    ESR-Micro V4.0 does not measure anymore

    I have got this ESR meter a few years ago, barely used it and now when I need it, it won't even turn on.
    The switch used to act up. I had to push it multiple times, until it would turn on.
    I'm about to get a switch and I will replace it.
    I have started it up, by shorting the switch pads. It starts up just fine, but it does not measure anything, or it won't calibrate either.
    The wires are OK, the protection diode checks out OK.
    I'm at a lost here, on what to do next.
    Batteries are good as well.
    Any help would be appreciated. Or recommend something else to buy.
    I also have one of those cheap Chinese ones, with a black display, that it was a kit. It works, but I don't know, if I can trust that measurement.

    the chinese ones are fine if you calibrate them after you get them.

      They can be used in circuit?

        as much as any - which is questionable.

            The only thing that I can do, is to replace that switch.
            It was acting almost from the beginning.
            At the moment, I only have vertical ones, I will solder one in for testing.

              820-4924-A Runs suspiciously slow - what could you measure?
              by pb1911nt
              Hi

              I have now a 820-4924 (with a i7 and 16GB).
              I would like to get the device working again for me.

              The Problem is the Device comes to me with a "dead" ssd. I tested on a other 820-4924 (i5-8gb) board and the MAC OS Installation stopped working with this SSD.
              Well i hope/guess its was a easy peasy Fix - New SSD And its working again.. But No!

              I don't know exactly how the procedure should start. But the LCD panel goes dark - then the "chime"(?!) sound comes and only 2 or 3 seconds later the apple comes.

              it doesn't...

              How to correctly measure a mixed low&high current
              by edugimeno
              Hi there!
              Im trying to determine the consumtion rates of a module Im testing. Particularly it's a Decawave DWM1001 module, which is expected to use around nanoamps during normal state so a LiFePo4 battery should last months

              This module has peak spikes of around 100mA once a second, while the TX module is active, and then goes to sleep for the rest of the time (this is when the uA rates are expected)

              But I'm having issues to measure this current.

              1.-Using a multimeter. Obviously all I see is values jumping all the time, as this is not expected...

              Good morning, everyone!
              I've gotten my hands on a few laptops with various defects because I want to get more involved in repairing electronics.

              First up is a Fujitsu Lifebook U7511.
              It won't turn on anymore and doesn't respond in any way when you plug in a power adapter.

              PS5 Dialog DA9081 in power on measure pin EN with 0.5v
              by aandrade
              Hi all,
              According to the image, pin EN should be 3.3V, and I currently measure 0.5V when turned on.
              Does the 3.3V come from another line or is it generated by the DA9081?
              Thanks!...

              Power DeWalt 12V laser measure from power supply
              by dansity
              Hello,
              i got a Dewalt laser measure which uses the 12V batteries to operate. The laser measure is faulty and I want to attempt a repair, never fixed such thing before. You might see a different topic if I fail with the repair
              However I do not have dewalt batteries nor want to buy one for 140EUR as the laser tool might have some chance that it is very hard to repair or unrepairable.
              I want to power it from my PSU.
              The tool has 3 input pins, on the battery it is marked with B-, B+ and ID/TH.
              i want to know what is the third pin exactly and what do I need...
