6. මෙහෙයුම් උපදෙස්

6.1. Circuit Breaker Finding

1. Plug in the Transmitter: 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. Activate the Receiver: Press and hold the power button on the receiver for a few seconds to turn it on. The receiver will enter "SCAN" mode.
3. සංවේදීතාව සකස් කරන්න: 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. Scan the Breaker Panel: 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. Identify the Breaker: 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. තහවුරු කරන්න: Once identified, turn off the suspected breaker and check if the power to the original outlet/fixture is cut.

2. Check Wiring Status: Observe the LCD display for the initial wiring status (e.g., "CORRECT").
3. Perform GFCI Test: 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. GFCI නැවත සකසන්න: 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. සම්බන්ධතා නොවන වෙළුමtage (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.
