TRUERMSMEASUREMENT
The meter measures the TRUERMS value of AC voltages and currents. In physical
terms, the RMS (Root-Mean-Square) value of a waveform is the equivalent DC val-
ue that causes the same amount of heat to be dissipated in a resistor. TRUE RMS
measurement greatly simplifies the analysis of complex AC signals. Since the RMS
value is the DC equivalent of the original waveform, it provides a reliable basis for
comparing dissimilar waveforms.
By contrast, many meters use average-responding AC
converters rather than TRUE RMS converters. The scale
factor in these meters are adjusted so that they display the
RMS value for a harmonic-free sine wave. If a signal is not
sinusoidal, average-responding meters do not display
correct RMS readings.
