Warning
Before connecting the Meter to the return circuit to be tested, cut off the current
of the return circuit.
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, they should not be
in parallel across the circuit.
To measure current, do the following:
1. Insert the red test lead into the mA or A input terminal and the black test lead
into the COM terminal.
2. Set the rotary switch to μA, mA, or A.
3. The Meter defaults to DC current measurement mode. To toggle between DC
and AC current measurement function, press BLUE button.
4. Connect the test lead in series to the return circuit to be tested. The measured
value is shown on the display.
Display effective value of sine wave (mean value response).
