Measurement Procedure:
1. Disconnect power to circuit to be measured.
2. Plug the black test lead into COM input jack.
3. Plug red test lead into the V/Ωinput jack.
4. Set the rotary switch to the
5. Connect the black test lead to the banded end of
6. Reading on the display should be between 0.5 and
7. Reverse test lead connections in 5 above.
8. Reading on the display should be OFL (Overload).
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.

NOTE: If diode reads 0 in both directions, diode is
shorted. If diode reads OFL in both directions, diode
is open.
