    Measurement Tutorial True RMS AC Measurements True RMS responding multimeters, like the Agilent 34410A/34411A, measure the "heating" potential of an applied voltage. Power dissipated in a resistor is proportional to the square of an applied voltage, independent of the waveshape of the signal. This multimeter accurately measures true RMS voltage or current, as long as the wave shape contains negligible energy above the meter’s effective bandwidth.
