12 ELECTRICIAN’S MULTIMETER
AC/DC CURRENT MEASUREMENT
WARNING
!
• To prevent possible electric shock, fire or personal injury, switch off
the power supply of the circuit before measuring the current, and then
connect the meter with the circuit in series.
• Use the proper terminals, switch position, and range for your
measurement. If the range of the measured current is unknown, select
the maximum range and then accordingly reduce.
• There are fuses built in to the 20A and mA/µA terminals. Never place
the probes in parallel with a circuit or component when the leads are
plugged into these A (Amps) terminals.
Switch the function selector to A position the green indicator should be on.
1. According to the current being measured, connect the common test lead to COM terminal,
then insert the red test lead to mAµA or 20A terminal
2. Connect the test leads with the circuit in series.
NOTE:
•
Readings of AC measurement are true RMS.
•
If the tested current is 6A~10A, the Max measurement time should not exceed 60 seconds,
and the next test should be after 1 minute.
•
If the tested current is >10A, the Max measurement time should not exceed 10 seconds,
and the next test should be after 15 minutes.
•
When measuring AC current, short press (<2S) SEL/REL button to display AC frequency.
