MS8218 True RMS Multimeter
Operation Methods
DC mA/AC mA /DC mA + AC mA Measurements
The measurement is seen in the Figure 3-9. The measurement range of current is of AC or DC 1
μ
A
～
500mA and the
measurement methods are as follows:
1.
Turn on the power switch and set the rotary switch to the position
mA
.
2.
Insert the red testing line into the
mA/
μ
μ
μ
μ
A
input end and the black testing line into the COM input end.
3.
Press the
SELECT
key to select the
DC mA
,
AC mA
or the
DC mA + AC mA
measurement modes.
4.
Turn off the power of the measured circuit, connect the red and black probes to the measured circuit in a serial way and
then turn on the power of the measured circuit again.
5.
Read the measured value from the display screen. If it displays as positive during DC measurement, it means the current is
flowing into the meter from the red testing line, while it displays as negative, it means the current is flowing into the meter
from the black testing line. If it displays OL, indicating current exceeding range.
6.
When performing
DC mA or AC mA
measurement, it is possible to select range manually by pressing the RANGE key.
Under the
DC mA + AC mA
measurement mode the automatic range is held and it is null to press the
RANGE
key.
Notes: Under the
DC mA + AC mA
measurement mode, it is relatively slow to refresh the measured data as it needs time to
switch
AC
and
DC
measurements and to calculate RMS.
