Diode test function
Inputs are made through the test lead terminals. Move the slide-switch to the “Ω”
position. The unit defaults at Ω. Press SELECT button momentarily 2 times to select
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).
Capacitance function
Inputs are made through the test leads terminals. Move the slide-switch to the “Ω”
position. The unit defaults at Ω. Press SELECT button momentarily 3 times to select
Capacitance function.
CAUTION
Measuring Resistance, Continuity, Diode or Capacitance function on 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.
