Noob here, just bought a nice clean Fluke 8800A from ebay… Just powered this one up and before I even get to making a reading, there seems to be an issue. On DC 20V range, the display starts at -0.0000 but immediately starts counting in the negative direction without stopping, about .005V per second. Does this problem sound familiar to anyone?
I'm getting hold of the schematics. Haven't popped it open yet. Thanks for any clues.
