[ 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) ]
CF (Crest Factor) is found by dividing the peak value by the
effective value.
Examples: Sine wave: CF=1.414
Square wave with a 1: 9 duty ratio: CF=3
