4.10 Computing the Crest Factor
Explanation
4-24
Crest factor computation
The crest factor is determined by peak value/rms value. The WT210/WT230 can
compute the crest factors for voltage and current and show them on display C. " " is
displayed at the front of the value when the crest factor is being displayed.
Computing equation for the crest factor and display
: Displays the result of (Peak of V1)/(rms of V1)
: Displays the result of (Peak of V2)/(rms of V2) (for 760503 only)
: Displays the result of (Peak of V3)/(rms of V3) (for 760502 and 760503)
: Displays the result of (Peak of A1)/(rms of A1)
: Displays the result of (Peak of A2)/(rms of A2) (for 760503 only)
: Displays the result of (Peak of A3)/(rms of A3) (for 760502 and 760503)
Note
Definition of crest factor : PEAK value
•
• If the RMS value is less than or equal to 0.5% (less than or equal to 1% if the crest factor is
set to 6) of the rated range, computation overflow ( --oF-) is indicated.
• If the measurement mode is VOLTAGE MEAN or DC, no data ( -----) is indicated.
