Here is the deal with the new meter that dawned on me the other day.
It is special and for a reason.
It measures micro amps.
You have to measuer micro amps to test flame detectors in furnaces, not all meters do this.
I have never had a meter that measured micro amps before.
One micro amp is one millionth of an amp,the micro symbol looks like this µ.
A milliamp is one thousandth of an amp.
