True RMS
Digital Multimeter
User Manual
AC 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.
