Set the
Function/range switch to
position.
❸
Apply probe tip of red lead to the anode
and of black lead to the cathode of the diode.
❹
The meter’s display indicates the
forward voltage drop (approximately 0.6V for silicon diode or 0.4V for germanium
diode). Meter will display overload condition for an open diode.
➎
Reverse test lead
connections to the diode to perform a reverse bias test. Overload indicates a good diode.
Notes: Overload condition for both reverse and forward bias tests indicate an open
diode. A low voltage reading for both bias tests indicates a shorted diode. Bipolar
transistor junctions may be tested in the same manner described above.
