Working with the Measuring Rod (Accessory)
(see figure H)
For checking irregularities or projecting gradi-
ents, it is recommended to use the measuring
rod
27
together with the laser receiver.
A relative millimeter scale (
±
50 cm) is marked
on the top of the measuring rod
27
. Its zero
height can be preset at the bottom of the eleva-
tor column. This allows for direct reading of de-
viations from the specified height.
Work Examples
Projecting/Checking Heights (see figure B)
Position the measuring tool in the horizontal po-
sition onto a firm support or mount it onto a tri-
pod
26
(accessory).
Working with tripod: Align the laser beam to the
requested height. Project or check the height at
the target location.
Working without tripod: Determine the height
difference between the laser beam and the
height at the reference point with help of the
measurment plate
34
. Project or check the meas-
ured height difference at the target location.
Parallel Alignment of a Plumb Beam/Project-
ing Right Angles (see figure C)
When right angles are to be projected or when
partitions are to be aligned, the plumb beam
9
must be aligned parallel, meaning at the same
distance to a reference line (e.g. a wall).
For this, set up the measuring tool in the vertical
position and position it in such a manner that
the plumb beam runs approximately parallel to
the reference line.
For exact positioning, measure the clearance
between plumb beam and reference line direct-
ly on the measuring tool with help of the meas-
urment plate
34
. Measure the clearance be-
tween plumb beam and reference line again as
far away as possible from the measuring tool.
Align the plumb beam in such a manner that it
has the same clearance to the reference line as
when measured directly at the measuring tool.
The right angle to the plumb beam
9
is indicated
by the variable laser beam
6
.
Indicating a Plumb Line/Vertical Plane
(see figure D)
To indicate a plumb line or a vertical plane, set
up the measuring tool in the vertical position.
When the vertical plane is supposed to run at a
right angle to a reference line (e.g. a wall), then
align the plumb beam
9
with this reference line.
The plumb line is indicated by the variable laser
beam
6
.
Working without Laser Receiver (see figure E)
Under favourable light conditions (dark environ-
ment) and for short distances, it is possible to
work without the laser receiver. For better visi-
bility of the laser beam, either select line opera-
tion, or select point operation and manually ro-
tate the rotation head
10
to the target location.
Working with the Laser Receiver (see figure F)
Under unfavourable light conditions (bright en-
vironment, direct sunlight) and for larger dis-
tances, use the laser receiver for improved find-
ing of the laser beam. When working with the
laser receiver, select rotational operation with
the highest rotational speed.
