Diode test function
Inputs are made through the test leads terminals. Slide-switch on 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. Slide-switch on defaults at
Ω
. Press
SELECT
button momentarily 3 times to select
Capacitance function. Relative zero
mode can be used to zero out the parasitic capacitance of the leads and the internal
protection circuitry of the meter when measuring low capacitance in the order of Pico
Farad (pF).
CAUTION
Discharge capacitors before making any measurement. Large value capacitors should
be discharged through an appropriate resistance load
