G'day,

I've recently acquired an old bench multimeter, a Fluke 800A.

On the most sensitive AC-range (200mV AC) it seems to 'overflow'
(displaying 1999mV) when leads are attached. Is this normal behaviour
for this equipment? When shorting the leads, it displays correctly. On
the 2V AC range, it displays about 0.3VAC...

Is this because of RF interference in the air (but why don't my other
multimeters have it so badly?) or is it in need of repair?

If it's repair that's needed, any idea where to start looking? Or, does
anyone have a schematic or service manual available for this Fluke
800A?

Sincerely,

Peter,
