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
D
1
),
continue moving the stud sensor to the right to find the nearest stud.
As you get closer to the stud, will light (Figure
D
2
).
• 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
E
1
). To aid in locating the wire position, place
your other hand on the surface approximately 12” (30cm) from the
stud sensor (Figure
E
2
), 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
D
3
).
NOTE:
If live AC voltage is found near the center of a stud, both the AC
LED and the center LEDs 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
D
4
) 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.
Maintenance
• When the stud sensor is not in use, clean the exterior parts with a damp
cloth, wipe the stud sensor with a soft dry cloth to make sure it is dry.
• Although the stud sensor exterior is solvent resistant, NEVER use
solvents to clean the stud sensor.
• Store the stud sensor in a clean location at a temperature between -67 ˚F
(-55 ˚C) and 158 ˚F (70 ˚C).
Troubleshooting
The LED is Blinking
The battery power is low.
• Check the AAA batteries to make sure:
• Each battery is installed correctly, according to
+
and
–
listed inside
the battery compartment.
• The battery contacts are clean and free of rust or corrosion.
• The batteries are new, high-quality batteries to reduce the chance of
battery leakage.
• Make sure the AAA batteries are in proper working condition. If in doubt,
try installing new batteries.
The LED does not Turn On
If the power LED does not turn on, or the power LED turns on for 1
sec and then turns off, there is no battery power.
• Install two new, high-quality, name-brand AAA batteries in the stud sensor.
• Make sure each battery is installed correctly, according to
+
and
–
listed
inside the battery compartment.
The Stud Sensor is not Finding Studs
• Make sure the batteries are working.
• Make sure you have placed the stud sensor on a wall made of drywall or
another common building material. The stud sensor will not work on walls
made of concrete, mortar, block, brick work, plaster, carpeting, foil- faced
materials, metallic surfaces, or ceramic tile.
• Make sure you have placed the stud sensor flat against the wall, the stud
sensor is in a vertical position (parallel to a door or window), and you are
pressing and holding
(Figure
A
3
) as you move the stud sensor
SLOWLY
against the wall.
• Make sure the wall is not too thick. The DW0250 stud sensor can be used
to detect wood studs on walls < 1” (25mm) thick or metal studs on walls <
1.5” (38mm) thick.
• Make sure the wall has a smooth surface.
• Make sure the temperature is within the specified
Operating Range
and
Relative Humidity
.
