Operating/Safety Instructions
FRANKLIN SENSORS PROSENSOR
Congratulations on selecting a Franklin Sensors stud finder – the most advanced wall sensing technology on the market. Your ProSensor incorporates advanced technology that precisely senses the surface in multiple locations simultaneously, then instantly identifies the location(s) of hidden object(s). It is quick, easy and accurate.
SAFETY RULES FOR THE PROSENSOR
WARNING: Read all instructions before use. Failure to follow safety instructions may result in electric shock, fire, 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 finder may also detect pipes, wires, or other objects that the user may not want it to detect. The stud finder 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 different features including, but not limited to, studs, beams, water pipes, gas pipes, wires, an inconsistency in the surface material or paint, etc.

OPERATING INSTRUCTIONS

TO OPERATE:

• Hold the stud finder by the handle. Do not touch the detector outside of the handle area while scanning.
• With the button held down, the LEDs will quickly flow to the center, indicating that the unit has power. You may immediately begin scanning the wall. You may press the button on or off the wall. No calibration is required. As you scan, LED lights will illuminate to display the location of any hidden object.
• LEDs track the center and edges of studs simultaneously. In certain models, the center LED will turn green once the precise center of the stud has been reached

HEAVY TEXTURE OR IRREGULARITIES:
Franklin Sensors stud finders identify the location of studs by identifying differences in the density of the material in the wall. Consequently areas of heavy texture and/or irregularities in the wall, can also cause the LEDs to illuminate. When this happens, you know your stud finder is doing its job. To help determine if you have actually found a stud, continue to press and hold the button and then scan the wall up and down. The LED lights will normally remain constant on a stud, whereas the LEDs will only display sporadically on a wall’s irregularity.
FINDING PIPES AND WIRES:
Franklin Sensors stud finders identify the location of studs by identify differences in the density of the material in the wall. Consequently wires or pipes that are near the surface, can also cause the LEDs to illuminate. When this happens, you know your stud finder is doing its job. To help determine if you have found a stud,  continue to press and hold the button and then scan the wall up and down. The LED lights will normally remain constant on a stud, whereas wires may only make contact in a small area and pipes may have elbows and branch off which may cause LEDs to only illuminate sporadically. ALWAYS TAKE THE NECESSARY SAFETY PRECAUTIONS AND TURN OFF all gas, water and electric power before penetrating the wall.No! RECHARGEABLE Batteries
BATTERIES
DO NOT USE RECHARGEABLE BATTERIES.
The ProSensor uses 2 AA batteries.
Do not mix old and new batteries.
Do not mix alkaline, standard or rechargeable batteries.
Use 1.5 volt alkaline batteries only.
REPLACING THE BATTERIES – T11 & T13/M132

• Remove the battery cover by sliding the cover to the right and lifting. Remove both batteries and dispose of them properly. Please recycle.
• Replace with new AA batteries.
• Replace battery cover. Close battery cover by sliding the cover to the left until it snaps into place.

REPLACING THE BATTERIES – 710 & 710+

• Remove battery cover, by sliding the cover to the left and lifting.
  Remove batteries and dispose of the batteries properly. Please recycle.
• Replace with new AA batteries.
• Replace battery cover. Close battery cover by sliding the cover to the right until it snaps into place.

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 not common, foil-backed insulation can cause inconsistent readings with all electronic stud finders, including the ProSensor.
Metallic Content in Wallpaper
Wallpaper with metallic content can block the detector’s signals.
Textured Walls and Acoustic Ceilings
The ProSensor is capable of detecting studs through many textures and surfaces. The unit will however work most accurately if placed firmly against the flattest portions of the wall. For the best results, prior to beginning your scan, identify a horizontal area that is consistently the flattest.
Lath and Plaster
The ProSensor T11, 710+, and 710 can see up to 1.6 inches, and the ProSensor T13 and M132 can see up to 1.7 inches, and thus can see through most lath and plaster walls. When irregularities in plaster thickness and variations in construction materials exceed this depth, detection is not guaranteed. Also, the stud finder may not be able to detect if the plaster uses metal mesh reinforcement.
Tile, Flooring, Roofing, and Exteriors
The ProSensor works by measuring the density of material behind the sensors to determine the location of studs. Due to the variability of density in tile flooring, roofing and exterior materials, we do not recommend the ProSensor 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 finder in any place.
DISASSEMBLY / TEFLON PADS
Do not disassemble the stud finder or remove the teflon pads on the bottom. The stud finder will not operate correctly without the teflon pads properly in place.
DISPOSAL
Stud finders and packaging should be sorted for recycling.
ENVIRONMENTAL CONDITIONS
Franklin Sensors stud finders will work best when maintained in the following environmental conditions:

Storage Temperatur	(0°F to 120°F) (-18°C to 50°C)
Storage Humidity	0% to 90% Relative humidity (non-condensing)
Operating Temperature	(32°F to110°F) (0°C to 43°C)
Operating Humidity	0% to 90% Relative humidity (non-condensing)

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 finder 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 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 finder is clean and dry. If necessary, wipe the stud finder dry using a clean cloth. If the detector is wet or dirty it may not operate properly.
Temperature
If the stud finder is subject to a significant temperature change, allow it to adjust to the ambient temperature before using. The entire area of the sensor board should be at a similar temperature for best operation.

TROUBLESHOOTING

CONDITION	PROBABLE CAUSE	SOLUTION
No LED lights come on.	Weak or Rechargeable Batteries.	DO NOT USE RECHARGEABLE BATTERIES. Replace with 2 new AA, 1.5-volt alkaline batteries. Do not mix old and new batteries.
Stud finder only works momentarily.	The “on” button isn’t being held down.	Hold the “on” button down until you have completed your scan.
Difficulty starting a scan near doors and windows.	Solid headers and triple studs are often present around doors and windows. The ProSensor indicates the change in density. If all the sensors sense the same density, the LEDs will not illuminate.	Begin the scan away from the window or door, then move the stud finder to the area around the window or door. For best results, keep stud finder 3″/7cm away from wood trim, outlets, switches, etc.
The LED lights sometimes seem to light up sporadically or inconsistently.	Operator is holding the unit near the base rather than on the handle.	Only hold the unit by the handle with a finger continually pressing the button.
Inconsistent readings.	Franklin Sensors stud finders find any change in density. The sensor’s job is to identify any changes in density. In the case of heavy texture, pipes and wires close to the surface of the wall, or other irregularities in the wall, the LEDs may illuminate. When this happens, you know your stud finder is doing its job!	When you get a reading, continue to press and hold the button and then scan the wall up and down. The LED lights will remain constant on a stud, while irregularities will only display temporarily.
