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 may be hurt.
Use the proper terminals, function, and range for each measurement.
When the testing leads are connected to the current terminals, do not connect
them in parallel to any circuit.
To measure current, do the following:
1.
Insert the red test lead into the
μmA
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 the
DC and AC current measurement function, press
the
BLUE
button.
4.
Connect the test lead in series to the return line of the circuit to be tested. The
measured value is shown on the display.
