Inspecting the Laser Plummet of the Instrument

The laser plummet is located in the vertical axis of the instrument. Under nor-
mal conditions of use, the laser plummet does not need adjusting. If an adjust-
ment is necessary due to external influences, return the instrument to any
Leica Geosystems authorised service workshop.

The following table explains the most common settings.
1. Place and secure the instrument into the tribrach and onto a tripod.
2. Using the tribrach footscrews, level the instrument with the elec-
tronic level. In the Main Menu go to Status, Level and Laser
plummet, Level.
3. To enter the laser plummet page, press Page. Switch on the laser
plummet. Inspection of the laser plummet must be carried out on a
bright, smooth and horizontal surface, like a sheet of paper.
4. Mark the centre of the red dot on the ground.
5. Turn the instrument through 360° slowly, carefully observing the
movement of the red laser dot.
☞
The maximum diameter of the circular movement described by the
centre of the laser point must not exceed 3 mm at a distance of
1.5 m.
6. If the centre of the laser dot describes a perceptible circular move-
ment or moves more than 3 mm away from the point which was first
marked, an adjustment might be required. Inform your nearest Leica
Geosystems authorised service workshop. Depending on brightness
and surface, the diameter of the laser dot can vary. At 1.5 m it is
about 2.5 mm.
