True RMS: The term stands for “Root-Mean-Square,”
which represents the method of calculation of the
voltage or current value. Average responding
multimeters are calibrated to read correctly only on
sine waves and they will read inaccurately on non-
sine wave or distorted signals. True rms meters read
accurately on either type of signal.
