HP 410C Meter pegs upscale Check A1R10?
« on: November 01, 2024, 08:19:07 pm »
It was working fine on resistance measurement, but then, after about 15 minutes, the meter pegs upscale, and the manual shows the possible cause as  A1R10 250 ohms. I think it's an intermittent cold solder joint or a failing 250 ohm resistor. At 84, my eyes aren't that good, so I need some help. If someone has an open unit, a picture or a description of its location would be nice.
Thanks
Hank
