Function/range switch to
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. 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.
