Connect the red test lead to the positive terminal
(anode) of the diode and the black test lead to the
negative terminal (cathode). The cathode of a diode is
indicated with a band.
Read the diode forward bias. If the test lead
connection is reversed, the multimeter will display
"OL".

Testing for Continuity
CAUTION
:
To avoid possible damage to your
multimeter or to the equipment
under test, disconnect the circuit
power and discharge all high-
voltage capacitors before testing
for continuity.
Rotate the rotary switch to
. Press
twice
to enter continuity testing mode,
will be
displayed.
Connect the black test lead to the
terminal and
the red test lead to the
terminal.
Probe the test points to measure the resistance in the
circuit. If the reading is below 30
Ω
, the multimeter
will beep continuously.
