5. Setup and Basic Operation

Before using the NF-488, ensure batteries are installed. The device is powered by 1 AA battery (included). Press the power button to turn on the unit. Use the navigation buttons to select different test modes on the LCD screen.

6. Operating Instructions

6.1. Power / Voltage / Current Testing

This function allows you to measure the voltage, current, and power between a power source and a connected device.

1. Connect the AC adapter (power source) to the "DC IN" port of the NF-488.
2. Connect the DC-DC cable adapter into the "DC OUT" port of the NF-488.
3. Connect the other end of the DC cable into the DC port of the device you wish to test (e.g., a camera).
4. On the NF-488 menu, navigate to and select "POWER".
5. The screen will display the voltage, current, and power readings.

6.2. PoE Testing

This mode identifies PoE standards, power supply polarity, and jumper methods from a PoE switch.

1. Connect one end of a LAN cable into the "PoE Test" port of the NF-488.
2. Connect the other end of the LAN cable into a PoE switch.
3. On the NF-488 menu, navigate to and select "PoE".
4. Press "OK" to start testing. The device will display PoE details such as Endspan and voltage (e.g., IEEE 802.3at, 53.5VDC).

6.3. RJ45 Cable Continuity Testing

This function checks for open circuits, short circuits, and crossovers in network cables, including shielded wires.

1. Connect one end of the LAN cable into the "RJ45" port on the main NF-488 unit.
2. Connect the other end of the LAN cable to the "WIREDMAP" remote module.
3. On the NF-488 menu, navigate to and select "CONT" (Continuity).
4. The LCD screen will display the wiring status, indicating any faults such as open, short, or cross connections.

7. Maintenance

To ensure the longevity and accuracy of your NOYAFA NF-488 POE Cable Tester, follow these maintenance guidelines:

• Keep the device clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Avoid exposing the device to extreme temperatures, humidity, or direct sunlight.
• Store the device in its protective carrying pouch when not in use to prevent physical damage.
• Remove batteries if the device will not be used for an extended period to prevent battery leakage.
• Do not attempt to disassemble or repair the device yourself. Refer to qualified service personnel for any repairs.

8. Troubleshooting

If you encounter issues with your NF-488, consider the following common troubleshooting steps:

• Device not powering on: Check battery installation and ensure batteries have sufficient charge. Replace if necessary.
• Inaccurate readings: Ensure all cable connections are secure and correctly inserted into the designated ports for the selected test mode. Verify that the cables themselves are not faulty.
• Screen not displaying: Check battery level. If the screen is dim, press the backlight button.
• No PoE detection: Confirm that the connected switch is indeed a PoE switch and that PoE is enabled on the port. Ensure the cable is correctly connected to the "PoE Test" port.
• Continuity test errors: Ensure the remote wiremap module is properly connected to the other end of the cable. Check for physical damage to the cable or RJ45 connectors.

For persistent issues, refer to the official NOYAFA support resources or contact customer service.
