Stan, with the dial set to 50 the meter reads just 1 volt (from the bottom row of the scale you cited).
Rob - I don't think I can measure with load since the meter probes have to go in the plug and on the outside to make a circuit. Are you thinking 8.5 volts would be normal in the unloaded state? Trying to figure out why some people's Menards buildings are frying.
Thanks, everyone, I'll see if I can find a digital meter.
