There are three basic ways: 1. Bias them into cutoff and drive them into conduction. 2. Bias them normally and drive them into saturation. 3. A combination of the above. Or are you looking for more t

I have a Simpson 923A panel meter, 1 amp full scale. It is reading low by about 6%. When it has 800 ma through it, it indicates about 750 ma. I'll be using it in my 8877 amp at 800 ma and I'd like it
