Informazioni sulla sicurezza
Read and understand all safety warnings and operating instructions before using this product. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Always assume circuits are live until verified otherwise.
- Non utilizzare il dispositivo se appare danneggiato o non funziona correttamente.
- Ensure proper connection of test leads to avoid short circuits or damage to the device.
- Utilizzare dispositivi di protezione individuale (DPI) adeguati quando si lavora con impianti elettrici.
- The NCV function is for quick checks; always confirm with a known voltage source if possible.
- Tenere il dispositivo lontano dall'acqua e da temperature estreme.
Impostare
Before first use, ensure both the transmitter and receiver are fully charged using the provided charging cable.
- Ricarica: Connect the charging cable to the charging port on both the transmitter and receiver, then connect to a suitable USB power source. The battery indicator will show charging status.
- Accensione/spegnimento: Per accendere o spegnere il trasmettitore e il ricevitore, tenere premuto il pulsante di accensione.
- Collegamento del trasmettitore: For circuit tracing, connect the transmitter to the circuit you wish to trace. Use the test leads and alligator clips for direct connection to wires or terminals. For underground tracing, connect one lead to the wire and the other to the grounding rod inserted into the earth.
Istruzioni per l'uso
Circuit Tracing (Live & De-energized Wires)
- Collegare il trasmettitore: Connect the transmitter to the circuit as described in the Setup section. Ensure a secure connection.
- Accensione: Accendi sia il trasmettitore che il ricevitore.
- Adjust Transmitter Intensity: On the transmitter, select the appropriate transmission intensity level (3 levels available) based on the environment and desired detection depth. Higher intensity for deeper or longer traces.
- Scan with Receiver: Hold the receiver and move it along the suspected path of the wire. The receiver will provide audible beeping alerts and a visual signal strength bar on its display.
- Adjust Receiver Sensitivity: Use the 8-level sensitivity adjustment on the receiver. Start with higher sensitivity for a broad scan, then reduce it for precise positioning and to minimize interference when nearing the target wire.
- Individuare l'obiettivo: Follow the strongest signal indication (both audio and visual) to pinpoint the exact location of the wire, break, or short circuit.
Volume senza contattotage (NCV) Rilevamento
- Attiva NCV: On the receiver, press the NCV button to activate the non-contact voltage modalità di rilevamento.
- Scansiona per Voltage: Bring the tip of the receiver close to the wire or outlet you want to test.
- Interpret Indication: The receiver will provide audible and visual alerts (e.g., flashing LED, changing display) if live AC voltage viene rilevato.

Funzioni del multimetro digitale
The transmitter unit integrates digital multimeter capabilities:
- Connect Test Probes: Insert the test pen and test clip into the appropriate ports on the transmitter.
- Seleziona la funzione: Use the mode selection buttons on the transmitter to cycle through available measurement functions: AC/DC voltage, continuity, resistance, current, and frequency.
- Eseguire la misurazione: Apply the test probes to the circuit or component you wish to measure. The reading will be displayed on the transmitter screen.

Risoluzione dei problemi
Se riscontri problemi con il tuo NF-8301, fai riferimento ai seguenti problemi comuni e alle relative soluzioni:
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Nessun segnale rilevato | Transmitter not powered on; low battery; incorrect connection; signal too weak. | Ensure transmitter is on and charged. Check connections. Increase transmitter intensity. Adjust receiver sensitivity. |
| Segnale debole o incoerente | Low battery; high interference; signal attenuated by material. | Charge devices. Reduce receiver sensitivity to filter noise. Move closer to the wire. Ensure proper grounding. |
| False readings or multiple signals | High receiver sensitivity; proximity to other electrical sources. | Decrease receiver sensitivity for precise targeting. Move away from known interference sources. |
| Digital Multimeter not functioning | Incorrect mode selected; test probes not connected; low battery. | Verify correct measurement mode. Ensure test probes are securely connected. Charge transmitter. |
