DC/AC mA Measurements
The measurement is seen in the Figure 3-9
The measurement range of current is of AC or DC 1 μA
～
220mA and the
measurement methods are as follows:
1.
Turn on the power switch and set the rotary switch to the position .
2.
Insert the red testing line into the
mA/μA
input end and the black testing line into the COM input end.
3.
Press the
FUNC.
key to select the
DC mA
or
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.
Notes: In this mode the Meter may display a initial reading between 1 and 5 counts when no signal input, but that will not affect the
accuracy of measurement. Using REL to offset this reading may produce a much larger constant error in later measurements.
