I have an Extech 380652 that seems to work well in general but has
an approximately 0.06 A offset in the AC Amps mode on the 20 A range.

The user offset adjust pot only works on DC Amps.

Does anyone know if any of the 3 pots inside are for the AC amps offset?

Thanks!

Not just extraneous pickup from building wiring maybe ? Probably not, but
just a thought ...

The op should be lucky its down that low on AC.

I have an extech my self (different model), that seems to have
a undocumented feature that appears to calibrate the AC mode of the
clamp when I hold down one of the buttons for like 4 secs or more.
