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.
