The diode test measures the voltage drop across a diode junction.
test leads as shown in figure 5.
Apply probe tip of red lead to the anode and of black lead to the cathode of the
diode.
The meter's display indicates the forward voltage drop (approx. 0.6V for
silicon diode or 0.4V for germanium diode). An open diode is indicated by "I OL".
Reverse test lead connections to the diode to perform a reverse bias test. "I OL"
indicates a good diode. Notes: "I OL" for both reverse and forward bias tests
indicates an open diode. A low voltage reading for both bias tests indicates a
shorted diode. If the diode is shunted by a resistor of 1000 ohms or less, it must
be removed from the circuit before taking the measurement. Bipolar transistor
