[volt-nuts] Fluke 5200A instability... A resolution...

[David C. Partridge]

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.

Cheers
Dave

:

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.
