I measure meters with my digital ohm meter at least a few times a week and have been
since I had high impedance ohm meters. Never blew up a meter yet. Of course
you have to know how to do it.

## Never had a problem so far..with my fluke 87 across meter movements..and they were 0- 1
ma types, if I remember correctly.
I think this was with 87A manually switched to lower scales.
## I used to wire rvs connected diodes across both plate and also
grid meter.
These days I just wire the rvs diodes.. between B- and chassis. In
some cases
2 diodes are used in series... 4 in total.
In some cases, a resistor is wired in series with each rvs connected
diode...that was a
W6WRT trick..which works good.
