*The crest factor is the ratio of the peak value to the RMS value; it is

represented by the Greek letter ξ.

AC Measurement

AC measurements are usually displayed as RMS (root mean squared)

values. Two methods of AC measurement are

average-responding RMS

calibrated

and

true RMS-reading.

The average-responding RMS calibrated method takes the average value of

the input signal, multiplies it by 1.11, and displays the result. This method

is accurate if the input signal is a pure sine wave. The Greenlee DM-310 is

an average-responding meter.

The true RMS-reading method uses internal circuitry to read the true RMS

value. This method is accurate, within the specified crest factor limitations,

whether the input signal is a pure sine wave, a square wave, sawtooth

wave, half wave or signal with harmonics. The ability to read true RMS

provides much more measurement versatility. The Greenlee DM-300,

DM-330, and DM-350 are true RMS meters.

The Waveforms and Crest Factors table shows some typical AC signals and

their RMS values.
