Ω Ω Ω Ω Resistance, and Continuity functions
Inputs are made through the test leads terminals. Slide-switch on 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 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 (not available to Model 110M)
Inputs are made through the test leads terminals. Slide-switch on defaults at Ω. Press
SELECT button momentarily 3 times to select Capacitance function.
Note: (applies to Models 111M & Model 112M only)
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 measurements. Large value capacitors
should be discharged through an appropriate resistance load
ACA function
Inputs are made through the clamp jaws for non-invasive ACA current measurements.
For Single Display Models, set the slide-switch to select the ACA function.
For dual inputs Twin Display Models, press the OFF push button momentarily to power
on and off the separate ACA function display. The HOLD push button can also be used
as the ACA function power on hotkey. This twin display ACA function can be used
simultaneously with the voltage or any other slide-switch functions when making
measurements.
