6.2.6 Inspecting the Laser Plummet of the Instrument
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, return
the instrument to any GeoMax authorised service workshop.
Inspecting the laser
plummet step-by-step
The following table explains the most common settings.
6.2.7 Servicing the Tripod
Service the tripod step-
by-step
1) Tighten the leg cap screws moderately with the allen key supplied.
2) Tighten the articulated joints on the tripod head just enough to keep the tripod legs open when lifting
the tripod off the ground.
3) Tighten the screws of the tripod legs.
Step Description
1. Place and secure the instrument into the tribrach and onto a tripod.
2. Using the tribrach footscrews, level the instrument with the electronic level.
3. Access the electronic level and laser plummet by using the key-combination <FNC>+<.> or
by starting GeoMax Toolkit and go to MAIN MENU screen and select Level.
4. The laser plummet is switched on automatically when the Level up screen is entered. Adjust
the laser plummet intensity. Inspection of the laser plummet should be carried out on a bright,
smooth and horizontal surface, like a sheet of paper.
5. Mark the centre of the red dot on the ground.
6. 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.
7. 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 GeoMax 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.
