Wie ist denn der Stand der Dinge?

Wird das Gerät von Euch oft verwendet? Lohnt es sich?

[christianw.]

Ich nutze es gelegentlich für L,C und Dioden, vornehmlich bedrahtet.

[voltwide]

Wenn es denn ein vernünftiges Gehäusekonzept gäbe, wäre die Sache wirklich rund. Ansonsten benutze ich es gelegentlich für Elkomessungen mit ESR, bedrahtete Transistoren und Induktivitäten.

[madmoony]

Ich für Elkos,und da der ESR.
Spulen für Frequenzweichen....eigentlich im Schnitt einmal die Woche für einige Teile.

Ja. Eben. Da scheint die "normale" Transistortester-Funktionalität drin zu sein und die Chiptesterei (auch OPVs) draufgesetzt worden zu sein. Deswegen meinte ich ja "Man scheint weiterzumachen... "

[christianw.]

Glaube ich nicht, das Gerät basiert (m.E.) auf einem völlig anderen Ansatz. Wir haben so ein "ähnliches/älteres" Teil an der Uni. (Englisches Modell)

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
----------------------
CMOS 4000 Series Chips
----------------------
MC140 Series Chips

(Enter all these dropping off the MC1 for example enter MC14000 as 4000)

----------------------
CMOS 4500 Series Chips
----------------------
CMOS MC145 Series Chips

(Enter all these dropping off the MC1 for example enter MC14500 as 4500)

-----------------------
HEF400 series

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

Misc listed in LCD Menu

LM324
LM358
LM339
LM393

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.

(my note: 7400 series done 12/30/13)

(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"

"Not Supported" Chips which I personally tested

SN74LS169BN
SNF169PC
SN74154N (to big to fit in socket)
SN74LS03N - "fault" LS and HS model may be reversed
NTE74LS03 - "fault" LS and HS model may be reversed
S 74F377N - "fault" Not sure if works?????
SN74LS279AN
SN74LS189AN
SNF189PC
SN74LS629N
SN74LS75N
SN74ALS756AN
S 74F350N

Linear IC/Parts Testing Notes
LM339 - place chip at top of socket pin 1 furthest up

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.
