Resistance, Continuity, Capacitance, & Diode test functions
Press the
SELECT
button momentarily to select the subject functions in sequence. Last
selection will be saved as power up default for repeat measurement convenience.
CAUTION
Discharge capacitors before making any measurement. Large value capacitors should
be discharged through an appropriate resistance load.
CAUTION
Using resistance and continuity function in 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 reading
Continuity function is convenient for checking wiring connections and operation of
switches. A continuous beep tone indicates a complete wire.
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).
