Installation and mounting
Aligning the laser light spot in the center of the reflector
The laser light spot has to be aligned so that it always hits the center of the opposing
reflector, both at close range as well as at the maximum measurement distance. To align,
use the two M 5 Allen screws ("A" in figure 5.2). When aligning please ensure that the
knurled nut and the lock nut ("B" in figure 5.2) are opened wide.
Attention!
To prevent the laser measurement system from moving out of alignment during continuous
operation, subsequently hand-tighten the knurled nut and counterlock with the WAF 4 nut
("B" in figure 5.2). Knurled nut and nut must not be tightened until alignment has been
completed.
Attention!
The device must not be opened. Failure to comply will render the guarantee void. Warranted
features cannot be guaranteed after the device has been opened.
