GOTMEET Stud Finder NF-5105 Instruction Manual

1. Important Safety Information

Please read and understand all instructions before operating the GOTMEET Stud Finder NF-5105. Failure to follow these instructions may result in electric shock, fire, and/or serious injury.

• Always assume that live AC wires are present in the wall. Exercise extreme caution when scanning near electrical outlets, switches, or fixtures.
• Do not rely solely on the stud finder to locate live AC wires. Always turn off power to the area you are working on at the circuit breaker before drilling or cutting into walls.
• This device is designed for indoor use on common wall materials. Performance may vary on irregular or very thick surfaces.
• Keep the device dry. Do not expose it to moisture or extreme temperatures.
• Do not attempt to open or modify the device. There are no user-serviceable parts inside.

4. Setup

4.1 Charging the Device

The GOTMEET Stud Finder NF-5105 is equipped with a built-in 390mAh rechargeable Lithium Polymer battery. Before first use, or if the battery indicator on the display shows low power, charge the device.

1. Locate the Type-C charging port on the side of the device.
2. Connect the provided Type-C USB cable to the charging port and the other end to a standard USB power adapter (not included) or a computer USB port.
3. The battery indicator on the display will show charging status. A full charge typically takes a few hours and provides up to 5 hours of continuous operation.

4.2 Powering On/Off

• To power on: Press and hold the Power Button (①) until the display illuminates.
• To power off: Press and hold the Power Button (①) until the display turns off.

4.3 No Calibration Required

This device features automatic calibration. Simply press and hold the desired mode button to begin scanning. No manual calibration steps are necessary.

5. Operating Instructions

For optimal results, ensure the wall surface is dry and free from excessive dust or debris. Hold the device flat against the wall and move it slowly.

5.1 General Scanning Procedure

1. Turn on the device using the Power Button.
2. Select the desired detection mode (Wood, Metal, or AC Wire) by pressing the corresponding button.
3. Place the device flat against the wall surface. Ensure your hand is not covering the sensor area.
4. Slowly slide the device horizontally across the surface. The display will show signal strength and object indicators.
5. When an object is detected, the signal strength will increase, and the display will indicate the object's type and proximity. The voice indicator will also provide an audible alert.
6. To find the center of an object, continue scanning past the peak signal, then reverse direction. The device will indicate the center with a specific icon and sound.

5.2 Wood Scan Mode

This mode is used to detect wood studs, light steel joists, nails, and conduits.

• Press the Wood Detection button.
• Scan the wall slowly. The device can detect wood objects up to 1.18 inches (30 mm) deep.
• The display will show a 'STUD' icon and signal strength when a wood object is found.

5.3 Metal Scan Mode

This mode detects magnetic metals (e.g., steel bars, iron) and non-magnetic metals (e.g., copper pipes, wires).

• Press the Metal/AC Wire Detection button until 'METAL' mode is active.
• Scan the wall slowly. The device can detect magnetic metals up to 3.94 inches (100 mm) and non-magnetic metals up to 3.15 inches (80 mm) deep.
• The display will show a 'METAL' icon and signal strength. It may also indicate 'Fe' for ferrous metals.

5.4 AC Wire Scan Mode

This mode is used to detect live, unshielded electrical wiring.

• Press the Metal/AC Wire Detection button until 'AC' mode is active.
• Scan the wall slowly. The device can detect live AC wires up to 2 inches (50 mm) deep.
• The display will show an 'AC' icon and a lightning bolt symbol when live wires are detected.
• Important: The device will always detect and indicate live AC wires in all modes for safety.

7. Troubleshooting

If you encounter issues with your stud finder, refer to the following common problems and solutions:

• Inaccurate Readings:
  • Ensure the device is held flat against the wall and moved slowly.
  • Avoid scanning over wet paint, wallpaper, or highly textured surfaces, which can affect accuracy.
  • Check for external interference from strong electromagnetic fields.
• Device Not Powering On:
  • Ensure the battery is sufficiently charged. Connect the device to a Type-C charger.
  • Press and hold the Power Button firmly for a few seconds.
• No Detection:
  • Verify that the correct detection mode is selected for the object you are searching for.
  • Ensure the device is in direct contact with the wall surface.
  • The object may be deeper than the maximum detection depth for the selected mode.

If problems persist, please contact customer support.
