2. This is not all of the patterns - there are too many different patterns to list. This is just some. The most important one is the vertical line - this means the pin is a dead short. When comparing a good IC to a questionable IC - nitpicking is not how to do things. When a pin is bad - it is blatently obvious that the 2 lissojous pattens are not the same. Or there will be an obvious difference like an extra swoop or squiggle somewhere on the pattern - that is not there on the known good IC.

Also the latching inside of a chip may make the pin you are looking at scratch your head - why is it different this time? Well test it again - this time it displays another pattern or another pattern. My point is some pins show many different patterns depending on their internal latching state etc.

Worn chips that still work fine may differ from the brand new chip but that doesnt mean it is a bad chip. It takes experience to know what is a bad chip and what is a good chip. In summary a bad chip will have an extra swoop or squiggle or will differ in a major way from what it is supposed to look like. Nitpicking small deviation is not what this is about.

I have only shown examples of Linear ICs and standard 7400 and 4000 series patterns here (not every pattern is shown)


Beckman Scopemate 2 and Kikusui COS6100M 5-channel 100MHZ oscilloscope.

The Beckman Scopemate2 is described as an IC tester and component tester in the manual - but it is so much more. It tests pin-by-pin or component by component and outputs to an oscilloscope's X-Y mode to draw the pattern on screen for display. Putting a known good IC chip on one side and a questionable IC in the other side - a pin-by-pin display showing a line pattern can be used to compare whether the good part and the questionable part look the same. If these show a substantial difference - then the questionable IC is bad.

It also tests diodes, transistors, linear ICs, transistor arrays, voltage regulators and other parts. Up to 40-pin chips can be tested. This is primarily an out-of-circuit tester but by using the 2 component test probes - it gives a display similar to a Huntron. I use this setup to fix Huntrons when they are received by me for repair.

Some interesting features are alternating the display back-and-forth between known good part and questionable part. A 1-40 button press selects which pin on the IC is being viewed (see black keys on the tester). A relay click sound is heard as it toggles back between good part and questionable part being displayed. The component leads also allow comparing two side-by-side boards with automatic toggle between views or left board and right board (notice the two banana jacks on each side which is for 2 sets of component test leads) transistors and diodes etc can be inserted into the IC socket or tested via cables.

The jumper wire shown in the above picture must be set to the ground pin on the IC for each IC type. It can be used for 7400 and 4000 series chips and optocouplers etc I like it for oddball or one-of-a-kind chips where there are no specifications on the chip - but I have 2 or more boards which I can probe and compare.

The device under test receives approx 5v AC 300 microamps (less than one milliamp) which is so low that it will not harm CMOS chips.

The displayed grapics pattern is sometimes called Octopus Curve Tracer (invented in the early 1930s approx) or Lissajous Pattern or component tester.

Some oscilloscopes have a component test feature built right in and shows the same on screen pattern- but my oscilloscope does not have that component-test feature built-in. I like my osilloscope alot and 5-channels is more than I use. The X-Y mode draws on screen - I use my X-Y mode for my Beckman Scopemate2 and it draws the represenatative pattern for each component under test. This oscilloscope is very high end in features and using it to display X-Y is a piece-of-cake for this well built oscilloscope.


The manual does not recommend this Scopemate2 for testing electrolytic capacitors or tantalum capacitors. That is ok because I use my Capanalyzer 88A for testing capacitors in-circuit and my BK815 for testing out of circuit capacitors and my DY294 tests the actual charging voltage of a capacitor. Not being able to test capacitors with this tester is ok because I am covered very well by my other testers for the testing of capacitors. I tested quite a few capacitors and some display oval and some display an oval so thin it is easy to mistake it as a line. Some parts of the manual does mention the testing of non-polarized capacitors.

Also the manual warns not to use this for testing live circuits. The testing is performed when the parts, components, ics, board  etc to be tested are not powered up and all capacitors discharged. the manual also warns against prolonged cycling alternating between left and right component testing displays - it says the relay may wear out - so it is best to turn off that alternating feature when not being used.

Calibration and Manual Typo
The manual states that the Volts per division should be set to 5V (probably a misprint/typo in the manual) but this produces a very small mini Lissajous pattern on the oscilloscope screen. I find that I have a better view which more closely matches the manuals diagrams as I set my scope to 2V per division and fine tune with the red knobs for X and Y and also center the image. To calibrate - I use a brand new 2N3904 transistor and 2N3906 transistor and adjust my oscilloscope knobs and controls to match the manual's samples which shows what it should look like. Then everything lines up very similarly to the rest of the manuals samples - including the grid/graticule lines matches the images in the book.


In my opinion this is the best lissajous-pattern-type device for me since it takes up less space and does so much and applies so little current to the device under test. My oscilloscope gets used much more since I have purchased this Beckman Scopemate2 in 2014 (the tester was mfg approx 1991). The Kikusui oscilloscope I have owned for 15+ years purchased used.

The manual was difficult to find and I was fortunate to find a seller with an extra original Beckman Scopemate2 Manual (somehow he had 2ea but one tester) which was more than I hoped for - I was expecting to only find a photocopy - but in fact I have the original manual now. I purchased this tester used and was missing cables and power adapter. I made my own cables and supplied my own powersupply (missing these when purchased). I am using a 7volt AC 300mA wall-type power adapter which I fitted/soldered with the correct plug. Usually wall type adapters supply more than their rated value and this one supplies just over 10volts as measured on my Fluke multimeter. The Voltage regulator inside the Scopemate is a 5v regulator. It runs just fine on a DIY power adapter and cables. 2 of the rubber feet were replaced due to age and deterioration (2 feet turned to sticky goo).

I see that there were 2 identical testers - one made by Wavetek and one made by Beckman Industrial. Both units look identical and bears the name Scopemate 2. I have included a photo of the sister unit as a downloadable file. My unit is the Beckman Industrial Scopemate2

I should have purchased this a long time ago.
For example I have an old power supply which I replaced in an Artiscan 8000C SCSI (Tamarack sister company scanner) scanner and I kept my old nonworking powersupply board (still have this board). I never could figure out which part was bad . Taking out all parts to test one-by-one out-of-circuit was not possible. But in the first hour of receiving this Beckman Scopemate2 & getting this tester up and running - I see that 2 transistors show only short (vertical line) on several legs - in that Tamarack/Artiscan board which baffled me a long time ago. If I had this tester back then I wouldnt have had to buy a new power supply from the mfg. It was easy to spot oddball patterns or lack of patterns for semiconductor components and ICs. Now I dont have to guess or make hunches on which components are bad - and hen desolder to test. It helps reveal semiconductor condition while in-circuit on unpowered boards. Big time saver.

I own 13ea Professional Integrated Circuit IC Testing Machines - Each Tester Tests a multitude of Integrated Circuit chips.

These machines are useful for testing and perform very well. Some chips are unique to each machine - so I have provided columns of data for reference / data.

        

I have also included my own notes so I can refer to this list when testing the chip - for example some chips require the use of an adapter board and my own list helps me when testing.

Some of my testers have "Loop" fuction where they continuously test the chip - cycling and looking for intermittant problems and glitches in IC chips - which helps pinpoint bad IC chips which have intermittant issues. Some tests can take 1 second and other tests 80seconds and other tests can be run continuously for as long as the chip is plugged into the socket.

Some of these testers can identify unmarked IC chips as it compares the chip to its built-in list of chips / databank / database using the "Search" function.  


Why have so many testers?

It isnt sufficient to have just one tester. When I check an IC chip to see whether it is a good chip - I test it on multiple testers - as many as I have that will test that IC. See some testers may PASS that IC chip and one or more testers may FAIL it. Well which is the correct diagnosis? I build a list of FALSE PASS or FALSE FAILS and have a pretty good idea on which ones (tester to ic compatibility list) to disregard for certain ICs as there isnt 100% accuracy in any tester. If ALL of my testers PASS the IC the certainty in that IC is very high. If any of the testers FAIL a chip it may be a weakened or bad chip or borderline pass/fail chip (or a defect in the tester itself where the data was entered crrectly in its ROM or EPROM truth tables) Also each tester has its own threshold for what it considers pass/fail which may differ from other testers' threshold.  ALL are good testers and all contribute greatly to the confidence level in knowing whether the IC under test is a good one and worthy of being used in a circuit.


A blown IC chip will FAIL on all of my testers. Not all bad chips are Blown. Some bad chips are just weak and may actually PASS on some testers. A bad chip will FAIL on one or more testers. Every tester I own pulls-its-own-weight and has caught some bad chips that the other testers didnt catch. That is why I value having as many "second opinions" as possible. Even brand new IC chips - sometimes are defective and should be tested before use. Weakened chips often cause a circuit to cease functioning- a weak chip upsets the math that was used when designing that circuit. Only looking for Blown chips - is not the answer to all repairs. It is important to replace Blown parts and weak parts. It takes skill to know when a part is good-enough. If it fails any of my testers- that IC is not-good-enough - even if the other testers PASS it (With the exception of a known truth table defect with that particular chip/tester.) Each tester has its own testing strategy and parameters it looks for.


You should not look at it as - which tester is the best? ALL testers are good and when used as a team as one tool - can catch IC chips which are bad or weak. All testers use a different testing method and parameters. If I relied on only one tester - some bad / weak chips would go undetected.


The more testers I use - the higher the level of confidence in the diagnosis.


An Analogy of A Drivers License Test - relating this to IC Tester

I'm elaborating on why each IC tester is valuable. And you should not think of IC testers as being better or worse - than each other. I value each and every tester that I own. All of them contribute to the confidence level of that Chip being good.

Lets say that each IC tester is like each test you are given when you go to to renew/obtain your drivers license. You may be given some tests 1. Written Test, 2. Behind the wheel tests A Parallel Park B Seatbelt C Speed Limit D Use of Blinkers D Braking E Merging into traffic, etc too many to list. If you expect to get your drivers license but you failed to use your blinkers - you flunked no matter how well you did on any other tests.

Each IC tester uses a different testing strategy - each maker of the IC tester has his/her own idea of how to go about testing the IC to make sure it works. Lets call IC tester #1 a parallel parking test. Lets say the IC test OK or PASS for parallel parking - is this IC good - probably yes. But I will still test that IC on all of my IC testers on-by-one and every once in a great while - I will find that the chip - that has passed every one of my testers - but one. And that chip FAILS on one tester. So somehow the test that the IC tester gave it - did not hold up to scrutiny. I VALUE THAT - GOOD CATCH and it may be the difference between finding that intermittant or hard-to-find problem. I hope the Drivers License analogy makes this clearer. It is not that the chip FOOLed the other testers - that chip passed the Drivers License Written Test, It used its blinkers correctly, it merged and changed lanes correctly. But it failed when it came time to parallel park. It was a good catch and replacing that IC chip will be beneficial.

Sometime a chip will FAIL on one tester and PASS on all the rest. It is not always on one tester model. Sometimes another model will catch an error. It is always on a different tester. All of these tester pull-their-own weight and contribute greatly to catching those hard-to-find problems or glitches in circuits. I am always on the lookout for a new IC tester to add to my daily-use equipment. How often does this happen - maybe one out of every 200 -2000 chips (as found in used equipment being troubleshooted) and I have tested thousands. I save these bad chips - they are valuable because they can be used to scrutinize an IC tester purchase. So the bad chip that cannot "parallel park" but is able to pass the "written test" and successfully "merges lanes" now becomes a tool to scrutinze a newly purchased IC tester added to my collection. I have about a dozen bad chips like this - all of them trigger a FAIL response from a totally dfferent tester. I mark these "bad" chips so they do not get reused in a circuit. 

If a person emails me or phones me and asks, "so which IC tester is the best one." I'm telling you right now - you missed the point. The point is that all IC testers are good. They must all work together as a team. All ICs must be tested on multiple testers - as many as possible. A good chip will pass all IC testers- uless there is data entry error in that tester for that particular chip- which some of them have this. And I make note of this - so I know when at the results of the PASS or FAIL is due to a data entry error in the ROM of that Tester. I'm calling this "experience" in understanding what is being displayed.

I know of no-one else in the world who does this.


Intermittant chips

When I find a chip that FAILs on that tester - it generally continues to FAIL on that TESTER - when doublechecked or triplechecked. Even more rare is a chip which will give an intermittant error on one tester - and then you ask yourself - hmm thats strange - did I just see that? An example is my ISI SEM Microscope repair notes (click on the link at top of page to see more about this) regarding a Digital Capture Card. If in doubt - replace the chip and make note of it.

My Notes about TTL Digital Logic Chips etc


7400 Series Chips usually have the following ratings and specifications printed on the chip (For example 74LS51 or 74HC85 ...)

STD, L, LS, S, H, C, HC, HCT

Temperature range up to approx 160degrees F


5400 Series Chips usually have the following ratings and specifications printed on the chip (For example 54H01, 54C86 ...)

STD, L, LS, S, H, C, HC, HCT

Temperature range up to approx 300degrees F

(5400 series chips are considered the"military specification version" of the 7400 series family of chips. The main difference is temperature rating is vastly higher and rated to survive in a hotter environment. Not all 5400 series chips are rated at 300degrees F - check the datasheet on that particular chip/mfg as some differ.)




Note 5400 series chips and 7400 series chips are generally interchangeable except for temp range is different. (Some exceptions to this may exist)


Most of my Testers are for Digital IC Chips. I can test a few Analog Linear Chips Also- refer to lists (below).


Some chip mfgs have their own numbering system but the chip itself is compatible with a standard chip model - cross reference to standard ICs.


A few of my testers require adapters for certain chips - but most of these same chips do not require an adapter on another one of my testers. By simply using a different tester for that chip - very few adapters are actually needed - because for that chip - there exists another tester which requires no adapter - in all but a few cases.


While all of my testers test mostly the same chips - there are substantial differences in the lists - some testers skip certain chips. All of my testers have a unique set of chips they test and each one handles the testing process differently. When verifying a chip - I try to test it on as menay testers as possible - noting the result for each tester.


For example chip 75L60 can only be tested on the "Chiptester CT-2" as the test is unique to that tester.  74255 can only be tested on the YBD as the test is unique to the tester. 74H61 can only be tested on the GUT as the test is unique to that tester ...


For example 7400 can be tested on all of my testers


What Do the Letter Codes Mean?

74 = Standard TTL

74H = High speed TTL

74L = Low Power TTL

74S = Schottky TTL

74LS = Low Power Schottky TTL

74AS = Advanced Schottky TTL

74ALS = Advanced Low Power Schottky TTL

74C = Metal Gate (Pins are compatible with TTL)

74HC = Silicon Gate High Speed (Pins are compatible with TTL)

74HCT = Silicon Gate High Speed (compatible with TTL)

***Some of the above may not be interchangeable and

check tester before plugging in as some may not be

able to be tested on all testers


I have included a Bug and Glitch list of IC chips which confuse the testers or give False results. False Pass or False Fails and notes regarding special circumstances- see the bottom of this page - at the very end of this page on the right-hand side. Viewer/reader contributions to this growing list is welcome. It is not my intention to knock any tester. I value the "second opinion" of additional IC testers as it adds to the level of confidence that the test results are indeed correct. Knowing which testers give questionable or incorrect results is important. None of my testers are perfect - all of them working together - allows the confidence level to be very high - in obtaining test results and identifying bad parts. It is not intended to say one IC Tester is better or worse. All of them are very good. I'm glad to have them all.

User Manual for GUT IC Tester is here

This tester's version is 2.16 and is slighly different than this manual.

For example my tester does not test ULN2003 and various ULN chip as I cant find it in the menu. The pdf file is for model XXXXA where my tester does not have the A in its model number. My hunch is the A stands for a few analog chips which were added.

One of my other IC testers (TSH) can test the ULN chips-  dont worry - I can test ULN chips on another tester.

This tester is very fast - performs searches and tests quickly.

Notes

My tester is Vizatek model VZ-4 and looks to be similar or nearly identical to Kitek DICT-01. I opened up my tester and found the circuit board which states "DICT01" on the circuit board.


Never connect AC/DC adapter to this IC tester. Use 9V square battery only. A look inside the unit reveals that the power jack is unregulated. Even though there apears to be a voltage regulator present - trust me it is not regulated from the jack. Use of battery will not light the backlight. Use of power jack will light the backlight.


Never use the power jack. I suggest putting a sticker over the power jack so someone doesnt accidently plug it into a ac/dc power adapter.

Notes

My IC Tester is "Modular Circuit Technology model MOD-HIC IC Tester" and is similar to "Ming HT-21 Handy Tester" or "Hi Lo Systems Prufer-20 Handy Tester" which looks to be a nearly identical or very similar tester.

This tester is very fast - performs searches and tests quickly.

TESTER #6 "TSH"  


List of IC Chips I can Test

This tester does not have a list of each and every chip that it can test in the instructions. Instead it lists general categories of chips such as 7400 series and more which are listed below. Using the IC Tester's menu - I have listed each and every unique chip that it specifically shows in the device's LCD menu.



7400 Series

Notes:

This tester is very good at distinguishing between HC and LS 7400 series chips. It will fail a LS chip if tested under the HC mode. It will fail a HC chip if tested under the LS mode. LS is low speed and HC is high speed and this tester can test high speed and low speed speed paramenters very well.

This tester also tests zener diodes and gives the measured voltage value which is a very rare feature. This is much better than other common semiconductor testers (most of these cheap semiconductor testers are sold online as a bare pcb - I have one too) for zener testing because the competition products give the breakdown voltage which is of no value. This IC tester's zener test gives the actual voltage value which can be compared to specification sheets of the diode to determine if the zener diode is within tolerance. Zener diode test is performed in the righthand side of the IC socket in the lowest 2 holes. Zener function "ZD" is selected from the menu.

This tester can also test optocouplers/opto isolators having 4 pins. The 4-pin IC is placed in the socket at the lowest position - in otherwords - furthest away from the zif socket's lever. Selectr "LIGHT" from the LCD menu for optocoupler testing. Optocoupler compatibility list is unknown.


This tester is not good at searching for 7400 series chips in its search function. Manually searching sometimes produces "not supported' which means the chip I'm looking to test is not in the internal device list (instructions lack a list of chips). It is quite good at auto identifying analog chips and the list of chips shown in the menu by automatically searching.


I am starting to build a DIY chiplist for this tester TSH-02F as no chiplist was included in the brief instruction sheet. I am building this list from scratch by going through the menu chip-by-chip and seeing if that number produces a "not supported" - or "fault" if it says fault with no IC in the socket that means it is a testable chip. if it says "not supported" that means it is not a testable chip - according to its built-in chiplist.

7400 LS and HC (Both Lists in this machine are the same)

(this growing DIY chiplist to be continued as I have time)


This tester does not come with a list of chips that are testable - instead the tester documentation gives broad families of chips which it can test - without listing individual chips in that documentation.

I have found through hands-on experience that certain chips test fine and others display "not supported"

SN74LS169BN
SNF169PC
SN74154N (to big to fit in socket)
SN74LS03N - "fault" LS and HS model may be reversed

PC817 Opto 4-pin chip lowest pins on socket (menu=Light install backwards "0.17V" upside up "Open" partial test

Transistor test (Menu = TR) only identifies it as PNP or NPN and gives pin orientation but does not give value or show leakage - only pinout and PNP/NPN. Use last three holes on socket to the left side.

Zener Diode test - use lowest/last two holes on righthand side of socket. Menu = ZD. Test rightside up and backwards manually flipping the zener diode.

This tester is a very popular item at a very inexpensive price. It seems that the hardware is able to handle both TTL digital chips and analog chips as there are a few analog chips in its internal library. I hope that the popularity of this tester inspires the mfg to come out with a Linear IC tester version or users figure out a MOD to add chips to the internal list. The current price for this tester in 8/13 is approx $60 although I paid double that for mine since it was purchased before USA online release and I purchase mine from SIngapore and had it imported.

The lack of a chip list in the documentation - and the usefulness of this tester - inspired me to create this list. Reader/user data to be added to this list is welcome and appreciated. I have tested many hundreds of chips - most chip models - with many duplicates of same chips models - the above lists reflects all chips I have tested on this tester - as I kept detailed notes.

Note Big-auction-site was swamped with the TSH-02F "yellow sticker IC tester" just like mine that I purchased from SIngapore. The price on big auction site was between $55-75US depending on the seller sometimes with free shipping and sometimes not. After a few months another similar tester model TSH-06F the "blue sticker IC tester" at approx the very same price was competing. It is my hunch that these 2 testers are functionally identical or extremely similar - except there are 2 extra buttons on the blue tester. It is my hunch that these 2 extra buttons are for scrolling through the internal chiplist. My yellow tester requires each and every chip number to be entered manually.
So the scroll buttons would have made my building of this DIY chiplist a whole lot easier. Thousands of keypresses later - I see that my buttons have no sign of wear and they all function just like new (7400 series chiplist done as of this writing).

Update 1/25/14 I have received user confirmation that the TSH-06F "Blue sticker tester" is functionally the same or very similar to the yellow TSH-02F. The blue tester uses 2ea AA batteries while the yellow tester uses 1ea 9V battery. The blue tester has "O" key on the keypad for on/off. The yellow tester is powered on by pressing "enter" key and then turned off by selecting "off" in the menu. The blue tester has a "P" key which is undefined or undetermined what it actually does or doesnt do. No instructions came with the blue tester - as referred to by another user. I myself have the yellow tester and have posted the instruction sheet. These testers are so similar that this instruction page is applicable to both blue tester and yellow tester. If anyone figures out what the "P" button does - let me know. This insight from another user also figured out that the TL074 can be tested on the TSH model testers by using TL084 but inserting TL074 IC.

 

TESTER #7 "ICT-101"

My MSI Micro Sciences ICT-101 tester is a "standard" model and has the standard edition chips list in its internal ROMs. The 2 extra upgraded ROM chips are not installed (2ea empty sockets U10 and U13). I am only listing the standard list of chips here. If I can obtain the extra ROMs from a reader - then I will add those extra chips later to my list.

For right now - these are the chips I can test with this in-circuit IC tester with Standard ROMs.

I have put the add-ons chip list here - on this downloadable text file. I would appreciate if someone has these upgrade ROMS (any version) if they can provide the BIN or Hex file for me. The existing standard ROMs are 2732 and I would assume the upgrade ROMs are also 2732. I would like to be able to test the chips in this list - but alas I need these two upgrade ROMs to do that. I'm still very happy with my tester- but the upgraded ROMs would double my in-circuit capabilities.

The following is not intended to be a cross reference.

This is intended to show what the LCD displays when a particular chip is under test. There are many variations of IC numbers. Also some of these are for the upgraded ROM set - for which I do not have this installed in my machine, I have the standard ROM 204 C version. I do not have the extended 205 ROM. I have not tested all chips on this list but I know that many I came across in my repairs have displayed on LCD as shown.

6840             Tested 3ea MC6840P and 2ea MC68B40P chips (from big auction site seller) and they all "FAIL" I dont think this tester can test MC6840P series of chips. The motorola chip MC6840P is a programmable timer. It is possible that the 6840 the instruction manual lists is referring to the 6840 Peripheral Interface Adapter chips 5V 16-Bit 6MHZ DIP-28


Z80CTC (Enter 802 on YBD Tester for Z80 processor test and also Code VCC24 - not that the z80 ctc chips have a difefrent pinout than other z80 chips. The CTC version of z80 chip has the vcc +5v on pin 24. This test is only for CTC version Z80 processor IC or Z80a processor IC. The word "CTC" must be printed on the IC - otherwise dont test it.)

TESTER #4 "CT2"  


List of IC Chips I can Test with this tester - notes show

which designations of chips (undesignated chips are

noted as STD which means the chip is marked 7400 for

example with no letter in between the 74 and 00.

Designated chips have a letter in between such as LS

For example 74LS00. This tester requires an adapter

socket for certain chips which is noted in this llst. 


The last indicator on each line shows the correct

display for a good chip. For example when testing a

74LS00 chip the display shows 00 which happens to

correspond to the chip number. Not all chips have this

coincident of the display matched to the chip number.

For example 74H140 shows 20 for a good chip.

List of IC Chips I can Test


List of IC Chips I can Test with this tester- notes show

which designations of chips (undesignated chips are

noted as STD which means the chip is marked 5400 for

example with no letter in between the 54 and 00.

Designated chips have a letter in between such as LS

For example 54LS00. This tester requires an adapter

socket for certain chips which is noted in this llst. 


The last indicator on each line shows the correct

display for a good chip. For example when testing a

54LS00 chip the display shows 00 which happens to

correspond to the chip number. Not all chips have this

coincident of the display matched to the chip number.

For example 54H140 shows 20 for a good chip.

TESTER #8 "LIC"


List of Linear/Analog IC Chips I can Test with

LIC Portable Linear IC Tester


Notes: I found 4ea extra ICs in the Menu that are not in the chiplist booklet which came with the tester. CA3401  LMC660  CA723 LM723 are in the menu and are testable ICs on factory stock ROM version 1.1 which my tester came with. The chiplist in the menu are not in alphabetical order. And is not in numerical order so it takes alot of effort to scroll through the built-in chiplist using the menu. I'mgladit has a very efficient fast "search" function which identifies chips instantly. Pressing  the "Type button & Arrow Down buttons" simultaneously turns the tester off and is not written anywhere on the unit itself how to power off.

TESTER #11"ChipMaster"


List of Digital/Analog IC Chips I can test w ABI CMC ChipMaster Digital IC Tester (non RS-232 interface model) This is a hand-held tester that is an early model and predates the "pro" series and lacks a RS-232 port.

I dont know if this list and notes are applicable to all models of ABI Chipmaster - so this list is for my tester and may not be applicable to the readers tester.

Bugs and Glitches Notes:

This section is a compilation of errors and possible errors found within the testers.

I have personally found these errors in testing large quantities of IC chips and will list findings here. Reader contributions to this glitch and error and bugs list are appreciated. Knowing which test results to ignore is useful - because false FAIL or false PASS infrmation given by the tester - is a hinderance to repair of a device. Knowing which chips cannot be tested ona tester - is valuable information.

These are in no particular order or sequence. This is by no means a complete list - only the ones I have found so far-

I have tested many hundreds of chips - these few glitches are listed here which I have run across. These testers test 99% of the chips properly - so dont take this information in the wrong way. ALl of these testers are good - with a few internal data errors within the tester.

-----------------------------------------------------------------------

SN74LS169BN - always fails on YBD tester

SN74LS133N - always fails on GUT tester

SN74LS03N - always fails on TSH tester - I tried this very same ic chip using the HS mode and it passes- it is possible there is an error where the HS and LS testing modes are reversed within the tester.

SN74LS163AN - always fails on VZ tester

SN74LS153N - always fails on VZ tester

S 74F109N - uncertain whether TSH and VZ testers are testing properly?????? varies with brand

S 74F350N - always fails on YBD tester

74F189PC - always fails on YBD tester

SN74ALS576AN - always fails on GUT tester

74F169PC - uncertain whether YBD tests properly ????

SN74LS168N - uncertain whether YBD, TSH, VZ testers are testing it properly????

SN74F109N I purchased 5ea from big-auction-site seller and this chip has caused me alot of uncertainty on whether these are good or bad chips. My 560 IC tester says that 2ea chips are good and 3ea chips are bad under version 3.00 ROM. Under version 2.50 ROM before I upgraded ROMs - it would intermittantly pass or fail. I will need to review this model of chip as this new ROM version 3.00 may finally clarify which is a good or bad chip. Several testers have a hardtime with this chip which has a "F" and I think the testers are expecting to see "LS" chips. Some big-auction-site sellers sell bad problematic chips.

YBD Tester Fails all Motorola MC6840P series chips. It is possible that this tester is not for the MC6840P chips at all- it is possible that the tester is for the PIA 6840 chips. The instructiions simply list 6840 which is vague as far as which chip it is referring to. Further notes above next to the YBD tester chip list next to 6840 - see above for more info.
