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
C
).
2.
Position the stud sensor flat against the wall and parallel
to a door or window on the same wall, which give you an
indication of how the studs are positioned behind the wall.
3.
Without moving the stud sensor, use your pointer finger to
press and hold
until all the LEDs (except the green Power
LED) turn off (1 sec).
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.
• If lights (Figure A 7 ), move the stud sensor to the
left to find the nearest stud.
• If lights (Figure A 4 ), move the stud sensor to the
right to find the nearest stud.
6.
When the center LED (Figure
A 5
) lights and you hear a
constant beep, the stud sensor has found the center of a
stud (Figure
D 1 ).
• STOP moving the stud sensor.
• STOP pressing
(Figure D 2 ).
7.
Through the hole on the stud sensor (Figure D 3 ), use a
pencil to mark the current position as the center of the stud.
8.
To find another stud on the wall, repeat the same steps.
Finding Live AC
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
C
).
2.
Gently place the stud sensor flat against the wall and
parallel to a door or window on the same wall, which give
you an indication of how the studs are positioned behind the
wall.
3.
Without moving the stud sensor, press and hold until all
the LEDs (except the green Power LED) turn off (1 sec).
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 LEDs and listen for
beeps. The AC LED (Figure
A 3 ) will start illuminating and
the stud sensor will sound a cadenced beep from a typical
distance of 6”-18” (.15m - .5m) away from the live AC. Since
AC wires are usually attached to studs, the directional LEDs
will help you find live AC wires that may be attached to the
nearest stud.
• If lights (Figure A
7
), move the stud sensor to the
left to find the nearest stud.
• If lights (Figure A 4 ), move the stud sensor to the
right to find the nearest stud.
• If live AC voltage is found within 6”-18” (.15m - .5m) of
the stud sensor’s current position, the AC LED (Figure A
3
) will illuminate and you will hear a few short beeps.
• If live AC voltage is found near the center of a stud, both
the AC LED and the center red LED (Figure
A
5 ) will illuminate and the stud sensor will sound the
short alternating beeps (AC found) followed by a longer
constant beep (stud center found), and repeat these beeps
until you stop pressing
.
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).
