NON-CONTACT AC VOLTAGE DETECTOR MODE
o The detector tip cannot be fully inserted into the electrical outlet
o The outlet is a Tamper Resistant (TR) design
o The user is not holding the voltage tester
o The user's hand is insulated from the voltage tester with a glove
o The wire is partially buried or in a grounded metal conduit
o The magnetic field being created by the voltage source is being blocked
or interfered with
o The frequency of the voltage being detected is not a perfect sine wave
and distorted
o The tester is outside of the operating specifications (see Specifications
section below)
o The LED(s) may not be visible in direct sunlight or bright light conditions
The detector may detect at different voltage thresholds under different
conditions or may not detect voltage at all unless the following conditions
o The user is holding the body of the voltage tester with a bare hand
o The user is standing on or connected to earth ground
o The air humidity is nominal (50% relative humidity – non-condensing)
o The voltage tester is held stationary
Operation: Non-Contact (AC) Voltage (NCV) Detector
MODE
1. Press and hold the POWER button to turn the voltage tester on. The
POWER LED will illuminate red. The voltage tester will automatically enter
2. Briefly press the MODE button to switch to the NCV mode. The blue
the voltage tester make some faint clicking sounds. This is normal.
3. Hold the NCV detector tip close to the AC voltage source.
