I have NOS 3000uf/50V capacitors & germanium output transitions (34425 & 2N2147). Will this tester accurately asses the viability of these devices?

The tester will measure your electrolytic cap's capacitance and esr but not leakage. It will test bipolar transistors and identify E B C leads and PNP or NPN, and measure beta gain and E-C forward (on) voltage drop.

The one that I have is reliable and reasonably accurate down to about 80V. Below that voltage it rapidly becomes inaccurate and the display flickers. I do not know the maximum voltage. (I tested it with a variable-voltage transformer.)

will not test caps in circuit, you need an esr meter for that. the newcason is good for out of circuit. decent meter for the price. pretty accurate.

I use it to detect bad magnatrons and transisters, and it will show a difference of 1 ohm, the only one I have that will go that low.

I haven't had a chance to test the tester out. There are sites on the internet you can check on and I tried to find some instructions on this - sorry.

I hooked up the capasitor as the positive and it works really well. Havent had any problems with them i have two running and there amazing.

Personally I would try the one by Solrus which one reviewer said worked with his Trane (misspelled as Tran). This one worked on a very old GE but it was listed. I wouldn't trust any of the claims for "more" unless your specific brand is listed. Sorry.

I don't know the difference between old and new current readouts ..... My unit uses current transformers

Hello, This is a great analog meter which is perfect for testing all different types of diodes but not a great tool for testing capacitors. I would highly recommend a ESR meter for testing Capacitors. Hope this helps.

Nhaps this device is only for test Capacitance from a Capacitor, is not for test motors, please sorry my english..

Yes. Keep in mind that it's not an advanced tester. It only tests the pins in sequence to see if each wire is connecting. If a light doesn't show, you have a bad cable. It doesn't test things like capacitance, attenuation, crosstalk, and the like.

Get the voltage and polarity right and you should be ok. Just be careful not to fry it.

I have two outputs that are not terminated and it seems to work fine. I have been using the device for a couple of years now.

Yes, it will read capacitance up to 20 Microfarad (20uF). However you must disconnect/remove from circuit the capacitor you want to test (or at least one lead disconnected). If you try reading a capacitor while installed in a circuit you will get erroneous results.

I have only had the chance to use this tester 2 times now. It seems to work quite well if you can find what the codes mean. As far as I know this should work on many different types of main boards. One of the neat features of this is that also serves as a voltage meter. I could see this product going much further if the developer would continue their work.This website can be very helpful. Pick the bios type from the side. http://www.bioscentral.com/

Positive. I was using one of these about a month ago and tested it with a multimeter. The center was positive and outputting around 9.3 V
