Digital Laser Detector (Fig.
H
–
K
)
Some laser kits include a
DeWALT
Digital Laser Detector. The
DeWALT
Digital Laser Detector allows you to locate a laser
beam emitted by a rotary laser in bright light conditions or over
long distances. The detector can be used in both indoor and
outdoor situations where it is difficult to see the laser beam.
The detector is not for use with non-rotating lasers but is
compatible with most rotary red-beam (DW0743R) and green
beam (DW0743G) lasers. It can be set to indicate the location
of the beam to either the nearest 1/8" (3 mm) or the nearest
1/25" (1 mm). The detector gives both visual signals through
the display window
22
and audio signals through the speaker
23
to indicate the location of the laser beam.
The
De
WALT Digital Laser Detector can be used with or without
the detector clamp. When used with the clamp, the detector can
be positioned on a grade rod, leveling pole, stud or post.
Installing a Battery in the Detector (Fig.
H
)
The Digital Laser Detector is powered by a 9 volt battery. To
install the battery provided, lift up on the battery compartment
cover
21
. Place the 9 volt battery in the compartment, aligning
the battery as shown.
Detector Controls (Fig.
I
)
The detector is controlled by the power button
26
and the
accuracy mode button
27
.
When the power button is pushed once, the detector is turned
on. The top of the display window shows the accuracy icon
27
, and the volume icon
28
. To decrease the volume of the
audible signal that the detector emits when it senses a laser
beam, push the button again; one of the half circles next to the
horn icon will dissappear. To turn off the audible signal push the
button a third time; the volume icon will dissapear. The
DeWALT
Digital Laser Detector also has an auto shut-off feature. If a
rotary laser beam does not strike the beam detection window,
or if no buttons are pressed, the detector will shut itself off in
about 30 minutes.
When the detector is on, the top of the window shows an
accuracy mode icon. Either the ±1/25" (1 mm) accuracy mode
icon
53
will appear, or the ±1/8" (3 mm) accuracy mode icon
54
will appear. When the ±1/25" (1 mm) accuracy mode icon
appears, it indicates that the detector will give an “on grade”
reading only when the laser beam is on grade or no more
than 1/25" (1 mm) above or below it. When the 1/8" (3 mm)
accuracy mode icon appears, it indicates that the detector will
give an “on grade” reading when the laser beam is on grade
or approximately 1/8" (3 mm) above or below it. Push the
accuracy mode button
27
once to change the accuracy mode.
Detector Operation (Fig.
I
,
J
)
1. Set up and position the rotary laser that you will be using
according to the manufacturer’s directions. Turn the laser
on and make sure that the laser is rotating and emitting a
laser beam. NOTE: This detector has been designed to be
used only with a rotating laser. The detector will not work
with a stationary beam laser level.
2. Turn the detector on by pressing the power/volume
button
26
.
3. Adjust the volume as desired as described in the
Detector Controls.
4. Position the detector so that the detector window
22
is
facing the laser beam produced by the rotary laser. Move
the detector up or down within the approximate area of the
beam, until you have centered the detector. For information
about the display window indicators and the audible signal
indicators, refer to the table titled Indicators (Fig.
J
).
5. Use the marking notches
30
to accurately mark the
position of the laser beam.
