АМM-1130
DC /AC A Measurement
The measurement is seen in Figure 3-10, the measurement range of current is of AC or DC 1mA～10A 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 A input end and the black testing line into the COM input end.
3.
Press the FUNC. key to select the DC A or 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 null to press the RANGE key.
