3. Configurare
3.1 Instalarea bateriei
The NF-308 requires two 9V batteries for operation. These are typically included with the product. To install or replace batteries:
- Localizați compartimentul bateriilor pe spatele unităților emițător și receptor.
- Deschideți capacul bateriei.
- Insert the 9V batteries, ensuring correct polarity (+/-).
- Închideți bine capacul bateriei.
3.2 Pornirea inițială
Press the power button on the Emitter unit to turn on the device. The LCD screen will illuminate, displaying the main menu options.
4. Instrucțiuni de utilizare
The NF-308 offers multiple testing modes accessible via the main menu. Use the arrow buttons to navigate and the 'OK' or 'Scan' button to select.
4.1 WireMap Test (Cable Continuity)
This mode checks for open circuits, short circuits, cross circuits, and reverse connections in network, telephone, and coaxial cables.
- Connect one end of the cable to the appropriate port (RJ45, RJ11, or BNC) on the Emitter.
- Connect the other end of the cable to the Remote Adapter (for remote testing) or directly to the Emitter's corresponding port (for local testing).
- Select 'WireMap' from the Emitter's menu.
- Press the 'Scan' button to begin the test. The LCD will display the wiring status (e.g., 'Pass', 'Open', 'Short').

4.2 Pair & Length Test (Cable Length Measurement)
This mode measures the length of network cables and identifies the distance to a fault.
- Connect one end of the cable to the 'MAIN' port on the Emitter.
- Ensure the other end of the cable is open (not connected to anything).
- Select 'Pair&Length' from the Emitter's menu.
- Press the 'Scan' button. The LCD will display the length for each pair and the distance to any detected open or short circuit.

4.3 Coax/Tel Test
This mode is specifically for testing coaxial and telephone cables.
- Connect the coaxial or telephone cable to the respective BNC or RJ11 port on the Emitter.
- Connect the other end to the Remote Adapter or leave it open as required by the test.
- Select 'Coax/Tel' from the Emitter's menu.
- Press the 'Scan' button to perform the test.
4.4 Port Flash Function
The Port Flash function helps locate a specific network cable connected to a switch or router by causing its corresponding port LED to flash.
- Connect one end of the network cable to the 'PORT FLASH' port on the Emitter.
- Connect the other end of the cable to a port on the active switch or router.
- Select 'Port Flash' from the Emitter's menu.
- The Emitter will send a signal, causing the LED on the connected switch/router port to flash, allowing for easy identification.

4.5 Wire Tracing (Using the Receiver)
The Receiver unit is used to trace cables and locate them within bundles or walls.
- Connect the cable to be traced to the Emitter.
- Porniți unitatea receptorului.
- Adjust the sensitivity on the Receiver as needed.
- Move the Receiver's probe along the suspected path of the cable. The Receiver will emit an audible tone, which will be strongest when it is directly over the cable being traced.

The video shows the device performing cable continuity tests, measuring cable fault distances, and using the wire tracer function to identify cables connected to a network switch. This illustrates the practical application of the device's core functions.
4.6 DC Voltage Măsurare
The NF-308 can measure DC voltage într-un interval de la 0.5V la 60V.
- Connect the test leads (if provided, or use appropriate connectors) to the voltage measurement points on the Emitter.
- Conectați celelalte capete ale sondelor de testare la borna de curent continuu.tage sursa.
- Selectați volumultage measurement function from the Emitter's menu. The LCD will display the measured voltage.
