That is an oddball meter KW uses. What meter did Doug use?

Tom, I have no idea what meter Doug has there. I have to assume it is not a 500ua meter. If he measures the pot and lets us know what the resistance is that worked we can figure it. My guess is he needed less than the 366 ohms we calculated. Tom. obviously when you clone a meter you are looking for a meter that looks like the original so that it fits and can not be identified as a clone. The originals are not available. So in that case you get the meter that fits the bill and work around it.

He said it read real close on HV. Assuming he did not change resistors in the multiplier resistors, it has to be 500 uA.

If he changed multiplier resistors all bets are off, but since he never said anything about replacing multiplier resistors I assume it was 500 uA.
