Slide the Stud Sensor 150 slowly across the surface in a straight line.
As it detects a stud, the red LED's will go on.

When it detects the stud edge, the
top LED will go 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.

The midpoint of the two marks indicates the stud
center.
Detecting Live AC Wires
10
The live wire red LED will illuminate and the Stud
Sensor 150 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.
9
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 fl oor 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
7
closer together or of a different width may not be a stud.
OPERATING TIPS
The Stud Sensor 150 is designed for use only on interior surfaces.
Prevent Interference
To ensure best performance from the Stud Sensor 150, keep your free hand at
least 6 inches away from the unit and wall surface while testing or scanning
surfaces.
Conventional Construction
Doors and windows are commonly constructed with additional studs and
headers for added stability. The Stud Sensor 150 detects the edge of these
8
double studs and solid headers as a single, wide stud.
Surface Differences
The Stud Sensor 150 will scan through common building materials, Including:
• Gypsum drywall
• Plywood sheathing
• Hardwood fl oors
• Linoleum over wood
• Wallpaper
The sensor cannot scan through:
• Carpeting
• Foil faced materials
• Ceramic tile
• Cement or concrete
10
• Metal & plaster walls
Wallpaper
There will be no difference in the function of the Stud Sensor 150 on
surfaces covered with wallpaper or fabric unless the coverings used
contain metallic foil or fi bers.
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.
IMPORTANT SAFETY NOTICE
Insure proper detection of live wires. Always hold the Stud Sensor 150 in the
handle area only. Grasp between fi ngers and thumb while making contact with
your palm.
