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

other readings indicate the diode is resistive or shorted (defective).

Temperature Function

Press SELECT button momentarily to toggle between °C and °F readings, and

the new setting will be saved automatically in the non-volatile memory as

power up default.
