1.
Plug the RED test lead into the "mA" or the "DC10A" jack
of the multimeter, as applicable; plug the BLACK test lead
to the "COM" jack.

2.
Set the meter's Function/Range Selector Switch to the
appropriate Amps range position as desired (see Controls
and Indicators, Items 4, 10 and 11).
To measure from 0 to 200mA, set the Selector Switch
to the "DCmA" or "ACmA" position, as applicable.
To measure from 200mA to 10 Amps DC, set the
Selector Switch to the "DC10A" position.
3.
Disconnect the battery, or shut off the power to the circuit
being tested.
NOTE: To measure current on a particular circuit, you must
open up the circuit and connect the test leads in series with
the circuit before a reading can be obtained.
4.
Disconnect one end of the wire or device, from the circuit
where current will be measured.
5.
Place the RED test lead on the disconnected wire and
place the BLACK test lead at the location from which the
wire was disconnected (series connection).
6.
Reconnect the battery, or apply power to the circuit being
tested.
7.
Read the results on the display.
CAUTION: After the test is completed, shut the power off
to the circuit before removing the test leads and before
reconnecting any disconnected wires or devices.
NOTE: If the reading obtained is a negative number, reverse
the test leads.
