Operating/Safety Instructions
FRANKLIN SENSORS PROSENSOR M90, M92 & M150
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 M90, M92 & M150
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. The stud finder is designed to detect any change in density but does not identify what type of 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.
WARNING: TURN OFF all gas, water, and electric power before using any drilling or penetrating the wall.
FAILURE TO TAKE THESE AND OTHER NECESSARY PRECAUTIONS COULD RESULT IN ELECTRIC SHOCK, FIRE, AND/OR SERIOUS INJURY AND DEATH.
OPERATING INSTRUCTIONS
TO OPERATE:
- Hold the stud finder by the handle. Do not touch the detector outside of the handle area while scanning.
- In certain models, 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 hasbeen 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.
LATH AND PLASTER
The ProSensor can see up to 1.5 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
Due to the variability in thickness and density in tile, roofing and exterior materials, detection is not guaranteed.
FIRE BLOCK OR HORIZONTAL STUDS
When searching for fire blocks or horizontal studs, turn the stud finder vertically and scan up and down the wall so the sensors can find the density differences in the wall.
BATTERIES
DO NOT USE RECHARGEABLE BATTERIES. The ProSensor uses 2 AAA batteries. Do not mix old and new batteries. Do not mix alkaline, standard or rechargeable batteries. Use 1.5 volt alkaline batteries only.
In select units, when the battery voltage is low, the second LED from the right will flash. Replace with 2 new batteries.
ProSensor M150
- LED Lights
- Detector Housing
- “On” Button
- Battery Cover
- Ergonomic Handle
- Sensor Board
- Live Electrical Warning™
REPLACING THE BATTERIES
Remove the battery cover:
- M150: by gently pushing on the right side and then lifting.
- M90 & M92: by gently depressing on each side and then lifting.
- Remove both batteries and dispose of them properly. Please recycle.
- Replace them with new AAA batteries.
- Close the battery cover by inserting the clip into the battery cavity. Gently push the other side of the battery cove,r inserting the other clip into the battery cavity until it clicks closed.
LIVE ELECTRICAL WARNING™ – M150 ONLY
The ProSensor M150 Live Electrical Warning™ works continually while the button is depressed. When a live electrical wire is detected, the yellow lightning bolt symbol may illuminate to indicate the presence of live wires. The ProSensor M150 uses Active Learning Technology™. When detecting live electrical wires, scan in both directions, passing over the same location multiple times, for a more accurate reading.
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.
STICKERS / DECALS
Do not place decals or stickers, especially those containing metal, onthe 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.
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.
ENVIRONMENTAL CONDITIONS
Franklin Sensors stud finders will work best when maintained in the following environmental conditions:
- Storage Temperature (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)
DISPOSAL
Stud finders and packaging should be sorted for recycling.
