5.2. Attaching Adapters (If Needed)

Depending on your testing requirements, attach the appropriate adapter to the transmitter:

• 3-prong to 2-prong adapter: For testing older 2-prong outlets.
• Light socket adapter: For testing light bulb sockets.
• Alligator clip adapter: For direct connection to wires or terminals (use with extreme caution).

6. Instrucións de funcionamento

6.1. Circuit Breaker Finding

1. Conecta o transmisor: Insert the NF-824 transmitter into the electrical outlet or fixture you wish to trace. Ensure it is securely connected. The transmitter's LCD will display the voltage and wiring status.
2. Activar o receptor: Press and hold the power button on the receiver for a few seconds to turn it on. The receiver will enter "SCAN" mode.
3. Axustar a sensibilidade: Use the sensitivity switch on the side of the receiver to set the desired detection level. Start with a lower sensitivity and increase if needed.
4. Escanear o panel de disxuntores: Slowly move the tip of the receiver along the circuit breakers in the electrical panel. Maintain a consistent speed and distance from each breaker.
5. Identificar o interruptor: The receiver will provide visual (flashing light on the tip, signal strength on LCD) and audible (beeping) indications when it detects the correct circuit breaker. The strongest and most consistent signal indicates the target breaker.
6. Verificar: Once identified, turn off the suspected breaker and check if the power to the original outlet/fixture is cut.

6.2. GFCI Outlet Testing

1. Conecta o transmisor: Insert the transmitter into a GFCI-protected outlet.
2. Comprobar o estado do cableado: Observe the LCD display for the initial wiring status (e.g., "CORRECT").
3. Realizar a proba GFCI: Press the "GFCI" button on the transmitter. The GFCI outlet should trip, cutting power to the outlet. The transmitter's display will show the trip time.
4. Restablecer GFCI: Reset the GFCI outlet by pressing its reset button.

Note: If the GFCI does not trip, it may be faulty and should be inspected by a qualified electrician.

6.3. Vol. sen contactotage (NCV) Testing

1. Activate NCV: The receiver automatically enters NCV mode when powered on.
2. Scan for Voltage: Move the tip of the receiver near electrical wires, outlets, or devices.
3. Detectar Voltage: Se AC voltage is present, the NCV indicator light on the receiver's tip will flash, and the LCD will show a signal strength bar. The intensity of the light and the number of bars indicate the strength of the detected voltage.

6.4. Wiring Condition Detection

When the transmitter is plugged into an outlet, its LCD screen provides clear visual feedback on the wiring condition. The red/green indicator lights, combined with details on the large screen, can accurately diagnose 6 common wiring faults:

• Cableado correcto
• Terreo Aberto
• Abrir Neutral
• Abre quente
• Quente/Neutro invertido
• Quente/Terra invertida
