PROVA 21 - Specifications: Distortion, Peak Value, Crest Factor; Total Harmonic Distortion (THD-F) Specifications; Peak Value and Crest Factor Specifications

29
Total Harmonic Distortion (THD-F with respect to the first (fundamental)
harmonics, min. value in the range from 45 to 65Hz is greater than AC 80V, greater
than 1A for A range, and greater than 100mA for mA range. Calculation is done over
1 to 50
th
Harmonics. If the voltage or current is 0 in the range from 45 to 65Hz, all the
percentage (%) display is 0)
