    My capacitance Meter

    This is the meter I use to measure capacitance. I have found it to be quite accurate. I appreciated that it had a setting for over 2000uf. When I measure capacitance of new
    low-ESR, high grade caps I get readings that agree pretty closely with the spec sheets.

    I measured a bunch of Sanyo caps tonight. I generally find that Sanyos are very close to the labelled capacitance, typically about 1050 for 1000uf.

    At any rate, it's easy to spot fakes or dried out caps with this. Comments away. It came with two very nice probes, not shown.

    Re: My capacitance Meter

    Even though it has a model number starting with HP I take it that's not actually made by Hewlett Packard?

      Modification of a Fluke multi meter that uses three AA batteries to use a 14500 lithium ion battery
      by sam_sam_sam
      I have had with regular AA batteries that leak this meter is expensive new I already replaced the battery battery clips once and the same thing happened again and I am tried of so it is getting modified to accommodate lithium ion batteries that are the same size excluding the positive terminal and removing the battery clips I will have enough room for the BMS protection board

      I going to put 3 lithium ion battery in parallel with the BMS protection board and a way to charge the battery externally and heat shrink the battery pack and use a JST connector so I easily remove the battery...

      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 ?

      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 ā€œEā€ stops and one switching power (24 volt) supply and a transformer...

      Yamaha PASC5 X0S-00 E-bike charger 42V only providing 12 V
      by MrBojangles
      Hey Guys!

      Hoping I can get some help here. I have a e-bike charger with 4 pins on the output. It has a light but the light does not turn on.

      When I check the voltage on the 4 pins on one of the pairs I get 12 V. On the other pairs the voltage keeps changing.

      Nothing looks damaged and there are no shorts on any of the capacitors. I've ordered a ESR meter to measure the capacitance of the capacitors but it will take a while for the package to arrive.


      Any tips?

      Thanks

      Sacon FZ revival experiment
      by momaka
      So after using capacitor bungs to repair the rubber feet on two laptops, shown here:
      https://www.badcaps.net/forum/showpo...&postcount=548
      … and here:
      https://www.badcaps.net/forum/showpo...&postcount=585
      … I was inevitably left with some paper rolls and cans from the Sacon FZ capacitors I “sacrificed”.

      The paper rolls from these Sacon FZ caps looked absolutely bone-dry. The idea then occurred to me: what if I put a few drops of water on there? How (if at all) would that affect these already-failed capacitors?...
