Operating Instructions
Stud Scan
• SelectSTUD SCAN mode and place the instrument against the wall.
Press and hold TEST button until the unit gives two short beeps. Slowly
move the unit sideways across the wall while pressing and holding the
TEST button.
• Whenthecenterbarappears,stopmoving.Itmeansthisunithas
detected an edge of a stud. Mark this spot at the groove.
• Continuemovingsidewaysacrossthewalluntilthecenterbarturns
off,andthen,stillholdingthebutton,reversedirectionandlocateother
edge by using the same procedure. The midpoint between the two
marks is the center of the stud.
Error correction:IftheLCDstartsblinkingandbeeping,moveoverafew
inches and start again.
Notes
• Thestuddetectioncanbecarriedoutnormallyonwall-paperedwalls.
However,itmaynotfunctiononsometypesoffoilbackedormetallic
fabric surfaces.
• Ifbychancetheunitisplacedoverawallbattenorstudtostart,the
center bar will not appear when an edge of batten or wall stud is under
the unit.

Operating Tips
Conventional Construction
Doors and windows are commonly constructed with additional studs and
headers for added stability. This unit detects the edge of these double
studs and solid headers and emits and holds an audio signal as it crosses
over them.
Surface Differences
Wallpaper: there will be no difference in the function of the stud sensor
on surfaces covered with wallpaper or fabric unless the coverings contain
metallic foil or bers.
Plaster and Lath:unlesstheplasterandlathisexceptionallythickorhas
metalmeshinit,therewillbenoproblemwiththeunitfunctioningproperly.
Ceiling or Textured Surfaces: when dealing with a rough surface such as
asprayedceiling,placeapieceofcardboardundertheunitwhenscanning
the surface. Run through the calibration technique described earlier with
thepieceofcardboardbetweenthestudsensorandthesurface.Also,itis
particularly important in this application to remember to keep your free hand
away from the unit.

automatically.Toturnitonagain,presstheTEST button for about 2 seconds.
Note: Detection depth and edge detection may vary due to moisture
contentofmaterials,walltexture,paint,etc.
Battery Replacement
Whenthe“ ”symbolappears,itmeansthatthebatteryislowand
should be replaced.
