Ncv Mode - Beha-Amprobe AT-7000-EUR Mode D'emploi

3. MAIN APPLICATIONS - BREAKERS (DE-ENERGIZED)
Usage tip: For best result try to scan at the output of the breaker/fuse
2
LOCATE
4. Step 2 -
a) Select LOCATE mode by using the directional arrows to
highlight this operating mode and pressing the yellow
"ENTER" button
b) Rescan each breaker/fuse by touching each with the Tip
Sensor for a half second. Active red arrow indicates scanning
process. Make sure the groove on the Tip Sensor is parallel
to the breaker lengthwise. Hint: Hold receiver in the same
position as during scanning step (step 3.5a-c).
c) Rescan all breakers/fuses until solid green arrow and audible
alert (continuous beep) indicates that the correct breaker/
fuse 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.

3.6 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.
ATTENTION: The voltage indication in NCV mode is not sufficient to assure safety. Always
verify the voltage presence/absence with approved voltage 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 Line wire versus Neutral wire, increase or decrease sensitivity
by pressing + or – on the keypad.
5. Press ENTER when complete to return to Home screen.
