4-15 Terms
Analog bar graph
The analog bar graph provides a visual indication of
measurement like a traditional analog meter needle.
True RMS
True RMS is a term which identifies a DMM that responds
accurately to the effective RMS value regardless of the
waveforms such as square, sawtooth, triangle, pulse trains,
spikes, as well as distorted waveforms with the presence ofharmonics. This instrument employs the True-RMS (Root-MeanSquare) detection.
Crest Factor
Crest Factor is the ratio of the Crest (instantaneous peak) value
divided by the True RMS value. Most common waveforms suchas sinusoidal wave and chopping wave have a relatively low
crest factor. A low duty cycle wave form like pulse string has
a high crest factor. For voltages and crest factors for typical
waveforms, see the table below.
