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.
