The Magnet (NUMBER 18) is an additional function. it can be
used to to confirm the metal position twice.But please note, this
function is only a reference for the second confirmation of the
location of the metal or metal stud, not as a basis for judgment.
Note: The target size and distance determine the size of the magnetic
force. If the distance is too far or the metal is too small, the magnetic
force may not change.
Work Principle
Because the stud finders are looking for a change in density behind wall
in Stud Scan Modes and Deep Scan Modes, not a particular material. The
detector will react to metal studs the same as it would for wooden
studs. We can only hang things to wooden stud and can’t drill to the metal
stud.
It is important to Confirm it is a metal stud or wooden stud before you act
ually drill to the wall.After you detect the center of a stud, Please Put the
bottom magnet on the center mark to recheck whether it is metal or wood
stud, or Use Metal Scan Mode (refer to the description of Metal Scan Mode
below) to determine whether the previous reading in Stud scan was a
wooden stud or metal stud.
Stud Scan Mode 1
Use this stud scan mode to find the center and edges of wood or metal
studs up to 1
⁄
2 in. (12 mm) deep. For best results, always start in this
mode when looking for studs.
Step 1:
Press the mode button to choose the
“stud mode”
Step 2
：
Put the scanner on the wall and Press the Scan Button on the
side of the tool to calibrate. After a short beep sounds, confirming
calibration is complete.
Note: Be sure not to move the scanner while calibrating.
Calibrate the tool on the wall before every scan.
Step3:
Move it flat against the wall to scan.
Note: If it finds metal or wooden stud, the screen will show as the picture
and it beeps.
If it finds nothing, please repeat the above steps ( calibrate it and move it
to scan)
