Working with the Laser Receiver (Accessory)
Under unfavourable light conditions (bright environment, direct
sunlight) and for larger distances, use the laser receiver for im-
proved finding of the laser beam 23.
RL25HV: When working with the laser receiver, select rotation-
al operation with the highest rotational speed.
Before working with the laser receiver, read and observe the la-
ser receiver operating instructions.
Working with the Remote Control (Accessory)
While pressing the operator buttons, the measuring tool can be
brought out of alignment so that the rotation is briefly stopped.
This effect is avoided when using the remote control 26.
The reception lenses 1 for the remote control are located on
four sides next to the rotation head.
Before working with the remote control, read and observe the
remote control operating instructions.
Working with the Tripod (Accessory)
The measuring tool is equipped with a 5/8" tripod mount for
horizontal operation on a tripod. Place the measuring tool via
the tripod mount 20 onto the 5/8" male thread of the tripod and
screw the locking screw of the tripod tight.
On a tripod 25 with a measuring scale on the elevator column,
the height difference can be adjusted directly.
Working with Wall Mount/Alignment Unit (Accessory)
(RL25HV)
– You can also mount the measuring tool to the wall mount with
alignment unit 28. For this, screw the 5/8" screw of the wall
mount into the tripod mount 20 of the measuring tool.
Mounting to a wall: Mounting to a wall is recommended, e.g., for
work above the elevation height of tripods or for work on unsta-
ble surfaces and without tripod. For this, fasten the wall mount
28, with the measuring tool mounted, as vertical as possible to
a wall.
Mounting on a tripod: The wall mount 28 can also be screwed
onto a tripod with the tripod mount on the back side. This meth-
od of fastening is especially recommended for work where the
rotational plane is to be aligned with a reference line.
With the alignment unit, the mounted measuring tool can be
moved vertically (when mounted to the wall) or horizontally
(when mounted to a tripod) within a range of approx. 15 cm.
Working with the Laser Target Plate (Accessory)
With the laser target plate 29, the laser mark can be projected
on the ground/floor or against a wall. With the magnetic holder,
the laser target plate can also be fastened to ceiling construc-
tions.
With the zero field and the scale, the offset or drop to the re-
quired height can be measured and projected at another loca-
tion. This eliminates the necessity of precisely adjusting the
measuring tool to the height to be projected.
The laser target plate 29 has a reflecting coating which im-
proves the visibility of the laser beam from a larger distance or
in case of strong sun rays. The luminosity can be recognized on-
ly if you look to the laser target plate in parallel to the laser
beam.

Working with the Measuring Rod (Accessory)
For checking irregularities or projecting gradients, it is recom-
mended to use the measuring rod 24 together with the laser re-
ceiver.
A relative millimetre scale (±50 cm) is marked on the top of the
measuring rod 24. Its zero height can be preset at the bottom of
the elevator column. This allows for direct reading of deviations
from the specified height.

Work Examples

Checking the Depth of Building Pits (see figure B)
– Position the measuring tool on a firm surface or mount it to a
tripod 25.
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 be-
tween the laser beam and the height at the reference point
with the laser target plate 29. Project or check the measured
height difference at the target location.
When measuring over long distances, the measuring tool should
always be set up in the centre of the work surface and on a tri-
pod, in order to reduce interferences.
When working on unsafe ground, mount the measuring tool on-
to the tripod 25. Take care that the shock-warning function is
activated, in order to avoid faulty measurements in case of
ground vibrations or shock to the measuring tool.
