Stanley Stud Sensor 100
The Stud Sensor 100 uses electronic signals to locate the edges of studs, joists or live AC wires through drywall or other common building materials. Once the edge of a stud has been detected, the Stud Sensor 100 displays red LED’s and sounds an audible tone. A marking channel allows you to easily note the stud edges on the wall.
Note: Read all instructions prior to operating the Stud Sensor 100 and DO NOT remove any labels from the tool.
OPERATING INSTRUCTIONS
Battery
1Open door on back of unit and connect a 9 volt battery (not included) to clip. Put battery back into case and close back battery door.
Note: Recommend to replace a new 9 volt battery when low battery - flashing green LED.
Usage
Detecting Wood / Metal Studs
2Hold the Stud Sensor 100 flat against
the surface, making firm contact.
3Press in and hold the activation button. The green and top red LED will light. 4 When the red LED goes off, the unit is calibrated. 5 Keep holding the activation button during all of the following procedures.
Note: 3 The unit cannot be moved
before calibration is complete.
2 While | calibrating, the Stud Sensor 100 |
must not | be placed directly over a stud, |
dense material such as metal, or over a wet | |
or newly painted area, or it will not properly | |
on and an audible tone will sound. Use the marking channel located at the top of the unit to mark the stud edge. 7 Repeat the above steps from the other side of the stud. Coming from the opposite direction, mark the other edge of the stud. 8 The midpoint of the two marks indicates the stud center.
Detecting Live AC Wires
10The live wire red LED will illuminate and the Stud Sensor 100 sounds an audible tone, warning when in the proximity (typically within 4” to 18” along the surface) from a live wire.
Note: Static electrical charges that can develop on drywall and other surfaces will spread the voltage detection area many inches on each side of the actual electrical wire. To aid in locating the wire position, scan holding the unit ½” away from the wall surface or place your other hand on the surface approximately 12” from sensor.
Warning: Shielded wires or wires in metal conduits, casings, metallized walls or thick, dense walls will not be detected. Always turn off AC power when working near wiring.
Cautions on Operating
You should always use caution when nailing, cutting and drilling in walls, ceilings and floor that may contain wiring and pipes near the surface. Always remember that studs or joists are normally spaced 16 inches or 24 inches apart and are 1½ inches in width. To avoid surprises, be aware that anything closer together or of a different width may not be a stud.
OPERATING TIPS
Conventional Construction
Doors and windows are commonly constructed with additional studs and headers for added stability. The Stud Sensor 100 detects the edge of these double studs and solid headers as a single, wide stud.
Surface Differences
The Stud Sensor 100 will scan through common building materials, Including:
•Gypsum drywall
•Plywood sheathing
•Hardwood floors
•Linoleum over wood
•Wallpaper
The scanner cannot scan through:
•Carpeting
•Foil faced materials
•Ceramic tile
•Cement or concrete
•Metal & plaster walls
Wallpaper
There will be no difference in the function of the Stud Sensor 100 on surfaces covered with wallpaper or fabric unless the coverings used contain metallic foil or fibers.
Ceilings
When dealing with a rough surface such as a sprayed ceiling, utilize a piece of cardboard when scanning the surface. Run through the calibration technique described earlier with the piece of cardboard too, to assure best performance of the unit. Also, it is particularly important in this application to remember to keep your free hand away from the unit.
Note: The thickness, density and moisture content of the surface material will affect the sensing depth.

Prevent Interference
To ensure best performance from the Stud Sensor 100, keep your free hand at least 6 inches away from the unit and wall surface while testing or scanning surfaces.
IMPORTANT SAFETY NOTICE
Insure proper detection of live wires. Always hold the Stud Sensor 100 in the handle area only. Grasp between fingers and thumb while making contact with your palm.
