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 (BM111
& BM112 only) 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
ACA Current Clamp-on Function
Inputs are made through the clamp jaws for non-invasive ACA current measurements.
In BM111 & BM112, the single input single display models, use the slide-switch to select the
ACA function.
In BM125 & BM126s, the dual inputs twin displays 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.
CAUTION
Press the jaw trigger and clamp the jaws around only one single conductor of a circuit for load
current measurement. Make sure the jaws are completely closed, or else it will introduce
