Charging the Device

The NF-8508 comes with a built-in rechargeable lithium battery. Before first use, fully charge both the transmitter and receiver units using the provided USB-C charging cable and a compatible USB power adapter (not included). The battery indicator on the screen will show charging status.

Powering On/Off

Press and hold the power button (U icon) on both the transmitter and receiver units to power them on or off. The screen will illuminate upon power-on.

Operating Instructions

The NF-8508 features a user-friendly interface with a main menu for selecting different functions. Use the directional buttons (Up, Down, Left, Right) and the OK button to navigate and confirm selections.

1. Cable Continuity Test (CONT / QC Test)

This function verifies the correct wiring sequence and continuity of RJ11 and RJ45 cables.

1. Connect one end of the RJ45 or RJ11 cable to the 'RJ45' or 'RJ11' port on the transmitter unit.
2. Connect the other end of the cable to the corresponding port on the receiver unit.
3. Select 'CONT' or 'QC Test' from the main menu on the transmitter.
4. Press 'OK' to start the test. The screen will display the wiring status for each pin. A green checkmark indicates correct continuity, while a red 'X' or missing line indicates a fault.

2. Cable Scanning (SCAN)

Used to trace and locate specific cables within a bundle or wall.

1. Connect the cable to be traced to the 'SCAN' port of the transmitter unit.
2. Select 'SCAN' from the main menu. You can choose between 'Digital Mode' or 'Analog Mode' based on your preference and environment.
3. Use the receiver unit to scan the cables. The receiver will emit an audible tone, which becomes louder as it approaches the target cable.

3. Port Flicker (FLASH)

Helps identify the port on a network switch or router to which a cable is connected by making the port's indicator light flash.

1. Connect the RJ45 cable to the 'RJ45' port on the transmitter unit.
2. Connect the other end of the cable to a port on the network switch.
3. Select 'Flash' from the main menu. The transmitter will send a signal that causes the connected switch port's LED to blink, allowing for easy identification.

4. Length Measurement (LENGTH)

Measures the length of an Ethernet cable.

1. Connect one end of the RJ45 cable to the 'RJ45' port on the transmitter unit. The receiver unit is not needed for this function.
2. Select 'Length' from the main menu.
3. Press 'OK' to initiate the measurement. The screen will display the cable length in meters.

5. PoE Power Test (POE)

Tests Power over Ethernet (PoE) voltage and polarity.

1. Connect the RJ45 cable from the PoE source (e.g., PoE switch) to the 'RJ45' port on the transmitter unit.
2. Select 'POE' from the main menu.
3. The screen will display the PoE voltage, polarity, and standard (e.g., IEEE 802.3af/at).

6. Optical Power Meter (OPM)

Measures the power of optical fiber signals.

1. Connect the optical fiber to the 'OPM' port on the transmitter unit. Ensure the correct adapter (FC/SC/ST) is used.
2. Select 'OPM' from the main menu.
3. The screen will display the optical power in dBm for the selected wavelength. You can cycle through different wavelengths (850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm) and perform calibration if needed.

7. Visual Fault Locator (VFL)

Locates breaks or faults in optical fibers using a visible red laser.

1. Connect the optical fiber to the 'VFL' port on the transmitter unit. Note: An LC converter head may need to be purchased separately for LC connectors.
2. Select 'VFL' from the main menu.
3. A red laser light will be emitted. Observe the fiber for any light leakage, which indicates a fault.

8. Non-Contact Voltage (NCV) Function

Detects the presence of AC voltage without direct contact.

1. On the receiver unit, rotate the dial to the 'NCV' position.
2. Bring the NCV sensor (top part of the receiver) close to the wire or electrical outlet.
3. The NCV light will illuminate and an audible alarm will sound if AC voltage is detected.
