3. Using the footscrews of the
tribrach, centre the plummet to the
ground point.
4. Move the legs of the tripod to
centre the bull’s-eye bubble.
The laser plummet cannot be
used in conjunction with a
tribrach which already has an
optical plummet.
5. Level-up precisely, using the
electronic bubble (see the chapter
"Levelling-up with the electronic
bubble").
6. Centre precisely by shifting the
tribrach on the tripod plate.
Repeat steps 5 and 6 until the
required accuracy is reached.
1. Target the ground point or activate
the laser plummet.
2. Set up the GST20, centring it as
well as possible.
The laser plummet is built into the
vertical axis of the TPS1100
instruments. Projecting a red dot on
to the ground makes it appreciably
easier to centre the instrument.
