CAUTION
Using Resistance, Continuity, Diode or Capacitance function in a live circuit will produce
false results and may damage the instrument. In many cases the suspected component
must be disconnected from the circuit to obtain an accurate measurement reading.

function. 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).
