RE:I have a 200ma Fluke or something like that.

Posted by DAK on June 18, 2017 at 16:55:51:
I have a pair of Japanese ones, they are mini meters, also 200 ma. Since the cathode current should be less than that. It should be ok to just wire it inline or series?
About the fuse If i size it at the same current as the meter it should be what you would want to do?
Thanx for the tips.
