5.2 DC Current Measurement
1. Connect the red test lead to the V
Ω
mA input terminal
and the black test lead to the COM input terminal to
measure current up to 200mA. To measure current
between 200mA and 10A, connect the red test lead
to the 10A input terminal. The maximum
measurement time for 10A is 15 seconds.
2. Set the rotary switch to desired DCA range position.
NOTE: If the current amplitude is unknown, select the
highest measurement range, and work down when
necessary.
3. Turn off all power from the circuit under test, and
discharge all capacitors before opening the circuit
to connect the multimeter in series with the circuit.
4. Connect the test leads and turn on the power.
Make the display reading. The polarity to DC current
is automatically displayed.
5.3 Resistance Measurement
1. Connect the red test lead to the V
Ω
mA input terminal
and the black test lead to the COM input terminal.
2. Set the rotary switch to desired resistance (
Ω
) range
position.
