– Mark the center of the laser line at the
upper edge of the door opening as point IV.
– The difference d of both marked points III
and IV results in the actual deviation of the
tool to the plumb line.
– Measure the height of the door opening.
The maximum admissible deviation is
calculated as follows:
Repeat the measuring procedure for the
second vertical laser plane. For this, select
an operating mode in which a vertical laser

plate
The laser target plate 15 increases the
visibility of the laser beam under unfavourable
conditions and at large distances.
The reflective part of the laser target plate
15 improves the visibility of the laser line.
Thanks to the transparent part, the laser line
is also visible from the back side of the laser
target plate.
Working with the Tripod (Optional
Accessory)
A tripod offers a stable, height-adjustable
measuring support. Position thetool with the
1/4-20 tripod mount 10 onto the thread of the
tripod 23 or a commercially available camera
tripod. For fastening to a commercially
available construction tripod, use the 5/8-11
tripod mount 9. Tighten the tool with the tripod
mounting stud.
Fastening with the BM 1
Positioning Device (Accessory)
(see figure D)
With the BM 1 positioning device 19, you can
fasten the tool, e.g., to vertical surfaces, pipes
or magnetic materials. The BM 1 positioning
device is also suitable for use as a ground
tripod and makes the height adjustment of the
tool easier. The clip attachment is suitable for
drop ceiling applications.
Working with the Measuring Plate
(Optional Accessory)
(See figures A-B)
With the measuring plate 16, it is possible to
project the laser mark onto the floor or the
laser height onto a wall.

plane is generated aside of the tool. Turn the
tool 90° before beginning with the measuring
procedure.
Doubled height of the door opening x 0.0024
in/ft
Example: For a door-opening height of 6.5ft,
the maximum deviation may be
2 x 6.5 ft x ±0.0024 in/ft = ±1/32 (0.312
in) Consequently, points III and IV may be
no more than 1/32 in (max.) apart from
each other.
Use with Attachments
With the zero field and the scale, the offset or
drop to the required height can be measured
and projected at another location. This
eliminates the necessity of precisely adjusting
the tool to the height to be projected.
The measuring plate 16 has a reflective
coating that enhances the visibility of the
laser beam at greater distances or in intense
sunlight. The brightness intensification can be
seen only when viewing, parallel to the laser
beam, onto the measuring plate.
Under unfavourable light conditions (bright
environment, direct sunlight) and for larger
distances, use the laser receiver for improved
finding of the laser lines 17. When working
with the laser receiver, switch the pulse
function on (see "Pulse Function").
The laser viewing glasses filter out the
ambient light. This makes the red light of the
laser appear brighter for the eyes.
• Do not use the laser viewing glasses as
safety goggles. The laser viewing glasses
• Do not use the laser viewing glasses as
sun glasses or in traffic. The laser

viewing glasses do not afford complete UV
protection and reduce color perception.
