Station setup options
Tap Options to configure Station setup to match the way that you prefer to work.
For other options in this screen, see To configure the conventional survey style.

The Default point names option determines the default values for the instrument and the backsight point name fields each time you perform a station setup. If you:
- Always use the same names for your instrument and backsight points, select Last used. Use this method if you always use the default instrument coordinates, or if you repeatedly set up on the same known point.
- Are performing a traverse type survey, select Traversing. When you start a new station setup, by default, the instrument uses the first foresight point observed from the last station setup for the Instrument point name, and the instrument point name used in the last station setup for the Backsight point name.
- Want to key in or select the instrument and backsight point names each time you perform a station setup, select All null.
- Want the software to automatically increment the instrument point name, select Auto increment.
Do not confuse the Last used option with the Use last survey menu option. The Last used option applies to a new station setup. The last values are used even across different jobs. The Use last menu option reinstates the last station setup. No new station setup is performed.

The Default heights option determines the default values for the Instrument height and Backsight point height fields each time you perform a station setup.
- If you always use the same heights for your instrument and backsight points, select Last used. This option is available only if you set the Default point names option to Last used.
- If you are using the Trimble traverse kit (so that the last measured foresight and instrument heights can be used as the new instrument and backsight heights), select Move forward. This option is available only if you set the Default point names option to Traversing.
- If you want to key in a new instrument and backsight height for each station setup, select All null.

If the instrument point does not exist, the default instrument coordinates are used. This is particularly useful if you work in a local coordinate system, and always set up your instrument on coordinate (0,0,0) or (1000N, 2000E, 100El), for example.
If you leave the Default instrument coordinates set to null, you can key in coordinates for instrument points that do not exist when you perform a station setup.
If you always set up your instrument on a known point then leave the Default instrument coordinates field set to null. This ensures that you do not accidentally use the default value if you incorrectly enter the name of the instrument point name.

This value is used only if an azimuth cannot be computed between the instrument and backsight points.
Always set up your instrument on a known point, and use a known azimuth, then leave the Default instrument coordinates and Default azimuth fields set to null. This ensures that you do not accidentally use default values if you incorrectly enter the name of the instrument and/or the backsight point names.

The software normally expects you to measure a backsight point to orient your survey. If your survey practice does not require you to measure to the backsight, clear the Measure backsight check box. The software automatically creates a virtual backsight, Backsightxxxx (where xxxx is a unique suffix, for example, Backsight0001), using the current instrument orientation as the azimuth.

When you enable the Advanced Geodetic check box in the Cogo settings screen, you can apply an additional scale factor to every conventional station setup. All measured horizontal distances are adjusted by this scale factor. To configure the scale factor settings, select Options during a station setup, station setup plus, or resection.
This station setup scale factor can be Free (computed) or Fixed. If you have chosen to compute a station setup scale factor, you must observe at least one distance to a backsight during the station setup so that a scale factor can be calculated.
The Station setup scale factor is not applied to point clouds captured using a Trimble SX10 scanning total station.
You can also apply a Neighborhood adjustment to all conventional foresight observations made from a Station setup plus or Resection, and to all GPS observations made in a job that has a valid GPS site calibration. See Neighborhood adjustment.
