Test Leads
OPERATION:
Non-contact voltage (NCV)
With the NCV tab on the tip of the clamp close to an AC voltage, press the NCV but-
ton. The NCV LED will light and the beeper will sound. The closer the NCV tab is to
AC voltage, the louder the beep. To differentiate between hot and neutral in an outlet,
insert the NCV tab into each slot in the outlet. The beeper will be much louder on the
hot side of the outlet than the neutral. The test lead can also be used to differentiate
between the hot and neutral. Plug the red test lead into the V/Ω input jack on the
meter. Press the NCV button and insert the probe tip into each slot of the outlet. The
beeper will only beep on the hot side of the outlet.
