4.1 Instrument Setup
This topic describes an instrument setup over a marked ground point using the laser plummet. It
is always possible to set up the instrument without the need for a marked ground point.
Important features
•
It is always recommended to shield the instrument from direct sunlight and avoid uneven
temperatures around the instrument.
•
The laser plummet described in this topic is built into the vertical axis of the instrument. It
projects a red spot onto the ground, making it appreciably easier to centre the instrument.
•
The laser plummet cannot be used with a tribrach equipped with an optical plummet.
☞
When setting up the tripod
pay attention to ensuring a
horizontal position of the tri-
pod plate. Slight corrections of
inclination can be made with
the foot screws of the tribrach.
Larger corrections must be
done with the tripod legs.
