MS8218 True RMS Multimeter
Operation Methods
DC Ampere/AC Ampere/DC AC Ampere Measurement
The measurement is seen in Figure 3-10, the measurement range of current is of AC or DC 0.1mA
～
10A and the
measurement methods are as follows:
1.
Turn on the power switch and set the rotary switch to the position
A
.
2.
Insert the red testing line into the A input end and the black testing line into the
COM
input end.
3.
Press the
SELECT
key to select the
DC A, AC A
or
DC A + AC A
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. During the
DC
measurement, if it displays as positive, 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, it indicates current exceeding range.
6.
When performing
DC A or AC A
measurement, it is possible to select range manually by pressing the Range key. Under
the
DC A + AC A
measurement mode, automatic range is held and it is null to press the
RANGE
key.
Notes: Under the DC A + AC A measurement mode, it is relatively slow to refresh the measured data as it is needs time to
switch AC and DC measurements and to calculate RMS.
