DC Current Measurement
WARNING
Never attempt an in-circuit current measurement
where the voltage between the terminals and ground is
greater than 60V. If the fuse burns out during
measurement, this may cause harm to the user and/or
damage to the device. Use proper terminals, functions,
and range for measurement.
When the testing leads are connected to the current
terminals, do not parallel them across any circuit.
Figure 3
DC Current Ranges: 2000μA, 20mA, 200mA, 10A
1. Turn off the power to the circuit and discharge all
highvoltage capacitors.
2. Plug the red test lead into the VΩmA or 10A terminal,
then plug the black test lead into the COM terminal.
3. Set the rotary switch to the appropriate
measurement in A range.
4. Break the current path to be tested.
5. Connect the red test lead to the most positive side of
the break and the black test lead to the most
negative side of the break.
6. Turn on the circuit power.
