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 constructions.
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 measuring tool
to the height to be projected.
The laser target plate 29 has a reflecting coating which improves
the visibility of the laser beam from a larger distance or in case of
strong sun rays. The luminosity can be recognized only 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
receiver.

A relative millimeter 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 tri-
pod 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.
