– Mark the centre of the vertical laser line on the floor of the
door opening (point
Ⅰ
), 5 m away on the other side of the
door opening (point
Ⅱ
) and on the upper edge of the door
opening (point
Ⅲ
).

– Rotate the measuring tool 180° and position it on the
other side of the door opening, directly behind point
Ⅱ
.
Allow the measuring tool to level in and align the vertical
laser line in such a way that its centre passes through
points
Ⅰ
and
Ⅱ
exactly.
– Mark the centre of the laser line on the upper edge of the
door opening as point
Ⅳ
.
– The discrepancy
d
between the two marked points
Ⅲ
and
Ⅳ
reveals the actual vertical deviation of the measuring
tool.
– Measure the height of the door opening.
Repeat the measuring process for the two vertical laser
planes. To do this, select the operating mode for generating
a vertical laser plane to one side of the measuring tool and
rotate the measuring tool by 90° before beginning the meas-
uring process.
You can calculate the maximum permitted deviation as fol-
lows:
Doubled height of the door opening ×
0.3
mm/m
Example: At a door opening height of
2
m, the maximum de-
viation amounts to
2 ×
2
m × ±
0.3
mm/m = ±
1.2
mm. The points
Ⅲ
and
Ⅳ
must therefore be no further than
1.2
mm from each other.
Working Advice
u
Only the centre of the laser line must be used for
marking.
The width of the laser line changes depending
on the distance.
Working with the Laser Target Plate
The laser target plate
(16)
improves visibility of the laser
beam in unfavourable conditions and at greater distances.
The reflective half of the laser target plate
(16)
improves vis-
ibility of the laser line. The transparent half enables the laser
line to be seen from behind the laser target plate.
Working with the Tripod (Accessory)
A tripod offers a stable, height-adjustable support surface
for measuring. Place the measuring tool with the 1/4" tripod
mount
(8)
on the thread of the tripod
(20)
or a conventional
camera tripod. Use the 5/8" tripod mount
(9)
to secure the
measuring tool on a conventional building tripod. Tighten the
measuring tool using the locking screw of the tripod.
Roughly align the tripod before switching on the measuring
tool.
Securing with the universal holder (accessory)
(see figure B)
Using the universal holder
(15)
, you can secure the measur-
ing tool on vertical surfaces, pipes or magnetizable materi-
als, for example. The universal holder is also suitable for use
as a building tripod and facilitates height adjustment of the
measuring tool.
Roughly align the universal holder
(15)
before switching on
the measuring tool.
Working with the laser receiver (accessory)
(see figure B)
Use the laser receiver
(17)
to improve detection of the laser
lines in adverse lighting conditions (bright environment, dir-
ect sunlight) and over greater distances. When working with
the laser receiver, switch on receiver mode (see "Receiver
Mode", page 8).
Laser Goggles (Accessory)
The laser goggles filter out ambient light. This makes the
light of the laser appear brighter to the eye.
u
Do not use the laser goggles as protective goggles.
The laser goggles make the laser beam easier to see; they
do not protect you against laser radiation.
u
Do not use the laser goggles as sunglasses or while
driving.
The laser goggles do not provide full UV protec-
tion and impair your ability to see colours.
Example applications (see figures A–F)
Examples of possible applications for the measuring tool can
be found on the graphics pages.
Maintenance and Service
Maintenance and Cleaning
Keep the measuring tool clean at all times.
Never immerse the measuring tool in water or other liquids.
