4. Step 2 - LOCATE
a) Select LOCATE mode by using the directional arrows to highlight this operating mode
and pressing the yellow "ENTER" button.
b) Scan each breaker again for a half second each by touching it with the Tip Sensor.
Active red arrow indicates scanning process. Make sure the groove on the Tip Sensor is
parallel to the breaker lengthwise.
c) Rescan all breakers until solid green arrow and audible alert (continuous beep)
indicates that the correct breaker was found.
d) Press ENTER when complete to return to Home screen.
Usage Tip: The accuracy of breaker location can be verified by switching the receiver to
De-Energized TIP SENSOR mode, and checking that that the signal level of the breaker
identified by the receiver is the highest among all breakers.
3.4 NCV Mode
The NCV (Non-Contact Voltage) mode is used to verify that the wire is energized. This
method does not require the use of the transmitter. The receiver will detect an energized
cable if the voltage is between 90V and 600V AC and between 40 and 400Hz. No current
flow is necessary.
Note: For safety, before working with wires, always verify that they are de-energized with
an additional tester.
NCV mode operation:
1. Press 'ON/OFF' push button to turn on the receiver and wait for the home screen (boot
up time is around 30 seconds).
2. Press 'NCV' push button to select the Non-Contact Voltage mode.
3. Hold the receiver with the Tip Sensor against the wire.
4. For precise pinpointing of hot wire versus neutral wire, increase or decrease sensitivity
by pressing + or – on the keypad.
5. Press ENTER when complete to return to Home screen.
