    Esr meter.

    I bought one of these meters on eBay, because I've seen you guys mention it, and thought that it would come with some instructions but it didn't.
    Does anyone know where I can read how to use it? Or if anyone here can tell me how?
    Thanks.

      Re: Esr meter.

      It was listed as an esr meter. There is a setting that says esr.

            Re: Esr meter.

            You don't need instructions.
            Put a capacitor between any two of the 3 leads and it will test them
            Put a resistor between any two of .......
            Connect all 3 leads to mosfet / transistor and it will test them and should show you the pinout on the screen.

            The ESR function is not great and I prefer to use the Dick Smith ESR meter.

            Edit
            Just taken another look at your pictures and it says C+ESR so I'm not sure of the other functions I mentioned, but you can try.
            You can connect the item for testing between Pin1,2 or 3 on the IC socket if not using the leads. All the 1's connect together, 2's connect together and 3's connect together.

                Always fully discharge the cap before you put it into the meter.

                  Re: Esr meter.

                  Thanks budm. What is a good way to discharge one quickly?
                  I just tested a 450v 100uf capacitor on a sharp psu/inverter that you were helping me out with.
                  Is this a good reading or bad?

                    Re: Esr meter.

                    This is the type I bought and it's been well worth the money especially for testing transistors and mosfets but as I said earlier it tends to read ESR higher than when I use my Dick Smith tester.

                      Re: Esr meter.

                      The main filter cap is usually not low ESR type, that is pretty good ESR reading, most concern on that cap is the ripple current spec.

                        Re: Esr meter.

                        Sorry guys, I know I am probably driving you nuts, lol.
                        These aren't questions about a specific display. I measured to mosfets from said psu, they are the same, the number on them is K4096.
                        They are still in circuit, so that could be the problem, but should they not have the same measurment?

                              You should learn how to test capacitors and read the data sheet on each one before asking what the esr should be. The data sheet will say so lol

                                    An ESR meter can be quite a handy device for quickly checking capacitors intially in circuit which you can do with the Dick Smith/Bob Parker ESR testers.
                                    As has been said many times on the Forum, the capacitor may look good, measure close to it's value (out of circuit) but have too high an ESR. It's a very quick way of checking if you suspect a capactitor fault.

                                        i have posted a lot on that model - it's more acurate than people think if it's calibrated and the software is not ancient.

                                        read these threads.

                                          Is it possible to test small ceramic disc capacitor with analogue meter?
                                          by chth96
                                          I read EBOOK of Testing Electronic Component and found that

                                          "In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
                                          Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
                                          It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."

                                          Backlight strip quality, Amazon vs Ebay vs ShopJimmy. Is there really a difference?

                                          Hello everyone!

                                          Recently I've noticed that some ShopJimmy backlight strips don't have double-sided tape installed upon them when an application calls for it, and I must purchase the tape separately. In a recent chat conversation with a customer service agent I told them if this tape wasn't applied when it was called for I would begin to consider ordering my backlight strips elsewhere. It looks like this time may have come.

                                          I recently got a TCL 65S4 with bad backlights. After looking at the SJ listing here: https://www.shopjimmy.com/tcl-jl-d65...365as-m-led-ba...

                                          lowest current galvanometer/analog meter (passively powered!)
                                          by eccerr0r
                                          Most analog meters are actually current driven - a current is needed to deflect the pointer full scale. They can be lots of different values. There are ones that can take several amperes to swing the pointer as they have internal shunts.

                                          On the other hand there are many that are rated in microamps for the intent that they draw as little power as possible from the devices under test. Some are 1mA, 500µA, 200µA, 100µA, and the ubiquitous 50µA frequently used in analog VOMs. There are even 20, 25, 30 µA and even down to 10µA. Been collecting a bunch of different ratings and...

                                          Changing the scale of an analog meter
                                          by jorpec
                                          Hi

                                          I want to change the scale of an analog meter, to monitor the charge of an li-ion single cell, so the needle at the end would point 4.2 volts and the 0 on the meter would point 2.5 volts or so, i tried to add diodes or a zener in series with the meter but the changes of the ambient temperature also changes the voltage value on the meter
                                          I wonder how i can accomplish this so the meter would be precise at any temperature ?

                                          Thnaks

                                          How an incandescent light and a ESR meter ** friend**have a machine blowing fuses
                                          by sam_sam_sam
                                          About a month ago we had a transformer jumper wire that burned in two different places between two transformers caused over $200 thousand dollars worth of damage to VFD drives at least 10 of them and a memory card and quite a few power supply as well

                                          Now we have most of the equipment that got damaged back up and running except a feeder that has issues and we are waiting for some parts for

                                          Now we also have another piece of equipment that was blowing fuses on the 110 volt controller switch circuit with the “E” stops and one switching power (24 volt) supply and a transformer...
