NOTE:
The conductors in electrical cord sets are often twisted. For best results, rub
the probe tip along a length of the cord to assure placing the tip in close proximity
to the live conductor.
NOTE:
The detector is designed with high sensitivity. Static electricity or other
sources of energy will randomly trip the sensor. This is normal operation.
If AC voltage is present, the detector cone will produce a steady constant
glow.
Place the probe tip near the hot conductor or next to the hot side of the
electrical outlet.
The cone tip will light up for approximately 2 seconds and then turn off,
ensuring that the LED is working correctly. Continue holding the NCV button.
PRESS and HOLD the NCV button.
