Stud Sensor Information
The Stud Sensor DW0250 uses electronic signals to locate the center of
wood or metal studs, or live AC wires through drywall or other common
building materials.
PLEASE NOTE:
• The stud sensor will not detect objects in concrete, mortar, block, brick
work, plaster, carpeting, foil-faced materials, metallic surfaces, or ceramic
tile.
• The stud sensor is not designed to locate non-ferrous or plastic objects,
such as pipes.
Once the center of a wood or metal stud has been detected in one pass
across the surface, the Stud Sensor DW0250 turns on the center LEDs and
sounds an audible tone. A marking hole allows you to easily note the current
position on the wall.

WARNING:
Read and understand all instructions. Failure to follow the
warnings and instructions in this manual may result in serious
personal injury.
SAVE THESE INSTRUCTIONS
WARNING:
The following label information can be found on your tool for your
safety.
WARNING:
If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may
be impaired.
CAUTION:
Protect your eyes. Wear safety goggles.
WARNING:
This tool is not a measuring device and should not be used as
a substitute for a voltmeter.
WARNING:
The LED or Live Wire Detection symbol on the display is just an
indicator and in some situations the voltage detection option may
not accurately indicate the presence of voltage in a wall in the
event of internal device failure or improper operation, and therefore
should not be solely relied upon for identification of the presence
of hazardous voltages. Other evidence, such as construction
blueprints or visual identification of wiring or conduit entry points
should also be utilized.
Always follow proper safety practices and use a separate detection
method to verify a de-energized condition prior to commencing
work.
WARNING:
Always turn off AC power when working near wiring.
WARNING:
Shielded wires or wires in metal conduits, casings, metalized
walls, or thick, dense walls may not be detected.
CAUTION:
Use personal protective equipment. Always wear eye protection.
Depending on the work conditions, wearing protective equipment
such as a dust mask, non-skid safety shoes, hard hat, and hearing
protection will reduce the risk of personal injury.
IMPORTANT SAFETY NOTICE
Ensure proper detection of live wires. Always hold the Stud Sensor
DW0250 in the handle area only. Grasp between fingers and thumb while
making contact with your palm (Figure
