MS8218 True RMS Multimeter
Operation Methods
DCV/DCV + ACV Measurement
The measurement is shown in Figure 3-2,the range of voltage is of AC or DC 0.5V
~
1000V and the methods are as follows:
1.
Turn on the power switch and set the rotary-table switch to the position
V
.
2.
Insert the red testing line into the
V
Ω
Ω
Ω
Ω
Hz
end and the black testing line into the
COM
end.
3.
Press
SELECT
key to select
DCV
or
DCV + AC
V measurement mode.
4.
When performing DCV measurement, connect the red probe to the positive polarity of the measured voltage and the
black probe to the negative polarity of the measured voltage. While performing DCV + ACV measurement, it will be
done by connecting the red probe and the black probe into the two ends of the measured voltage.
5.
Read the measured value from the display screen. If OL displaying on the meter, it indicates the measured voltage
exceeding the range of the meter and it is necessary to remove the both red and black probes from the measured circuit
immediately.
6.
When performing DCV measurement, by pressing the
RANGE
key it is possible to select range manually. The
indicator of range indicates the range value. If OL displaying during manual range measurement, it is necessary to
select a larger range. If OL displaying under the maximum range, it indicates the voltage exceeding 1000V and it is
necessary to remove the both red and black probes from the measured circuit immediately.When performing DCV +
ACV measurement automatic range will be held and it is null to press the
RANGE
key.
Notes: in case of probe hanging in the air, the voltage inducted by the testing line may cause unstable readings on the
display screen, but that will not affect the accuracy of measurement. When performing DCV + ACV measurement it will be
relatively slow to refresh the measured data as it needs time to switch AC and DC measurements and to calculate RMS.
