[GreenKeys] Milliamp meter shunting...

[Kenneth Gartland]

Hi guys...

I have a couple of old Simpson ma meters rated
at 100 ma...

I went to use them to test a known 40ma cct.
the other day, and both pegged at over the scale limit...

Do these older meters require some type of "Shunt"
across the terminals to get an accurate reading?

I know the newer meters can be directly connected in
series with the circuit load...

I used to know this kind of stuff, but too many brain farts
these days to remember!

Tks for help on this issue!

Cheers!
