Total Harmonic Distortion
(THD-F with respect to the fundamental frequency, min. value at 50 or 60 Hz is
voltage > AC 80V and current is: model AD6801> 10% of the range;
model AD6802> 20A; model 3007> 30A. Calculation is done
over 1 to 50
th
Harmonics. If the voltage or current is 0 at 50 or 60 Hz, all the
percentage (%) display is 0).
