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. Please note that measurement
should be made under the crest factor below 3.
