Paul_KD7HB:
You failed to tell us the frequency of your AC. Is your meter AC calibration correct for that frequency?Paul
Well, the frequency I was testing these with is 40Hz, but that will vary. It may not always be 40Hz being tested. My multimeter reads the same voltage as my AMM-1 Audio Multimeter, which is designed to accurately measure varying audio signals from amplifiers and read Vrms, Arms, frequency, live impedance, power factor, Volt-Amps, and actual Wattage.
I am basically trying to duplicate the results I get on the AMM-1 on my arduino project.
