[5] Measuring procedures

5-1 Pre-operational Check

1. Do not use the instrument if the meter or test leads look 

damaged.

2. Make sure the test leads and the fuse are not broken.

WARNING

Make sure the low battery indicator is off after power-on. Replace 
the battery with new one if the indicator is on.

CAUTION

Perform pre-oparational check for safety.

(Inspection using continuity check)

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 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.
