WAVEFORMCOMPARISON
Ta b l e3. Illustrates the relationship between AC and DC components for common
waveforms, and compares readings for TRUE RMS meters and average-responding
meters. For example, consider the first waveform, a 1414V (zero-to-peak) sine wave.
Both this Clamp-on meter and RMS-calibrated average-responding meters display
the correct RMS reading of100.0V (the DC component equals 0). However, consider
the 200V (peak-to-peak) square wave, both types of meter correctly measure the DC
component (oV). The clamp meter correctly measures the 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
instruments and true RMS instrument measurements.
