Automatic mode with subsequent readjustment
In many operating conditions (e.g. on strongly vibrating surfaces), it is useful for
the rotation laser to level itself constantly to eliminate any discrepancies that may
arise. After switching it on with button (3), the unit can be switched to this mode by
pressing button (4). The red LED (4) indicates that this mode is active.
Minor discrepancies from the horizontal (from minor tremors) are compensated for.
If these disruptive influences are too great, rotation stops, the laser beam switches
off and the laser unit levels itself again automatically. Once re-levelling is comple-
te, the splitter Pentaprism starts to rotate again.
Height of tool alert function
Minor tremors or vibrations are automatically compensated for only up to a set
threshold. If these disruptive influences are greater than this, the height of tool
alert function engages and rotation stops. The laser beam switches off and the
LED (4) flashes. You must switch the laser unit off using button (3) and then switch it
on again.
Disruptive influences that can lead to adjustment of the precise alignment and the
laser beam's setting do not therefore go unnoticed. When there are disruptive
influences present, the height of tool alert function requires the laser to be checked
and/or reset to the desired position.
Use as a Plumb-line Laser
The laser can be aligned precisely on a marked cross
using the 4 markings (9) on the base to transfer a
plumbline from the floor marking to the ceiling. The
point where the cross intersects corresponds to the
SP1 vertical laser emitter.
A correct result can only be obtained in Automatic
mode with the unit set on a level surface!
The LAR-200 rotation laser has been designed for building site use and leaves our
factory perfectly calibrated. As with any precision instrument, however, its calibra-
tion must be regularly checked. The unit should be checked before starting any
new tasks, particularly when the unit has been exposed to strong vibrations. After
an impact, the unit should be checked throughout its whole self-levelling range.
