Warning
Before connecting the Meter in serial to the tested in-circuit, disconnect in-circuit power.
If the fuse burns out during measurement, the Meter may be damaged or the operator himself
may be hurt.
Use proper terminals, function, and range for the measurement. When the testing leads are
connected to the current terminals, do not parallel them across any circuit otherwise it will
burn the fuse or damage to the Meter.
To measure AC/DC current, connect the Meter as follows:
1. nsert the red test lead into the “ȝA” “mA” or “A” terminal and the black test lead into
the COM terminal.
2. Set the rotary switch to an appropriate measurement position in “ȝA” “mA” or “A” .
Press blue button to switch between AC and DC measurement mode.
3. C current measurement displays true rms value. Press Hz button to obtain the frequency value
(refer to accuracy specifications for maximum ranges).
4. onnect the test leads with the object being measured. The measured value shows on the
display.
Note
Ɣ
If the value of the current to be measured is unknown, use the maximum measurement position
10A terminal, and reduce the range step by step until a satisfactory reading is obtained.
Ɣ When current measurement has been completed, disconnect the connection between the testing
leads and the circuit under test.
Ɣ When measuring 5A~10A: maximum continuous measurement should be 10 seconds
