Yes, but Zero settings on PicoScope 6 are valid only during its operation. When restart PicoScope 6, the settings are not saved. That is, the offset again 3 mV.

Hello!
I'm engineer. I am engaged high-voltage equipment measurements.
I have 1 question.
PicoScope 4227 has a zero shift (about 3 mV).
I think that one of labeled elements (see photo) is used to adjust the zero offset.
If so, please indicate which item it is.
Thanks.
