Press  the

button  momentarily  totoggle the functions. Last selection will  be

saved as power up default for repeat measurement convenience.

In

function, the 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 i ndicates 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 orshorted (defective).

Discharge capacitors before making any measurement. Large value capacitors should
be discharged through an appropriate resistance load.
