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 in conjunction with a tribrach equipped with
an optical plummet.

When setting up the tripod pay attention
to ensuring a horizontal position of the
tripod plate. Slight corrections of inclina-
tion can be made with the foot screws of
the tribrach. Larger corrections must be
done with the tripod legs.
