Selecting ranges
For DC voltage, set the meter to the
VDC parameter instead of VAC as
shown above.
For all ranges and functions choose
a range just above the value you
expect. If display reads "OL" (over-
load), select a higher range. If display
shows less than three numbers, select
a lower range for better resolution.
CE
This instrument complies with the
requirements of the following
European Community Directives:
89/336/EEC (Electromagnetic
Compatibility) and 73/23/EEC (Low
Voltage) as amended by 93/68/EEC
(CE Marking).
Capacitance
True RMS
Digital multimeters use two different
types of AC sensing. The most com-
mon is average sensing, normalized to
a true RMS value of a sine wave. The
other is true RMS sensing. The actual
true RMS value is sensed for a wave
form within the limits of the crest factor.
Either sensing method will give the
same results on a clean sine wave but
they may differ on a non-sinusoidal
waveform.
