Tech Note 135 Detail

Can not zero

Affected Products:

ES-9054B Electrometer

Problem/Symptom:
I can not seem to zero my electrometer. What can I do?

PASCO Solution:
If the meter can't be zeroed using the zero adjust knob with the zero switch set to zero lock, the MOS-FET has probably failed.

You can order a replacement MOS-FET from PASCO scientific. The part number is 422-001.
