Hi everyone.
I have a CHY 24c LCR meter that I bought used. However, in 200pF capacity mode, the screen does not appear as zero. It shows a value of approximately 5pF. When I turn the adjustment pot, I can reach this lowest value. The measurements are correct, for example a 1pF capacitor appears as 6pF. (5+1) How can I solve this problem? Does anyone have documentation for the device?
Thanks.
