First, rotate the function key to the NCV position. Place the jaw tip marked with
ment.
NCV close to an AC outlet (or any AC conductor such as light switches or power
ut
cords) and scan back and forth across the outlet. Red indicator LED flashes at a
frequency of 3Hz, and the buzzer beeps at a frequency of 3Hz simultaneously if live
voltage is greater than 40VAC (50~60Hz) is detected. To differentiate between hot
ds
and neutral in an outlet, place the NCV tab directly next to each slot in the outlet.
The tone (buzzer) will sound over the slot that is energized and not on the neutral
slot. Either test lead can also be used to differentiate between the hot and neutral.
Plug the red or black test lead into the V input jack on the meter. With the function
switch in the NCV position, insert the probe end of just one probe into the slots on
the outlet. The meter will beep and the Red LED will flash when a hot conductor is
contacted.
NOTES:
ge
While the NCV is a helpful function, it is ALWAYS RECOMMENDED
that the operator verify that any electrical conductor is completely de-
energized and that no voltage is present by measuring for voltage AND
CONFIRMING THAT NO VOLTAGE IS PRESENT and that all applicable
PPE and lock out tag out procedures be followed before attempting any
work on ANY electrical distribution system.
Voltages with frequencies higher than 60Hz or electrostatic charges
may also be detected by the NCV sensing antenna.
