    Transistor Tester Help

    I bought a transistor tester of ebay, shipped from china tester pictured below -




    The unit turns on and gives me the splash screen + the firmware number.

    I have tried several capacitors in the device and they are all "unknown or damaged" the meter is supposed to be able to test ESR. These are brand new out of packet capacitors

    I have spoken to the seller and they claim the positioning of components in the test holes is arbitrary.

    Does anyone else have one of these? How do you test componenets

      try a capacitor between pins 1 and 3 and see what it reads

                  I agree.
                  It is probably the same as this unit form the same seller.

                      how can i test individual leds without tester
                      by nubinator
                      Hello I have TCL 65S4 and it has no backlight, seems common problem on this tv to have bad LED's. I have no tester though I thought I could just test each LED with 2xAA batteries for 3v but it doesnt light up at all?
                      I saw a vid with LED tester on this TV and it had 130v for 1 good line which is 24 LEDs does that mean it needs around 5.5v per LED?

                      How Can I test PWM DM0365R?
                      by chth96
                      Hello
                      I have power adaptor(220V/input, 12V 1.2A/output) which has symptom of fluctuating output DC voltage between 11.5V-12.2V.
                      So I opened its plastic case and when switched it on, I heard constant tik tik sound from inside its PCB.
                      I measured DC voltage between negative and positive pin of the largest capacitor(400v 10uf) and it was measured contant 300V.
                      I also measured ESR value of all capacitors and I noticed that one of capacitor(KMG 16v 470uf), which located in the secondary side, have high ESR value(10 ohm),So I replaced it with same specification NXH capacitor....

                      This is another battery testing machine that needs to be modified for the cooling fans because these are noisy but not as bad as one of the other battery testing machines that I had modified recently because of it being too noisy

                      The battery testing machine is going to get two temperatures controlled cooling fans like one I put in the other battery testing machine I just have to remove the temperature sensor and relocate the temperature sensor to one of the heat sinks and put one on the other heat sink so the fan speed can be controlled by temperature

                      test active pfc power with lamp test
                      by khelane
                      Hello
                      I have a big problem and that is that in some cases when repairing active pfc power supplies I cannot work with a test lamp. I can only get help with 5 volts standby and for starting and starting I have to work without a lamp and this way there is a possibility of parts exploding and other parts being added.
                      Sometimes with a multimeter test the problems can be reduced to some extent, but I had several cases that had to be tested on and online and recently two varistors exploded. They had terrible resistance because the power supplies were over 800 watts.
                      Is there a way...

                      Mats / mods: detected and repaired GPU fault. Cant seem to test after!
                      by chronic519
                      Hello.

                      GPU came in, green lines. Spent lots of time using to get the Mats / mods drive working (found on youtube).
                      Found issue with a RAM block
                      Replaced, green lines gone.
                      Trying to test again, assuming getting the false positive. Originally had over 1K on a single bank. Now getting tosses low between banks.
                      Used a good card to test and same results low errors 32+.

                      I am just search for some form of command to do a full test on the GPU.
                      I just ran the mats command with my good GPU and passed after roughly 40 min.
                      The repaired one, ran...
