Many industrial DVM's will work for this.=C2=A0 The Fluke 70-series (I'm d=

Thanks,That 30 sec. I mentioned=C2=A0was incorrect. It stays on for about 3=
0 sec and then blinks. If anyone wants the TSB, it is attached. With this T=
SB it's comparing one reference to another known reference.=C2=A0
I did some experiments yesterday. Tying to measure 10 volts is not as strai=
ghtforward with a digital meter. I think I need to create a voltage divider=
network and measure that way.From another forum post I found from Randall =
Yong and some other guy, you really don't=C2=A0want to drive=C2=A0more than=
8 or 9 volts directly to a gauge. The needle goes off the top of the scale=

I have some time with shelter in place and am more curious to get my gauges=
