Diode functions
Inputs are made through the test lead terminals COM/+. Defaults at Ω Ω Ω Ω Resistance.
Press SELECT button momentarily to select the subject functions in sequence.
Note
When using Diode test 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).
CAUTION
Using Resistance, Continuity or Diode function in a live circuit will produce false results
and may damage the meter. In many cases, the suspected component(s) must be
disconnected from the circuit to obtain an accurate measurement reading.
