COM
Measurement Procedure:
1. Disconnect power to circuit to be measured.
2. Plug black test lead into the
COM
input jack.
3. Plug red test lead into the
input jack.
4. Set the rotary switch to the
function.
5. Press the orange push button to activate the continuity
buzzer.
6. Connect test leads to circuit to be measured.
7. Listen for the buzzer to confirm continuity.
f. Measuring Diodes
CAUTION
Do not attempt to make diode measurements with circuit
energized. The only way to accurately test a diode is to
remove it completely from the circuit before attempting to
measure it.

Measurement Procedure:
1. Disconnect power to circuit to be measured.
2. Plug black test lead into the
COM
input jack.
3. Plug red test lead into
input jack.
4. Set the rotary switch to the
function.
5. Connect the black test lead to the banded end of the diode
and the red test lead to the non-banded end of the diode.
6. Reading on the display should be between 0.5 and 0.8
volts.
7. Reading test lead connections in 5 above.
8. Reading on the display should be OFL(Overflow).
NOTE: If diode reads 0 in both directions, diode is
shorted. If diode reads OFL in both directions, diode
is open.
