5. Operating Instructions

The NF-8518 offers a range of testing functions accessible via the Transmitter's menu and the Receiver's dedicated buttons.

5.1 Cable Continuity Testing (CONT)

This function checks for open circuits, short circuits, and cross connections in network cables.

1. Connect one end of the RJ45 cable to the SCAN/CONT port on the Transmitter.
2. Connect the other end of the RJ45 cable to the RJ45 port on the Receiver.
3. On the Transmitter, navigate to the 'CONT' option in the main menu and press OK.
4. The screen will display the continuity status for each wire pair.

5.2 Cable Scanning (SCAN)

Used to locate a specific cable among a bundle of cables.

1. Connect one end of the RJ45 cable to the SCAN/CONT port on the Transmitter.
2. On the Transmitter, navigate to the 'SCAN' option in the main menu and press OK.
3. Turn on the Receiver and press the SCAN button.
4. Move the Receiver's probe along the cables. The Receiver will emit an audible tone and its scan lights will illuminate when the target cable is detected.

5.3 Cable Length Measurement

Measures the length of network cables (RJ45).

1. Ensure the cable is disconnected from all network devices.
2. Connect one end of the RJ45 cable to the SCAN/CONT port on the Transmitter.
3. On the Transmitter, navigate to the 'Length' option in the main menu and press OK.
4. The device will automatically measure and display the cable length.

5.4 PoE Testing

Tests Power over Ethernet (PoE) status and voltage.

1. Connect the RJ45 cable from the PoE source to the SCAN/CONT port on the Transmitter.
2. On the Transmitter, navigate to the 'PoE' option in the main menu and press OK.
3. The device will display information about the PoE standard (IEEE802.3 at/af or Non-Standard), power supply method (End Span/Mid Span/8-pin), and voltage.

5.5 Port Flashing

Helps quickly locate the target cable by making the corresponding port LED on a switch or router flash.

1. Connect the RJ45 cable to the SCAN/CONT port on the Transmitter and the other end to a port on a network device (e.g., switch).
2. On the Transmitter, navigate to the 'Flash' option in the main menu and press OK.
3. Observe the network device; the connected port's LED will flash, allowing for easy identification.

5.6 Crimping Quality Test (QC Test)

Accurately identifies poor crimping by testing the continuity between RJ45 contacts and cable cores.

1. Connect the crimped RJ45 connector to the SCAN/CONT port on the Transmitter.
2. On the Transmitter, navigate to the 'QC Test' option in the main menu and press OK.
3. The device will analyze the crimp quality and display results, helping to ensure network stability.

5.7 Optical Power Meter (OPM)

Measures the power of optical fiber signals across multiple wavelengths.

1. Select the desired wavelength from the OPM menu on the Transmitter.
2. Connect the fiber optic cable to the OPM port on the Transmitter.
3. The device will automatically detect and display the optical power in dBm.

5.8 Visual Fault Locator (VFL)

Emits a visible red laser to detect faults in fiber optic cables.

1. Connect the fiber optic cable to the VFL port on the Transmitter.
2. On the Transmitter, navigate to the 'VFL' option in the main menu and press OK to activate the laser.
3. Observe the fiber optic cable for any visible red light leakage, which indicates breaks, cracks, or bends.

5.9 Non-Contact Voltage (NCV) Detection

The Receiver unit can detect live electrical equipment and wires without direct contact.

1. Turn on the Receiver unit.
2. Press the NCV button to activate the NCV function.
3. Move the anti-jamming probe near the suspected electrical source (wires, outlets). The NCV light will illuminate, and an audible 'di' sound will indicate the presence of voltage.

The Receiver unit features two LED lighting beads to assist in dark working environments.

1. Turn on the Receiver unit.
2. Press the dedicated LED button (or the Power button briefly if it doubles as the LED control) to activate the high-brightness LED light.

6. Maintenance

6.1 General Care

• Keep the device clean and dry. Wipe with a soft, damp cloth if necessary. Do not use abrasive cleaners or solvents.
• Store the device in its carry bag when not in use to protect it from dust and physical damage.
• Avoid exposing the device to extreme temperatures, humidity, or direct sunlight.
• Protect the optical ports (OPM, VFL) from dust and debris by keeping them capped when not in use.

6.2 Battery Maintenance

• Recharge the battery when the low battery indicator appears to ensure optimal performance and prolong battery life.
• If the device will not be used for an extended period, charge it periodically (e.g., every 3 months) to prevent deep discharge.

7. Troubleshooting

7.1 Cable Continuity Test Issues

• No reading or 'Open Circuit': Check if the cable is properly connected to both the Transmitter and Receiver. Inspect the cable for physical damage or improperly crimped connectors.
• 'Short Circuit' indication: This means two or more wires are touching. Inspect the cable and connectors for damage or faulty wiring.
• 'Cross Connection' indication: This means wire pairs are swapped. Verify the wiring standard (e.g., T568A/B) and ensure consistent crimping.

7.2 No Signal During Scanning

• Ensure the Transmitter is in SCAN mode and the cable is connected.
• Verify the Receiver is powered on and its SCAN function is active.
• Adjust the sensitivity of the Receiver if available (not explicitly mentioned but common for cable tracers).

7.3 Optical Power Meter (OPM) or Visual Fault Locator (VFL) Not Working

• Ensure fiber optic cables are clean and properly connected to the respective ports.
• Check if the correct wavelength is selected for OPM measurements.
• Verify the VFL laser is activated in the menu.

7.4 Safety Protection

The NF-8518 features Anti-burnt 60V safety protection on its RJ45 ports. If an abnormal high voltage (up to 60V) is detected, the protection mechanism will instantly activate to cut off hazardous currents, safeguarding the device.
