FRANKLIN SENSORS PROSENSOR T13
Congratulations on selecting one of the most
advanced wall sensors on the market. Your ProSensor
T13 incorporates advanced technology that precisely
senses the surface in eleven locations simultaneously,
then instantly identies the location(s) of hidden
object(s). It is easy, fast, and accurate.
SAFETY RULES FOR THE PROSENSOR T13
WARNING: Read all instructions before use. Failure
to follow safety instructions may result in electric
shock, re, and/or serious injury and death.
SAVE THESE INSTRUCTIONS
WARNING: It is possible that there may be wood,
metal, wiring, or other objects behind the surface that
are not detected. The stud nder may also detect
pipes, wires, or other objects that the user may not
want it to detect. The stud nder is designed to detect
any inconsistency but does not identify what type of
inconsistency or object it detects. The illuminated LEDs
may indicate the location of many dierent features
including, but not limited to, studs, beams, water pipes,
gas pipes, wires, an inconsistency in the surface
material or paint, etc.
WARNING: TURN OFF all gas, water, and electric power
before using any drilling or penetrating devices or
equipment including drills, saws, routers, hammers,
nails, screws, etc.
WARNING: The stud nder alone should not be relied
upon exclusively to locate objects behind a scanned
surface. Use other sources of information to help locate
objects. Other sources of information may include, but
are not limited to, construction plans, visible points of
entry of pipes, location of switches and outlets, and
standard 16" and 24" stud spacing practices.
FAILURE TO TAKE THESE AND OTHER NECESSARY
PRECAUTIONS COULD RESULT IN ELECTRIC SHOCK,
FIRE, AND/OR SERIOUS INJURY AND DEATH.
Clean
Before turning on, ensure that the stud nder is clean
and dry. If necessary, wipe the stud nder dry using a
clean cloth. If the detector is wet or dirty it may not
operate properly.
Temperature
If the stud nder is subject to a signicant temperature
change, allow it adjust to the ambient temperature
before using. The entire area of the sensor board
should be at a similar temperature for best operation.
TO OPERATE:
• Hold the stud
nder by the
handle. Do not
touch the detector
outside of the
handle area while
scanning.
• Place the ProSensor T13 rmly
against the surface and press the “on” button.
• With the button depressed, you may immediately begin
scanning the wall (No calibration or tuning is required.)
As you scan, LED lights will immediately display the
location of any hidden objects.
• The “on” button may be pressed before or after placing
the stud nder on the surface to be scanned. The stud
nder will operate if slid across the wall, but no sliding is
required.
• LED lights indicate
the width of
hidden object(s).
• On some surfaces
it may be helpful
to slide the stud
nder up and down
to conrm the
location of a stud.
Handle Hold
When operating the ProSensor T13 the hand should
remain on the handle. Holding the T13 on the sides, or
with fingers close to the Sensor Board, may cause the
unit to work inaccurately.
SENSING THROUGH DIFFERENT MATERIALS:
Moisture
The scanned surface should be clean and dry. Paint and
wallpaper need to be completely dry before scanning for
studs. It may take up to 2 weeks for wallpaper to dry
enough to detect studs.
Foil-Backed Insulation
Although foil covered insulation is not very common,
metal foil can cause inconsistent readings with all
electronic stud nders, including the ProSensor T13.
Metallic Content in Wallpaper
Wallpaper with metallic content can block the detector’s
signals.
Textured Walls and Acoustic Ceilings
The ProSensor T13 is capable of detecting studs through
many textures and surfaces. The unit will however work
most accurately if placed rmly against the attest
portions of the wall. When looking for studs you will
depress the button and slide the unit horizontally across
the wall. For the best results, prior to beginning your
scan, identify a horizontal area that is consistently the
attest.
Lath and Plaster
Irregularities in plaster thickness and variations in
construction materials can make it dicult to locate studs
behind lath and plaster walls. Also, if the plaster has a
mesh reinforcement, the stud nder may not be able to
detect through the metal mesh.
Tile, Flooring, Roong, and Outside of House
The ProSensor T13 works by measuring the density of
material behind the sensors to determine the location of
studs. Due to the variability in the density of materials in
tile, ooring, roong, and on the outside of the house, we
do not recommend the ProSensor T13 for use in these
applications.
STICKERS / DECALS
Do not place decals or stickers, especially those
containing metal, on the sensor board, or on the stud
nder in any place.
DISASSEMBLY / TEFLON PADS
Do not disassemble the stud nder or remove the teon
pads on the bottom. The stud nder will not operate
correctly without the teon pads properly in place.
BATTERIES
The ProSensor T13 uses 2 AA batteries.
Replace both batteries at the same time.
REPLACING THE BATTERIES
• Remove the battery
cover by sliding the
cover to the left and
lifting. Remove both
batteries and dispose
of them properly.
Please recycle.
• Replace with two fresh AA batteries.
Replace both batteries at the same time.
• Close the battery cover by inserting the front clip into
the front battery cavity, gently depress the back of the
battery cover until it clicks closed.
STORAGE
Store the stud nder in a clean, dry place at room
temperature. Protect against direct sunlight and
moisture.
DISPOSAL
Stud nders and packaging should be sorted for
recycling.

No LED lights come on. Weak battery. Remove both batteries and replace with two fresh AA batteries.
Stud nder only works momentarily. The “on” button isn’t being held down.
The LED lights are indicating the location of
pipes and wires, not just studs.
Diculty starting a scan near doors and
8
windows.
Stud nder doesn’t work through new wall
paper.
My house was built prior to about 1960. The
walls are lath and plaster. The stud nder doesn’t
work very well anywhere in my house.
Inconsistent readings. Operator is holding the unit near the base rather than on the handle.
The LED lights sometimes seem to light up
sporadically or inconsistently.
The ProSensor T13 indicates the location of inconsistencies.
may indicate the location of a pipe, electrical wiring, other objects near the
surface being scanned, or an inconsistency in the surface material or paint,
etc.
Solid headers and triple studs are often present around doors and
windows. The ProSensor T13 indicates the change in density. If all eleven
sensors sense the same density, the LEDs will not illuminate.
The moisture in the wall after wall papering can block the stud nder’s
signal.
Older houses that were built with lath and plaster, instead of sheet rock,
often have too much inconsistency in the walls for the detector to work
reliably.
Anomaly in the surface material.
Sometimes after continuously scanning the wall for a period of time the
readings seem to be less consistent.
Wires, pipes, or other construction inconsistencies can cause erratic or
erroneous readings. Features on the opposite side of a wall may also be a
source of inconsistent readings.
The LED lights
Replace both batteries at the same time.
Hold the “on” button down until you have completed your scan.
Look for evenly placed studs on either side (16”, 24”, on center, etc.)
Scan above the location and below the location to conrm results.
Use caution before penetrating wall. See the SAFETY RULES FOR
THE PROSENSOR T13.
Begin the scan away from the window or door, then move the stud
nder to the area around the window or door. For best results, keep
stud nder 3” away from wood trim, outlets, switches, etc.
Wait until the wallpaper is dry. It may take up to 2 weeks for the
paper to dry suciently.
Try using the stud nder at a higher point on the wall, or a lower
point on the wall.
Only hold the unit by the handle with a nger continually pressing
the button.
Test at a higher or lower location on the wall.
Release the button and press the button again.
Test at points on the wall that are higher, or lower. The stud nder
may also work best if it is used more than 3 inches away from
metal objects such as outlets, light switches, etc.
