3. Setup and Calibration

3.1 Battery Installation

The DEWINNER Wall Detector requires a 9V battery for operation. To install the battery, open the battery compartment located on the back of the unit. Insert a fresh 9V battery, ensuring correct polarity, then close the compartment securely.

3.2 Initial Calibration

For accurate readings, the device must be calibrated before each use and when switching between detection modes. To calibrate:

1. Place the detector flat against the wall surface where you intend to scan. Ensure there are no known studs, metal, or AC wires in the immediate area during calibration.
2. Press and hold the Power Button/Mode Switch Button (located on the side of the unit) until the device powers on and emits a short beep.
3. Keep the device stationary against the wall until the calibration process is complete, indicated by a stable display and another beep.
4. The device is now ready for scanning in the selected mode.

Note: Improper calibration can lead to inaccurate readings. Always calibrate on a clear section of the wall.

4. Operating Instructions

The DEWINNER Wall Detector offers four scanning modes, each optimized for different materials and depths. Select the appropriate mode using the Power Button/Mode Switch Button.

Figure 3: Overview of the four detection modes and their maximum scanning depths.

4.1 Stud Scan Mode

This mode is designed to locate the center and edges of wood and metal studs behind drywall. It detects up to 3/4 inch (19 mm) deep.

1. Select Stud Scan mode.
2. Calibrate the device on a clear section of the wall.
3. Slowly slide the detector horizontally across the surface.
4. The LCD will indicate signal strength, and an audible beep will sound as it approaches a stud. The 'CENTER' indicator will illuminate when the center of the stud is found.

4.2 Deep Mode

For detecting deeper wood and metal studs, this mode extends the scanning depth up to 1 1/2 inches (38 mm).

1. Select Deep Mode.
2. Calibrate the device on a clear section of the wall.
3. Proceed with horizontal scanning as in Stud Scan mode.
4. The display and audio alerts will guide you to the stud's location.

4.3 Metal Scan Mode

This mode is used to detect various metal objects, including rebar, pipes, and metal studs, up to a maximum depth of 2.36 inches (60 mm).

1. Select Metal Scan mode.
2. Calibrate the device on a clear section of the wall.
3. Scan the surface slowly. The device will indicate the presence of metal.

4.4 AC Scan Mode

Designed to detect live unshielded AC wires (110-220V) up to 2 inches (51 mm) deep. This mode is crucial for safety when drilling or cutting into walls.

1. Select AC Scan mode.
2. Calibrate the device on a clear section of the wall.
3. Scan the area slowly. The AC wire warning indicator and an audible alarm will activate upon detecting live AC wires.

Important Safety Note: Always exercise extreme caution when detecting AC wires. The presence of an AC warning indicates live electricity. Disconnect power if possible before proceeding with any work.

6. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the detector in a cool, dry place away from direct sunlight and extreme temperatures. Remove the battery if the device will not be used for an extended period to prevent leakage.
• Protection: While the device is dustproof and splash-resistant (IP65), avoid submerging it in water or exposing it to heavy rain.

7. Troubleshooting

• Inaccurate Readings/False Positives: Ensure the device is properly calibrated on a clear section of the wall before scanning. Avoid scanning over recently painted or damp surfaces, as moisture can interfere with detection.
• No Detection: Check the battery level. If the low battery indicator is on, replace the 9V battery. Ensure you are using the correct detection mode for the material you are trying to locate.
• Difficulty Understanding Instructions: Refer to the detailed operating instructions in Section 4. Practice on known objects (e.g., a piece of wood or metal) to familiarize yourself with the device's feedback.
• Device Not Turning On: Verify the battery is correctly installed and fully charged. Press and hold the Power Button/Mode Switch Button firmly.
