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.
