○
Effective value (RMS)
Most alternating currents and voltages are expressed in effective values, which are also
referred to as RMS (Root-Mean-Square) values. The effective value is the square root of
the average of square of alternating current or voltage values. Many clamp meters using
a conventional rectifying circuit have "RMS" scales for AC measurement. The scales are,
however, actually calibrated in terms of the effective value of a sine wave though the clamp
meter is responding to the average value. The calibration is done with a conversion factor of
1
.
111
for sine wave, which is found by dividing the effective value by the average value.
These instruments are therefore in error if the input voltage or current has some other shape
than sine wave.
○
CF (Crest Factor) is found by dividing the peak value by the effective value.
