10 Measuring with a Total Station
Setting up on a known point
This enables you to set up the total station over a known control point location and then measure
to one or more reference control points to establish its position and orientation on the jobsite. In
most cases, a single reference control point may be all that is required. In other cases, where the
accuracy of the work is higher, measuring more than one reference control point can provide better
control over the orientation of the total station and a further check that the control point at the
total station position or any of the measured reference control point locations has not moved.
Unlike the arbitrary location method, once you measure a single reference control point, the
information shown below appears on the screen. You can follow similar steps to those used in the
arbitrary location method of station establishment. Select from one of the following options:
1.
From theTotal Station menu, tap . If you have just connected to the total station,
the software prompts you to select the station establishment method. Select the Set up at an
arbitrary locationoption.
2. Measure at least two or three control points using the Add button.
3. Under Settings you can modify the station set up tolerances. By tapping Report you get more
information about the quality of your station establishment.
4. Add at least one control point:
5. If you do not know the name of the reference point being selected when carrying out either
station establishment process, simply move the target to the point that you want to measure,
or point the total station at an already established target. The target indicator moves in the
map to that location, making it easy to identify and select the correct point from the map view.
6. The screen shows if the setup is within or outside the tolerance.
7. Tap Accept if the total station set up is within tolerance.
