Re: HP 54512B (pair) repair

Harvey - correct me if I'm wrong, but I think the issue is supplying the 3V while working on the battery (soldering with a grounded iron) from an external power supply so the memory would be preserved.? What I'd probably do is run the soldering?station off of an isolated power supply (mine is a BK 1655) with an interrupted ground. I'm not entirely sure on ESD protection, but if I'd do this while supplying the 3V off of an external power supply, that'd probably do OK handling that part.? Radu.?
You could, of course, simply unplug the meter you're working on, so it's
isolated?
Rubber mat if needed.
