Hello !
I got a couple of old Fluke 8000A DMM's and they are fine except for a common fault they share: 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 !
