Instrument Setup
Description
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 instru-
ment. 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.
