Chuck I so feel for you one this one. I almost went down the exact same rabbit hole about two years back when I didn't set the AC Filter to ON on my 7081.
Luckily I didn't get very far down the "my 5200A isn't working" track before I was reminded by a friend that I needed to turn on the filter for <400Hz signals.

A resolution... : Doing something that comes hard for me, I pulled out the instruction manual for the 3456A, and read through the operating instructions. The HP3456A is not specified to operate below 400Hz AC unless the filter button (that I never use) on the front panel is pressed. I pressed the filter button, and the meter fell into line, and read a consistent, and fairly stable value. _______________________________________________ volt-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts and follow the instructions there.
