1. Connect the black test lead to the COM terminal and the
red test lead to the mA terminal for a maximum of 200 mA.
For a maximum of 10 A, move the red test lead to the 10 A
terminal.
2. Turn circuit power off.
3. Break the circuit path to be tested. Connect the black
test lead to the more negative side of the break; connect
the red test lead to the more positive side of the break.
(Reversing leads will give a negative reading, but will not
damage the meter.)
4. Turn on the power of the measured circuit and read the
display. Be sure to note the measurement units at the
right side of the display (mA or A). When only the figure
“1” is displayed, it indicates an overrange situation and the
higher range has to be selected.
5. Turn off the power of the measured circuit and discharge
any high voltage capacitors. Remove the test leads and
reconnect the test circuit.
