Re: esr or cap tester
Aloha RusMike,
The meter is fixed, simple enough, got an 1 ohm chip resistor from an old board, I usually throw those out but I was hanging on to this, I should start saving them even though they are no good
The new resistor is 4 times bigger but I soldered one side directly to the red probe, it works!
Thanks!
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: esr or cap tester
Yes, R1 is not 1 ohm, it's like .14 or something like that. Now I have to hunt down one of those, it may be hard to find in Honolulu; question - will it void the warranty if I do my own repair???

Re: esr or cap tester
Anyone knows how I can get my ESR-Micro V4.0s for warranty repair? I bought it from PRC68.com last month, I was checking on a power supply board of a plasma TV a few nights ago and one of the capacitor still has charge inside and it sparks and the meter is not working correctly anymore. The board had been disconnected from the power source for over a week and I'm surprise it still holds charge.
PRC68.com said they don't do repair. It said it has a 1 year warranty on the website.
I can still turn on the meter and show the voltage of...
