Table 3. illustrates the relationship between AC and DC components for common

waveforms, and compares readings for TRUE RMS meters and average-respond-

ing meters. For example, consider the first waveform, a 141.4AV (zero-to-peak)

sine wave. Both this Clamp-on meter and RMS-calibrated average-responding

meters display the correct RMS reading of 100.0V(the DC component equals 0).

AC component (100.0V). The average-responding meter measures 111.1V, which

amounts to an 11 %error.

The conversion factors in Table 3 show the differences between average sensing

instrument measurements and true RMS instrument

However, consider the 200V(peak-to-peak) square wave, both types of meter cor-

rectly measure the DC component (0V). The clamp meter correctly measures the
