THD – PWHD – K factor

All calculations are based on a 10/12 cycle averaging interval  
(50 Hz = 10 cycles / 60 Hz = 12 cy-cles),

according the formula of IEC61000-4-7  
(exactly 2024 sample values will be used for calculation)

The THD calculation of voltage and current can be changed in the settings:  
2 – 40th or 2 – 50th
