Stud Sensor Information
The Stud Sensor DW0300 uses electronic signals to locate the center of
wood or metal studs, live AC wires, or metal objects (e.g., pipe) 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 will not detect plastic or PVC pipes.
Once the center of a wood or metal stud, or a metal object has been
detected in one pass across the surface, the Stud Sensor DW0300 turns on
the center LEDs and sounds an audible tone. A marking hole allows you to
easily note the current position on the wall.

from the stud sensor.
3. Insert two new, high-quality AAA batteries, making sure to position the
-and +ends of each battery as noted inside the battery compartment
(Figure B3).
4. Place the cover back on the stud sensor (Figure B4).
• Insert the two pins at the top of the cover into the holes near the top of
the battery compartment.
• Slowly lower the cover and press down until the latch locks securely
on the stud sensor.
5. Press or to test the stud sensor.
• The stud sensor should sound one short beep. The Power LED
should turn on. All the other LEDs should illuminate for a second and
then turn off.
• Whenever you press or , the green Power LED should
illuminate to indicate that the batteries are good. If this LED blinks or
does not illuminate, change the batteries.
Using the Stud Sensor
The DW0300 stud sensor will help you nd wood or metal studs, AC
voltage, or metal objects (e.g., pipe) behind drywall.
• The stud sensor has two buttons. Use the bottom button (Figure A3) to
search for wood/metal studs or AC, and use the top button (Figure A2)
to search for metal objects (e.g., pipe).
• The stud sensor will detect wood studs through up to 1” (25mm) thick
drywall, and metal studs and AC voltage through up to 1.5” (38mm) thick
drywall.
• The stud sensor will detect a ferrous metal object (contains iron) up to 3”
(76.2mm) from the surface of the wall to the center of the object.
• The stud sensor will detect a non-ferrous metal object (e.g., copper) up to
2” (51mm) from the surface of the wall to the center of the object.
• When AC voltage is found, the stud sensor will sound short (alternating)
beeps and light the AC LED (Figure A5).
• When the center of a stud is found (or a metal object is nearby), the stud
sensor will sound one longer (constant) beep and light the center LEDs
(Figure A4).
• When live AC and the center of a stud are both found, the stud sensor will
alternate between the long and short beeps, and light the center LEDs
and the AC LED.
Finding a Stud
1. To hold the stud sensor, place your thumb on one side of the stud
sensor, your pointer finger and your palm over the center of the stud
sensor, and the rest of your fingers on the same hand on the other side
of the stud sensor (Figure C1).
2. Gently place the stud sensor flat against the wall and parallel to a door
or window on the same wall, which gives you an indication of how the
studs are positioned behind the wall (Figure C2).

3. Without moving the stud sensor, use your pointer finger to press and
hold (Figure A3). WAIT 1 sec until all the LEDs (except the
Power LED) turn off.
4. While still pressing , SLOWLY move the stud sensor to the left or
the right on the wall.
5. As you move the stud sensor, watch the stud sensor LEDs and listen
for beeps.
• If lights on the right side of the stud sensor (Figure D1),
continue moving the stud sensor to the right to find the nearest stud.
As you get closer to the stud, will light (Figure D2).
• If lights on the left side of the stud sensor, continue moving the
stud sensor to the left to find the nearest stud. As you get closer to the
stud, will light.
• If live AC voltage is found within 6”-18” (.15m - .5m) of the stud
sensor’s current position, the AC LED will illuminate and you will hear
short beeps.
NOTE: Static electrical charges that can develop on drywall and
other surfaces will spread the voltage detection area many inches on
each side of the actual electrical wire. This can cause the stud sensor
to indicate that it has found live AC when it is not actually near an
electrical wire (Figure E1). To aid in locating the wire position, place
your other hand on the surface approximately 12” (30cm) from the
stud sensor (Figure E2), or hold the stud sensor ½” - 2” (13mm -
50mm) away from the wall surface.
6. When the center LEDs light and you hear a constant beep, the stud
sensor has found the center of a stud (Figure D3).
NOTE: If live AC voltage is found near the center of a stud, both the
AC LED and the center LEDs (Figure A4) will illuminate and the stud
sensor will sound the short alternating beeps (AC found) followed by a
longer constant beep (stud center found).
• STOP moving the stud sensor and continue to hold it at the current
position.
• STOP pressing .
7. Through the hole on the stud sensor (Figure D4) use a pencil to
mark the current position on the wall as the center of the stud.
8. To find another stud on the wall, repeat the same steps.
Finding Metal Objects
The stud sensor will let you know if a metal object (e.g., a pipe) is located
behind the wall within 3” (76.2mm) of the stud sensor. In metal detection
mode, the arrows do not indicate which direction to move the stud
sensor to nd metal.
1. To hold the stud sensor, place your thumb on one side of the stud
sensor, your pointer finger and your palm over the center of the stud
sensor, and the rest of your fingers on the same hand on the other side
of the stud sensor (Figure C1).
2. Position the stud sensor flat against the wall and parallel to a door or
window on the same wall, which gives you an indication of how the
studs are positioned behind the wall (Figure C2).
3. Without moving the stud sensor, use your pointer finger to press and
hold (Figure A2). After 1 sec all the LEDs (except the Power
LED) will turn off.
4. While still pressing , SLOWLY move the stud sensor to the left or
the right on the wall.
5. As you move the stud sensor, watch the stud sensor LEDs.
• When and light on the left and right sides of the stud sensor,
slowly move the stud sensor to the left or right to find the metal object
(Figure F1).
• When and light on the left and right sides of the stud sensor,
you will know that you are moving the stud sensor closer to the metal
object (Figure F2).
6. When the center LEDs (Figure A4) light and you hear a constant
beep, the stud sensor has found a metal object (Figure F3).
• STOP moving the stud sensor and continue to hold it at the current
position.
• STOP pressing .
7. Through the hole on the stud sensor (Figure F4) use a pencil to
mark the current position on the wall.
