Fluke 8000A problem: saturation at 1V
 

Hello !

I got a couple of old Fluke 8000A DMM's and they are fine except
for a common fault they sha in the 2V range, they display correctly
up to approx 0.8V, above that the output becomes nonlinear and
saturates at approx 1V for 2V input. Funny thing is that all other
ranges (0.2V, 20V...) work fine.

I assume some protection device (diode?) has gotten bad - does anybody
have an idea how to repair this ?

Thanks for info !

This is all supposition, but I'm not stupid.

The 2 volt range on some Flukes is the same range as the 2K/diode
range. This is shared with no other range. Perhaps this can be a hint.
Also, when in 2K/diode mode does it read oveload, or something else ?
These matters are primal to resolving this.
