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 of harmonics. This instrument employs the True-RMS (Root-Mean-Square) detection.

Crest Factor

Crest Factor is the ratio of the Crest (instantaneous peak) value divided by the True RMS value. Most common waveforms such as 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 following table. Please note that measurement should be made under the crest factor below 3.

	Input Waveform	0 to PEAK Vp	RocI Mean Square Value Vrms	Average Value Vavg	Crest Factor Vp/Vrms	Form Factor Vrms/Vavg
Sinusoidal wave	|c:c Vp & 2 \ 0 & p	Vp	2 =0.707Vp	2Vp =0.637Vp	2 =1.414	22 =1.111

How to calculate an accuracy

Example) DC voltage measurement (DC mV)

True value: 100.0 [mV]

Range accuracy: ±(0.06 %rdg+2 dgt) in the 600.0 mV range

Measuring error: ±(100.0 [mV]×0.06 % rdg +2 dgt)

$$ \doteq \pm 0. 3 [ \mathrm{mV} ] $$

Calculation: 100.0 [mV] ±0.3 [mV]

Reading: 099.7 [mV] to 100.3 [mV]

* 2 dgt in the 600.0 mV range corresponds to 0.2 mV.
