Station Setup
If you choose to set up the total station over a marked point
from the plan (
Marked Points choice, diagram [1] below), you
will need to shoot one other point.
You may set up the total station on any location either on or
off a reference line (
Reference Line choice, see diagram [2]
below). This method can only be used with no plan entered.
If you choose to set up the total station at a random location
(
Any Location choice, diagram [3] below), you will need to
shoot at least two marked points from the plan for angle and
distance measurements, or at least three points if only angles
are to be measured. In either case, you can decide to shoot
more points for better control.
If you choose Use Last Setup, the total station will use the
coordinate system you determined when last setting it up (i.e.
according to one of the three methods described above).
The four possible station setup procedures are described
below.
1. Tap Instrument Setup from the Layout menu.
2. Choose how to set the instrument:
