DC Current Measurement

(Figure 3)
Never attempt an in-circuit current
measurement where the voltage between
terminals and ground is greater than 60V.
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.
The current measurement has 3 measurement
positions on the rotary switch: 200µA, 200mA and
10A.
To measure current, do the following:
1. Turn off power to the circuit. Discharge all high-
voltage capacitors.

Warning
2. Insert the red test lead into the VΩmA or 10 A
terminal and the black test lead into the COM
terminal.
3. Set the rotary switch to an appropriate
measurement position in A
4. Break the current path to be
tested. Connect the red test
lead to the more positive side
of the break and the black test
lead to the more negative side
of the break.
5. Turn on
power to the
circuit.
