5. Instruccions de funcionament

5.1 Circuit Breaker Identification

This function helps locate the correct circuit breaker for a specific outlet or fixture.

1. Connecteu el transmissor: Plug the transmitter into the electrical outlet or fixture you wish to trace. Use the appropriate adapter (3-prong to 2-prong, light socket, or alligator clip) if necessary. Ensure the circuit is energized (90-230V AC).
2. Activate the Receiver: Enceneu el receptor.
3. Scan the Breaker Panel: Slowly scan the receiver along the circuit breakers in the electrical panel.
4. Identify the Breaker: The receiver will emit an audible beep and display increased signal strength on its LCD screen when it detects the correct circuit breaker. The LED indicator on the receiver will also flash.
5. Ajustar la sensibilitat: If multiple breakers show a signal, adjust the sensitivity level on the receiver (0-9 levels) to narrow down the detection to the strongest signal, indicating the correct breaker.

5.2 GFCI Outlet Testing

The transmitter can test GFCI (Ground Fault Circuit Interrupter) outlets and diagnose common wiring faults.

1. Connecteu el transmissor: Insert the transmitter directly into the GFCI outlet to be tested.
2. Observe Indicators: The LCD screen and indicator lights on the transmitter will display the wiring status.
   • Llum verda: Indicates correct wiring.
   • Llum vermella: Indicates an error or damage. The LCD will show specific fault codes (e.g., Missing Ground, Missing Neutral, Open Hot, Live/Neutral Reversed, Live/Ground Reversed).
3. Perform GFCI Trip Test: Press the "GFCI" button on the transmitter. A working GFCI outlet should trip, cutting power to the outlet. Reset the GFCI outlet after testing.

5.3 Vol. sense contactetage (NCV) Detecció

The receiver can detect AC voltage without direct contact, enhancing safety when working with electrical systems.

1. Activate NCV: Turn on the receiver. The NCV function is typically active by default or can be toggled with a dedicated button.
2. Approach Voltage Font: Bring the tip of the receiver close to an insulated wire, outlet, or other potential AC voltage font.
3. Detectar Voltage: Si AC voltage is present, the receiver will emit an audible beep and its LED indicator will flash. The intensity of the beeping and flashing may increase as you get closer to the voltage font.
