the door opening (point II) and at the upper
edge of the door opening (point III).
– Position the tool on the other side of the
door opening directly behind point II. Allow
the tool to level in and align the vertical
laser line in such a manner that its center
runs exactly through points I and II.
– The difference d between point III and the
center of the laser line at the upper edge of
the door opening results in the actual
deviation of the tool from the vertical plane.
Attaching with the Magnetic Bracket
To fasten the tool on the magnetic bracket 9,
screw the locking screw 10 of the magnetic
bracket into the 1/4" tripod mount 2 on the
tool and tighten. To rotate the measuring tool
on the magnetic bracket, slightly loosen the
screw 10.
With the magnetic bracket 9, the tool can be
attached as follows:
– Mount the magnetic bracket 9 to the tripod
19 or a commercially available camera
tripod via the 1/4" tripod mount 14. For
fastening to a commercially available
construction tripod, use the 5/8" tripod
mount 15.
– The magnetic bracket 9 can be fastened to
steel parts via the magnets 13.
– The magnetic bracket 9 can be fastened to
drywalls or wood walls with screws. For
this, insert screws with a minimum length of
2" into the screw holes 11 of the magnetic
bracket.
– The magnetic bracket 9 can also be
fastened to pipes or similar beams using a
commercially available strap by threading it

attachment.
Working with the Measuring Plate (Accessory) (see
figures A - B)
With the laser target plate 18, it is possible
to project the laser mark onto the floor or the
laser height onto a wall.
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 laser target plate 18 has a reflective
coating that enhances the visibility of the laser
– Measure the height of the door opening.
The maximum permitted deviation dmax is
calculated as follows:
dmax = double height of the door opening
x 0.0036 in/ft
Example: With a door opening height of 2
meters, the maximum permitted deviation
is dmax = 2 x 7 ft x 0.0036 in/ft = 0.05 in.
Thus, the marks must not be more than
0.05 in. apart.
Working Advice
Use with Attachments
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.
Working with a Tripod (Accessory)
A tripod offers a stable, height-adjustable
measuring support. Place the tool via the
tripod mount 2 onto the 1/4" male thread of
the tripod and screw the locking screw of the
tripod tight.
Laser Viewing Glasses (Accessory)
The laser viewing glasses 17, 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
are used for improved visualization of the
laser beam, but they do not protect against
laser radiation.
• 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 colour perception.
