Laser plummet
The laser plummet is located in the
vertical axis of the instrument.
Under normal conditions of use the
laser plummet does not need
adjusting. If an adjustment is
necessary due to external influences
the instrument has to be returned to
any Leica Geosystems service
department.
Inspecting by turning the plummet
360°:
1. Place the instrument on the tripod
and level it up.
2. Switch on the laser plummet and
mark the centre of the red dot.
3. Slowly turn the instrument through
360°, carefully observing the
movement of the red laser dot.
Inspection of the laser plummet
should be carried out on a bright,
smooth and horizonal surface (e.g. a
sheet of paper).
Laser dot:
Diam. 2.5 mm /
1.5 m
If the centre of the laser dot
describes a perceptible circular
movement or moves more than 3 mm
away from the point which was first
marked, an adjustment may be
required. Inform your nearest Leica
Geosystems service workshop. Depending on brightness and
surface, the diameter of the laser dot
can vary. At a distance of 1.5 m it will
be about 2.5mm.
The maximum diameter of the
circular movement described by the
centre of the laser point should not
exceed 3 mm at a distance of 1.5m.
