Non-Contact Voltage-Detector (NCV)
The area at the top of the clamp jaws is used for sensing AC voltage.
When the electrical field is > 100V and the distance is < 10mm from the tip of the meter's clamp
jaw, the beeper will sound and the red LED lamp will light.
The NCV lamp flashes at the same rate as the beeper. The higher the field strength, the faster
the beep rate and lamp flashing.
When the sensed field is at highest levels, the meter's NCV lamp and beeper rate will become
one continuous light and tone.
If the meter does not react as described above to an AC voltage, there is still the possibility that
a voltage is present. Please use caution.
1.
Move the function switch to the NCV position.
2.
In this mode, the meter will display 'OL' and 'NCV'.
3.
Place the meter near a source of electrical energy. The tip of the clamp offers the highest
sensitivity.
4.
Note the beeping and the NCV lamp activation when an AC Voltage is sensed.
