IntelliSensor" Pro
Multi-depth Stud Finder

IntelliSensor™
Pro (77-255)
The Stanley® Intel liSensor™ Pro uses
electronic signals to locate the position
of studs, joists or live AC wires through
drywall and other common wall
materials. Once the edge of the stud has
been detected, the IntelliSensor™ Pro
LCD display gives visual and audio
indications that allow you to easily
pinpoint the stud's edge position. A
pencil line allows you to quickly note the
location of the stud edges.
The IntelliSensor™ Pro allows the user
to locate wood and metal studs up to
38 mm (1-1/2").
The IntelliSensor™ Pro provides
automatic calibration, auto shut off
and heavy duty ABS construction.
Depth detection selected by side button
for 1/2" (12 mm), 1" (25 mm) and 1-1/2"
(38 mm).
Important: Read all instructions prior to
operating the IntelliSensor™ Pro and DD
NDT remove any labels from the tool.

Operating Instructions
Battery Replacement
Open the battei7 door on back
of unit and connect a 9-volt
battery (not included) to clip. ^
Place battery back into case
and snap battery door on.
Recommend to replace a new 9
volt battery when low battery gattery Door
indicator is on. illustration 4
Calibration
Calibrate the unit on wall before
scanning for wood or metal stud.
Note: While calibrating, the
IntelliSensor^'^ Pro must not be placed
directly over a stud, dense material such
as metal, wet or newly painted areas as
this will prevent the unit from calibrating
properly. If this is done over a wood or
metal stud the unit will give no indication
when moved away from the area. Move
to a different location and try again.
Calibrating
Hold the IntelliSensor™ Pro flat against the
surface, making firm contact. Press and
hold the "ON" button. All indicators on the
LCD are displayed while the unit goes
through its 1 to 3 second calibration cycle.
The word "CALIBRATING" will appear on
the LCD (illustration 2) while the unit is
calibrating to surface. Following the
completion of calibration the unit will
beep, and the word "READY" will be
5

shown on the LCD (illustration 5). The LED
light will then il luminate the keypad depth
mode (1/2" [12 mm] depth default).
IMPORTANT: The unit cannot be moved
before calibration is
complete and "READY"
appears on the LCD and
LED illuminates.

USAGE
Selecting Depth Detection
1. Depress and hold "ON" button once
(Ix) to select 1/2" (12 mm) read depth
detection. The 1/2" (12 mm) mode LED
will illuminate (illustration 3). The unit
will then calibrate, followed by a beep
and a "READY" displayed on the LCD.
2. "Double-click" / Depress and hold ON
button twice (2x) to select 1" (25 mm)
read depth detection. The 1" (25 mm)
mode LED will illuminate (illustration
3). The unit will then calibrate,
followed by a beep and a "READY"
displayed on the LCD.
3. "Triple-click"/ Depress "ON" button
three times (3x) to select 1-1/2"
(38 mm) read depth detection. The
1-1/2" (38 mm) mode LED will il luminate
(illustration 3). The unit will then
calibrate, followed by a beep
and a "READY" displayed on the LCD.
IMPDRTANT: The unit cannot be moved
before calibration is complete and
"READY"

Detecting Wood Studs
1. Slide the unit across the surface in a
straight line. The closer the unit is to
the stud, the more bars will be shown
as illustration 6. When the stud edge
is detected, the Wood indicator and
the edge bar will be shown as
illustration 7 and the unit will sound a
continuous beep.
2. Use indicator graphic (illustration
2&7) and indicator mark (illustration 1)
to locate and define stud edge.
3. Continue sliding past the stud. When
the indicator turns off and the unit
stops beeping the other edge has
been detected.
4. Double check stud location by coming
back from the other direction. Make
additional markings.
5. The midpoint of the marks indicates
the stud centre.

Detecting Live Wires
The live wire red LED lens (illustration 1)
will illuminate, warning when in the
proximity (typically within 10-46 cm [4-
18"] distance) of a live wire. The LCD
screen will then display a live wire icon
(il lustration 2) on the LCD defining full
detection. Maximum depth detection of 5
cm (2").
Static electricity charges that can
develop on drywall and other surfaces
will spread the voltage detection area
many inches to each side of the actual
electrical wire. To aid in locating the wire
position, scan holding the unit 12 mm
(1/2") away from the wall surface or
place other hand on surface
approximately 30 cm (12") from sensor.
Warning; shielded wires or live wires in
metal conduits, casings, metallised
walls or thick, dense walls, will not be
detected. Always turn AC power off
when working near wiring.
The IntelliSensor™ Pro is designed to
detect 110 volts (for USA version) and
230 volts (for European version) AC in live
electrical wires. It will also detect the
presence of live wires exceeding 230
volts.

Cautions on Operating
You should always use caution when
nailing, cutting or drilling in walls,
ceilings and floors that may contain
wiring or pipes near to the surface.
Shielded, dead or non-powered wiring
will not be detected as live wires.
Always remember that studs or joists are
normally spaced 41 cm (16") or 61 cm
(24") apart and are 38 mm (1-1/2") in
width. To avoid surprises, be aware that
anything closer together or of a different
width may be an additional stud, or joist
fire break.
When working near AC electrical wires,
always turn off the power.
Operating Tips
IMPORTANT SAFETY NOTICE
To ensure proper detection of live wires,
ALWAYS hold the IntelliSensor™ Pro in
the handle area only. Grasp between
fingers and thumb while maintaining
contact with your palm.
Conventional Construction
Doors and windows are commonly
constructed with additional studs and
headers for added stability. The
IntelliSensor™ Pro 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 wal lpaper or fabric unless the
coverings contain metallic foil or fibres.
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, use a piece of cardboard
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.
Specifications
Utilising the procedure of scanning and
marking from two sides, IntelliSensor™ Pro
will find the stud centre typically within 0.3
cm (1/8") accuracy for wood and 0.6 cm
(1/4") accuracy for metal.
When measuring a wood or metal stud, it is
recommended the IntelliSensor™ Pro be
used at 30-50% relative humidity.
