• Port Flashing and Identification: Quickly identifies network cable ports by flashing indicator lights on the connected device, displaying port information like operating rate, duplex mode, and negotiation settings.

Setup

Charging the Device

The NF-8506 main unit and remote unit are equipped with rechargeable Lithium Metal batteries. Use the provided USB charging cable to charge both units. Connect the Type-C end of the cable to the charging port on the device and the USB-A end to a compatible USB power adapter (not included).

Powering On/Off

To power on the main unit, press and hold the power button (usually marked with a circle and vertical line) located below the screen. To power off, press and hold the same button until the device shuts down. The remote unit typically has a rotary switch or a dedicated power button.

Operating Instructions

1. Cable Continuity Test

This test verifies the integrity of network cables, identifying open circuits, short circuits, and crossovers.

• From the main menu, select "CONT" (Continuity).
• Connect one end of the RJ45 or RJ11 cable to the "QC/CONT" port on the main unit.
• Connect the other end of the cable to the remote unit's RJ45 port.
• Press "OK" on the main unit to start the test. The screen will display the wiring map and indicate any faults.

2. TDR Cable Length Measurement

Utilizes Time Domain Reflectometry to accurately measure cable length and locate breaks.

• From the main menu, select "Length".
• Connect one end of the cable to the "Length/Flash" port on the main unit. The other end should be open (not connected to anything).
• Press "OK" to initiate the measurement. The screen will display the length for each pair.

3. PING Tester + IP Scanner

Tests network connectivity and scans for active IP addresses on the network.

• From the main menu, select "PING" for Ping test or "IP Scan" for IP scanning.
• Connect the main unit to the network via the RJ45 port.
• For PING test, enter the target IP address and press "OK".
• For IP Scan, define the IP range and press "Scan". The device will list active IP addresses.

4. PoE Tester

Identifies Power over Ethernet (PoE) presence, voltage, and standard.

• From the main menu, select "PoE".
• Connect the main unit to a PoE-enabled port or device.
• The screen will display PoE voltage, polarity, and standard (e.g., IEEE 802.3af/at).

5. Network Rate Test

Assesses the network speed and duplex mode of connected ports.

• From the main menu, select "Switch" (for Switch Test) or "PING" (for Network Speed Test).
• Connect the main unit to the network port.
• The device will display the detected network rate (e.g., 10M/100M/1000M) and duplex mode (Full Duplex/Half Duplex).

6. Port Flashing and Identification

Helps locate connected cables by causing the corresponding port's indicator light to flash.

• From the main menu, select "Port Flash".
• Connect the main unit to the network port you wish to identify.
• The device will send a signal causing the connected port's LED on the switch or router to blink, allowing for easy identification.

7. Cable Toner (Scan Function)

Used to trace and locate cables within bundles or walls using the remote unit.

• From the main unit, select "Scan". Choose between "Digital Mode" (for live networks) or "Analog Mode" (for non-live cables).
• Connect the cable to be traced to the main unit's RJ45 scan port.
• Turn on the remote unit and adjust its sensitivity dial.
• Move the remote unit's probe along the suspected cable path. A louder tone indicates proximity to the cable.

8. Optical Power Meter (OPM)

Measures the optical power of fiber optic cables.

• From the main menu, select "OPM".
• Remove the protective cap from the OPM port on the main unit.
• Connect the fiber optic cable to the OPM port. The device will display the optical power in dBm.
• Supported wavelengths: 850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm.

9. Visual Fault Locator (VFL)

Emits a visible red laser light into a fiber optic cable to quickly locate breaks, bends, or poor connections.

• From the main menu, select "VFL".
• Remove the protective cap from the VFL port on the main unit.
• Connect the fiber optic cable to the VFL port.
• Observe the cable for any visible red light leakage, indicating a fault.
• The VFL output is 10mW.

10. QC Test (Quality Control Test)

This test assesses the quality of RJ45 crimps, ensuring proper contact for all 8 pins.

• From the main menu, select "QC Test".
• Insert the RJ45 connector into the designated QC test port on the main unit.
• The screen will display checkmarks for pins making good contact and crosses for faulty connections.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents. For optical ports, use specialized fiber optic cleaning tools.
• Battery Care: Recharge the device regularly, especially if it will be stored for an extended period, to maintain battery health. Avoid fully discharging the battery.
• Storage: Store the device in its protective cloth bag in a cool, dry place away from direct sunlight and extreme temperatures.
• Port Protection: Always keep protective caps on optical ports (OPM, VFL) when not in use to prevent dust and damage.
