4. Operating Instructions

4.1 Network Cable Tracking Mode

  1. Connect the network cable to be traced to the "Network cable Tracking" port on the Transmitter (NF-825T).
  2. Turn on the Transmitter and set the switch to "SCAN" mode.
  3. Turn on the Receiver (NF-825R) and press the "SCAN" button.
  4. Adjust the sensitivity switch on the Receiver to an appropriate level.
  5. Move the Receiver's probe along the suspected path of the cable. The signal indicators and audible tone will guide you to the target cable.

4.2 Strong Electricity Tracking (Detecting Hidden Wires)

  1. Connect the Transmitter (NF-825T) to the live circuit using the appropriate accessory cables (e.g., multimeter adapter cable with alligator clips).
  2. Set the Transmitter switch to "Live" mode.
  3. Turn on the Receiver (NF-825R) and adjust the sensitivity.
  4. Scan the area where hidden wires are suspected. The Receiver will indicate the presence of live wires through visual and audible signals.

4.3 Socket Test

  1. Plug the Socket Tester (NF-825M) into the electrical outlet you wish to test.
  2. Observe the LED indicators on the Socket Tester. Refer to the table below for interpretation of the LED patterns.
  3. If the GFCI button is present and you wish to test the Ground Fault Circuit Interrupter, press the GFCI button. The circuit should trip if the GFCI is functioning correctly.

4.4 NCV (Non-Contact Voltage) Detection

  1. Turn on the Receiver (NF-825R).
  2. Press the "NCV" button.
  3. Bring the probe end of the Receiver close to an AC voltage source (e.g., live wire, electrical outlet).
  4. The Receiver will indicate the presence of AC voltage through visual (LEDs) and audible signals without direct contact.

4.5 Air Circuit Breaker Tracking Mode

This mode helps identify which circuit breaker controls a specific outlet or circuit.

  1. Plug the Transmitter (NF-825T) into the electrical outlet of the circuit you want to identify.
  2. Ensure the Transmitter is powered on and in the appropriate tracking mode (e.g., "Live" or "SCAN" depending on the specific function).
  3. Go to the circuit breaker panel.
  4. Turn on the Receiver (NF-825R) and adjust its sensitivity.
  5. Move the Receiver's probe along the circuit breakers. The Receiver will emit a strong signal when it detects the correct breaker connected to the Transmitter.

8. User Tips

  • Adjust Sensitivity: For precise tracing, start with a lower sensitivity setting on the Receiver and gradually increase it until a clear signal is detected. This helps to minimize interference from adjacent wires.
  • Environmental Factors: Be aware that thick walls, metal conduits, or other strong electromagnetic fields can affect tracing accuracy and detection distance.
  • Safety First: Always exercise caution when working with live electrical circuits. If unsure, consult a qualified electrician.
  • LED Light Utility: Utilize the built-in LED light on the Receiver for improved visibility in dark work environments, such as behind panels or in crawl spaces.
