Accuracy Check and
Calibration
Checking Accuracy –
Horizontal Beam, Scan Direction (See figure
6
Checking the horizontal scan calibration of the laser requires
two walls 30' (9 m) apart. It is important to conduct a calibration
check using a distance no shorter than the distance of the
applications for which the tool will be used.
1. Attach the laser to a wall using its pivot bracket. Make sure
the laser is facing straight ahead.
2. Turn on the laser's horizontal beam and pivot the laser
approximately 45˚ so that the right-most end of the laser
line is striking the opposing wall at a distance of at least 30'
a
(9 m). Mark the center of the beam .
3. Pivot the laser approximately 30˚ to bring the left-most end
of the laser line around to the mark made in Step 2. Mark
b
the center of the beam .
4. Measure the vertical distance between the marks.
5. If the measurement is greater than the values shown below,
the laser must be serviced at an authorized service center.
Distance Between Walls Allowable Distance
Between Marks
9 m (30') 3.0 mm (1/8")
12 m (40') 4.0 mm (5/32")
15 m (50') 5.0 mm (7/32")
Checking Accuracy –
Horizontal Beam, Pitch Direction (See figure
7
Checking the horizontal pitch calibration of the laser requires
a single wall at least 30' (9 m) long. It is important to conduct
a calibration check using a distance no shorter than the distance
of the applications for which the tool will be used.
1. Attach the laser to one end of a wall using its pivot bracket.
2. Turn on the laser's horizontal beam and pivot the laser
toward the opposite end of the wall and approximately
parallel to the adjacent wall.

3. Mark the center of the beam at two locations
30' (9 m) apart.
4. Reposition the laser to the opposite end of the wall.
5. Turn on the laser's horizontal beam and pivot the laser back
toward the first end of the wall and approximately parallel to
the adjacent wall.
6. Adjust the height of the laser so that the center of the beam

is aligned with the nearest mark .

Checking Accuracy –
Vertical Beam (See Figure )
8
Checking the vertical (plumb) calibration of the laser can be
most accurately done when there is a substantial amount of
vertical height available, ideally 30' (9 m), with one person on
the floor positioning the laser and another person near a ceiling
to mark the position of the beam. It is important to conduct
a calibration check using a distance no shorter than the distance
of the applications for which the tool will be used.
1. Start by marking a 5' (1.5 m) line on the floor.
2. Turn on the laser's vertical beam and position the unit at
one end of the line, facing the line.
3. Adjust the unit so its beam is aligned and centered on the
line on the floor.
4. Mark the position of the laser beam on the ceiling
the center of the laser beam directly over the midpoint of the
line on the floor.
5. Reposition the laser at the other end of the line on the
floor. Adjust the unit once again so its beam is aligned and
centered on the line on the floor.
6. Mark the position of the laser beam on the ceiling
f
directly beside the first mark .
7. Measure the distance between these two marks.

Troubleshooting

The Laser Does Not Turn On
• Make sure AA batteries (when used) are installed correctly
according to (+) and (–) on the inside of the battery door.
• Make sure the batteries or rechargeable pack are in proper
working condition. If in doubt, try installing new batteries.
• Make sure that the battery contacts are clean and free of
rust or corrosion. Be sure to keep the laser level dry and use
only new, high-quality, name brand batteries to reduce the
chance of battery leakage.

, .
• If the laser unit is heated above 50 ˚C (120 ˚F), the unit will
not turn on. If the laser has been stored in extremely hot
temperatures, allow it to cool. The laser level will not be
damaged by pressing the on/off button before cooling to its
proper operating temperature.
The Laser Beams Flash
The DCE088R and DCE088G have been designed to self-
level up to an average of 4° in all directions when positioned
as shown in 3
mechanism cannot level itself, the laser beam will flash
indicating that the tilt range has been exceeded. The flashing
beams created by the laser are not level or plumb and
should not be used for determining or marking level or
plumb. Try repositioning the laser on a more level surface.
The Laser Beams Will Not Stop Moving
The DCE088R and DCE088G are precision instruments.

. Mark
Therefore, if the laser is not positioned on a stable (and
motionless) surface, the laser will continue to try to find level. If
the beam will not stop moving, try placing the laser on a more
stable surface. Also, try to make sure that the surface is
relatively flat, so that the laser is stable.
