MEASUREMENT METHOD
Vrms, Arms 10/12
1
contiguous non overlapping intervals using 500/416
1
samples per cycle
in accordance with IEC 61000-4-30.
Vpeak, Apeak Absolute highest sample value within 10/12
1
cycle interval with 40 µs sample
resolution.
V Crest Factor Measures ratio between the Vpeak and Vrms.
A Crest Factor Measures ratio between the Apeak and Arms.
Hz Measured every 10 sec in accordance with IEC61000-4-30.
Vrms½, Arms½ value is measured over 1 cycle, commencing at a fundamental zero crossing,
and refreshed each half-cycle. This technique is independent for each channel
in accordance with IEC 61000-4-30.
