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.
