5.
Press the
Range/Diode/Continuity
button
so that
shows on the LCD.
6.
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.
7.
Reading on the display should be between
0.3 and 0.8 volts.
8.
Reverse test lead connections in 6 above.
9.
Reading on the display should be OFL
(Overload).
NOTE: If diode reads 0 in both directions, diode is short-
ed. If diode reads OFL in both directions, diode is open.

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.
