3. MAIN APPLICATIONS - BREAKERS (Energized)

Step 2 -
LOCATE
1. Select LOCATE mode by using the directional
arrows and pressing the yellow ENTER button
(Figure 3.3d).
2. Rescan each breaker/fuse by touching each
with the Tip Sensor for a second. Active red
arrow indicates scanning process. Make sure
the groove on the Tip Sensor is parallel to the
breaker/fuse lengthwise (Figure 3.3e).
Usage Tip: Hold receiver in the same position as
during scanning step
3. Rescan all breakers/fuses until solid green arrow
and audible alert indicates that the correct breaker/
fuse was found (Figure 3.3f).
4. Press ENTER when complete to return to the home screen.
Usage Tip: The accuracy of breaker/fuse identification results can be verified by switching the
Receiver to Energized or 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/fuses.

3.4 NCV Mode
The NCV (Non-Contact Voltage) mode is used to verify that a wire is Energized. This method
does not require 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 Hz and 400 Hz. No current
flow is necessary.
Note: For safety, before working with wires, always verify that they are De-energized with
an additional voltage tester.
�
The voltage indication in NCV mode is not sufficient to assure safety. This function is
not suitable to test for absence of voltage. This always requires a two-pole voltage test.
NCV mode operation
1. Press power button to turn on the Receiver; home screen may take up to 30 seconds to load.
2. Press NCV button to select the Non-Contact Voltage mode.
3. Hold the Receiver with the Tip Sensor against the wire.
4. For precise pinpointing of line/phase wire versus neutral wire, increase or decrease
sensitivity by pressing + or – on the keypad.
5. Press ENTER when complete to return to the home screen.
