5. Configuración

5.1 Instalación de la batería

The NF-918S requires 1 Lithium Metal battery (included). Ensure the battery is correctly installed according to the polarity markings inside the battery compartment. Charge the device fully before first use.

5.2 Encendido / Apagado

To power on the main unit, press and hold the power button. To power off, press and hold the power button again. The receiver is typically activated by selecting a function using its rotary switch.

6. Instrucciones de funcionamiento

6.1 Cable Scan (Digital/Analog/PoE Mode)

This function helps locate target cables among bundles. Connect the network cable to the RJ45 port on the main unit. Select the desired scan mode (Digital, Analog, or PoE) on the main unit. Use the receiver to trace the cable. The receiver will emit an audible tone, which intensifies as it approaches the target cable.

6.2 Prueba de continuidad del cable

To check for open circuits, short circuits, cross-overs, or other wiring faults in network cables:

1. Connect one end of the network cable to the 'CONT' port on the main unit.
2. Connect the other end of the cable to the 'RECEIVE' port on the receiver.
3. Select the continuity test mode on the main unit. The display will show the wiring status (e.g., open, short, cross). A green LED (G LED) indicates an STP cable.

6.3 Medidor de potencia óptica (OPM)

To measure optical power in fiber optic cables:

1. Connect the fiber optic cable to the OPM port on the main unit.
2. Select the OPM function on the main unit.
3. Use the 'WAVE' button to cycle through the available wavelengths (850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm) to match your fiber.
4. Use the 'UNIT' button to switch between dBm, dB, mW, uW, nW.
5. The 'REF' button allows setting a reference power level for relative measurements.

6.4 Localizador visual de fallas (VFL)

To visually identify faults in fiber optic cables:

1. Conecte el cable de fibra óptica al puerto VFL en la unidad principal.
2. Activate the VFL function. A strong red laser light will be emitted into the fiber.
3. Observe the fiber along its path. Breaks, bends, or poor connections will cause the red light to escape or scatter, making the fault visible.

Figura 6.4: Visual Fault Locator. This image shows the NF-918S main unit with its Visual Fault Locator (VFL) function active, emitting a strong red light into a fiber optic cable to help identify breaks or bends.

6.5 Prueba PoE

To test Power over Ethernet (PoE) functionality:

1. Connect the network cable from the PoE source (e.g., PoE switch) to the main unit's RJ45 port.
2. Select the PoE test mode. The device will automatically identify the power supply type (middle span/end span) and whether the equipment is standard or non-standard PoE.

6.6 Medición de la longitud del cable

To measure the length of various cables:

1. Connect the cable to be measured to the appropriate port on the main unit (e.g., RJ45 for network cables).
2. Select the length measurement function. The device will display the cable length up to 200m. This function supports network cables, telephone lines, and BNC cables.

6.7 vol. sin contactotagDetección de e (NCV)

The receiver unit includes an NCV function for detecting live AC voltage without direct contact. Rotate the receiver's dial to the NCV position. Bring the NCV sensor close to an electrical source (e.g., power outlet, live wire). The receiver will indicate the presence of voltagy mediante alertas visuales y/o audibles.
