[ 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
