Getting started
Press the Power/Back button (4) and hold it for 3s to turn the device on/off.
Calibration must be done each time a new mode is selected.
Sensitivity setting
You can set the sensitivity in the three detection modes separately. Press the Set/+ button (8) to enter the menu. Select “Sensitivity setting”. Press the Sound/– button (3) and the Set/+ button (8) to adjust the sensitivity level (high/middle/low), press the Metal detection/Confirm button (6) to select the setting item, and press the Power/Back button (4) to return.
Metal detection mode
The metal detection mode is used for the detection of hidden objects made of ferrous and non-ferrous metals. The metal detection mode is set by default.
Calibration
- Press the Set/+ button (8) to enter the menu. Select “Metal detection calibration”.
- Place the device flat against the target surface.
- Press the Metal detection/Confirm (6) button to start the calibration. The calibration will be carried out automatically. When the white part of the display becomes dark, the calibration is completed.
- Remove the device from the surface and press Power/Back button (4) to exit the calibration mode.
Usage
- Complete the calibration and place the device flat against the surface to be tested.
- Slowly move the detector across the surface in the direction you want to scan.
- When the device detects a metal object, the screen will display the icon (non-ferrous metal) or (ferrous metal), the value of the distance to the target, and the signal strength indication. The device will emit a sound. The closer the device is to the object, the stronger the signal will be.
- When the signal is the strongest, the center mark (14) lights up. Move the device to locate the object according to the signal intensity.
! If you’re receiving erratic scanning results, it may be a result of humidity, moisture within the wall cavity or drywall, or recently applied paint or wallpaper that isn’t fully dried.
Stud detection mode
The device can scan the surface for wooden and/or metal studs.
Calibration
Automatic calibration
- Press the Stud detection button (7) to enter the stud detection mode.
- Place the device flat against the target surface.
- Press the Stud detection button (7) to start calibration. The calibration will be carried out automatically. When the white part of the display becomes dark, the calibration is completed.
- Remove the device from the surface and press Power/Back button (4) to exit the calibration mode.
If the device does not search for wooden/metal objects after automatic calibration, you need to calibrate the device manually.
Manual calibration
- Press the Stud detection button (7) to enter the stud detection mode.
- Place the device flat against the target surface. When the display becomes dark, press the Stud detection button (7) to force the device to calibrate.
- Slowly move the detector across the surface in the direction you want to scan. When the signal is the strongest, the center mark (14) lights up.
- Remove the device from the surface and press the Power/Back button (4) to exit the calibration mode.
Usage
- Press the Stud detection button (7) to enter the stud detection mode.
- Complete the calibration and place the device flat against the surface to be tested.
- Slowly move the detector across the surface in the direction you want to scan.
- If a stud is detected, the screen will display the wooden/metal stud icon
, the value of the distance to the target, and the signal strength indication. The device emits a sound. The closer the device to the object, the stronger the signal.
AC detection mode
This mode is used only to detect live wires.
Calibration
- Press the AC wire detection button (2) to enter the AC detection mode.
- Place the device flat against the target surface.
- Press the AC wire detection button (2) to start calibration. The calibration will be carried out automatically. When the white part of the display becomes dark, the calibration is completed.
- Remove the device from the surface and press the Power/Back button (4) to exit the calibration mode.
Usage
- Complete the calibration and place the device flat against the surface to be tested.
- Slowly move the detector across the surface in the direction you want to scan.
- When the device detects a live wire, the screen will display the live wire icon , the value of the distance to the target, and the signal strength indication. The device emits a sound. The closer the device to the object, the stronger the signal. You can reduce the sensitivity of the device multiple times to narrow the search area even more and locate the live wire with greater accuracy.
