Note: Normal forward voltage drop (forward biased) for a good silicon diode is between 0.400V to

0.900V. A reading higher than that indicates a leaky diode (defective). A zero reading indicates a

shorted diode (defective). An OL indicates an open diode (defective). Reverse the test leads

connections (reverse biased) across the diode. The digital display shows OL if the diode is good. Any
