Yes, Rob. I late also thought about it that way while answering
Hello!
I would like to measure insulation resistance of some defective load cells.
The measurement should be done with no more than 50V and the full scale
reading should be >=5Gohm. Accuracy of +-10% is enough (in fact it could
suffice just to check if it's >=5Gohm or not).
I have not been able
50V across 5GOhm is 10nA. Put a standard multimeter's 10MOhm input in
series and
you have 10mV per nA reading. Anything below 100mV is pass.
My 2 eurocents.

Also, quite a few of the Fluke portable and handheld DMMs from the
