3.3 Non-contact Voltage Mode (NCV) and Passive Tracing

The NCV (Non-Contact Voltage) mode is used to verify if the wire is Energized and to
perform tracing without the use of the Transmitter. The Receiver will detect and trace an
Energized cable if the voltage is between 90 V and 600 V AC and between 40 and 400 Hz.
No current flow is necessary.
Note: For safety, always verify that wires are De-energized with an additional tester before
working with them.
NCV mode operation
1. Press ON/OFF push button to turn on the Receiver.
2. Continue pressing MODE button until the Non-Contact Voltage function is selected.
Passive tracing
Scan the target area with the Tip Sensor to find the highest signal level. While tracing,
periodically adjust the sensitivity to keep the signal strength near 50. Increase or decrease
sensitivity by pressing + or - on the keypad.
Verifying if wire is Energized
Hold the Receiver with the Tip Sensor against the wire. For precise pinpointing of hot wire
versus neutral wire, increase or decrease sensitivity by pressing + or - on the keypad.
