Hi,

I have 7 8600a here with the same problem, several mV Offset in the
200mV AC range which leads to severe offset in all mA AC ranges (3
digits). DC ranges are fine.

I have more details if there's someone out there with experience with
the 8600a. Just can't seem to find the fault. On the output of the AC
converter i see a difference between output, and AZ out, with shorted
input, which causes the offset. But more details if there's actually
someone who knows about the 8600a.

thanks

ST
