# To complete a station setup plus

Select Station setup plus to make observations to one or more backsight points, or to obtain better quality control of your observations.

1. Tap and select Measure / <Style name> / Station setup plus.
   1. When prompted, use the electronic level to level the instrument. Tap Accept.

   2. Set the corrections associated with the instrument.

      If the Corrections screen does not appear, tap Options and enter the correction information.

   3. Enter the instrument point name and the instrument height. See Station coordinates and instrument height.
   4. Tap Options to configure the number of observations to make and the order in which to take them. Make sure the Face order setting is correct. You cannot change this setting after you start measuring points. See Station setup plus, resection, and rounds options.
   5. Tap Accept.
2. To measure the first point:

   1. Enter the first Point name and the Code, if required.

   2. By default the Backsight check box is selected.

      If the station setup point is a traverse station that you plan to adjust, do not measure more than one backsight point. Clear the Backsight check box for any additional points so that they are measured as foresights.

   3. Enter the Azimuth.

   4. Choose an option in the Method field.

   5. Enter the Target height.

      Make sure the target height and prism constant values are correct as you measure each point. You cannot change these values in subsequent rounds.

   6. Sight the target and then tap Measure.

      If you measure to static targets when there are two prisms close together, use FineLock or Long Range FineLock technology.

      If you are using a Trimble VX spatial station or Trimble S Series total station and the measurement is likely to be interrupted, for example, when measuring in traffic, select the Interrupted target measurement check box in the Target controls screen.

   The software shows the residual information for the observation.

3. Use the information in the Residuals screen to review the quality of the observations and remove poor observations. See To review observation residuals and setup results.

4. To observe more points, tap +Point.

   To include foresight points during station setup plus, clear the Backsight check box. Foresight points do not contribute to the station setup result.

5. To take further measurements to points already measured (that is, measure rounds of observations):

1. Tap End face.

2. If you are using a servo or robotic instrument to measure a known (coordinated) point, tap Turn. Alternatively, to automatically turn a servo instrument to the point, set the Servo auto turn field in the survey style to HA & VA or HA only.

   When using servo or robotic instruments, check that the instrument has sighted the target accurately. When measuring a DR target with a Trimble total station with automated rounds, the software pauses to allow you to sight to the target. You must manually sight and measure the point to continue.

3. When the end of the rounds list is reached, if points have been skipped the software prompts you to return to observe the points that were skipped during that round. The observations can be skipped again if required.

6. When you have completed all observations, tap Results to view the station setup results.
7. Tap Store.
