I already replaced the trimmer with 220 ohm, metal film, 1% tolerance but the 0X0010 appears at 1.30 ohm, is this normal?
another question please, I asked can I connect DMM directly to ESR meter while I do full calibration?
I saw your pictures I think you connect DMM (in resistor measure) directly to ESR meter while you calibrate it.
Or I must disconnect trimmer while measuring its resistance….
Thanks a lot....
