Ω Resistance, and

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 to select

Continuity function, which is convenient for checking wiring connections and operation

of switches. A continuous beep tone indicates a complete wire.

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

Discharge capacitors before making any measurement. Large value capacitors should

be discharged through an appropriate resistance load.
