is not aligned to emit in a direction parallel with the measurement laser. Instead, its beam intersects with that
of the measurement laser at a distance of 75 m. The tolerance on pilot laser position in relation to the invisible
measurement laser as a function of the distance to a target being measured is shown in the following draw-
ing, see
Fig. 7 .

When aligning check as follows:
Move the sensor at a very short distance to the reflector (for example < 1 m). The light spot is located in
the lower left corner of the reflector.
Move the sensor with the longest range to the reflector. Check the position of the light spot at the reflec-
tor and set it if necessary.
