Meter Operation
Non-Contact Voltage Sensing
First, rotate the function key to the NCV position. Place the sensing point marked
with NCV close to an AC outlet (or any AC conductor such as light switches or
power cords) and scan back and forth across the outlet. The meter beeps On/Off
continuously and the Red NCV LED above the display flashes if the sensing antenna
detects live voltage greater than 40V AC (50 -60 Hz). Voltages with frequencies
higher than 60Hz or electrostatic charges may also be detected by the NCV sensing
antenna. To differentiate between hot 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.
NOTE: 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.
