Step 2: Scanning walls

 

• Move the scanner slowly along the wall. Do not lift the instrument or apply additional pressure;
• Note: If you shake or lift the instrument carelessly, you need to recalibrate it.

 

Step 3: Find the center of the target

 

• The progress bar on the screen changes with the distance of the object;
• When the signal is full, the indicator light flashes and a ticking sound is emitted, meaning that the center of the object has been found.

Calibration the Tool Correctly

Short press the Power Button, the stud finder automatically enters the metal detection function mode. At this time, if there is a signal display on the display screen without interference, it means that calibration is required.

Note: In AC/Metal mode, put it in the air to calibrate it;

In stud/deep mode, put it on the wall where you want to detect to calibrate it

NOTE:

●Sometimes due to various environmental factors, the stud finder may not be able to calibrate automatically, and a wrong alarm signal may appear, please calibrate manually.

●If the detector has just been calibrated on the wooden stand, you need to move the tool out of the range of the wooden stand and detect the wooden stand again.

● If you are receiving erratic scan results, it may be due to moisture, humidity inside the wall cavity or drywall, or recently applied paint or wallpaper that has not fully dried. While moisture may not always be visible, it can interfere with the tool's sensors. Please allow the walls to dry for a few days.

●For some environmental factors or uneven surfaces, it is difficult to detect wooden nails using the wood studs detection mode. It may be easier to find these items by changing the metal detection mode to locate the nails that hold the material to the wood.

● Depending on the proximity of wires or pipes to the wall, the stud finder can detect them in the same way as wood studs. Care should always be taken when nailing, cutting or drilling holes in walls, floors and ceilings that may contain these items.
