Station setup plus, resection, and rounds options

Rounds options control the order in which observations are taken, and how many observations are made when measuring rounds.

To configure these settings, tap Options in the Station setup plus, Resection, or Measure rounds screen.

  • Face 1 only – observations are taken only on face 1
  • Face1...face 2... – all face 1 observations are taken to all points and then all face 2 observations are taken to all points
  • Face 1/face 2... – face 1 and then face 2 observations are taken to the first point, face 1 and then face 2 observations are taken to the next point, and so on

When the Face order is set to Face 1...face 2..., set the Observation order to:

  • 123...123 – to take observations on face 2 in the same order as the observations on face 1
  • 123...321 – to take observations on face 2 in the reverse order to the observations on face 1

When the Face order is set to Face 1 only or Face 1/face 2..., set the Observation order to:

  • 123...123 – to take each round of observations in the same order
  • 123...321 – to take every alternate round of observations in the opposite order

This option is not available during Station setup plus or Resection.

This option can be used to measure multiple sets of face 1 observations, or face 1 and face 2 observations to a point per round of observations. The maximum number of sets of observations per point per round is 10.

Before using this option make sure this data collection technique matches your QA/QC requirements.

If Face order is set to collect face 1 and face 2 observations, the Sets per point was set to 3, and the Number of rounds was set to 1, then the total number of observations to each point would be; 2 x 3 x 1 = 6. Setting the Sets per point option to a number greater than 1 enables you to collect more than one set of observations to a point with only one visit to that location.

Enter the number of times the software works through the rounds list and takes observations to each point in the list.

The Automate rounds option is available for Trimble servo total stations. When you select Automate rounds, the instrument automatically completes all rounds after the rounds list has been built.

Targets observed without Autolock are automatically paused.

When using Automate rounds you can configure the software to automatically skip obstructed foresight targets.

When Automated rounds is enabled, monitoring controls are also enabled. Enter a value for the time delay between automated rounds. A 3‑second delay between automated rounds enables you to check the standard deviations before the next round starts automatically.

With Trimble servo total stations, you can automatically measure to non‑active targets. To do this, select the Auto‑measure passive targets check box.

If you select the Auto‑measure passive targets check box, manually observed targets are automatically measured rather than paused. If you clear this check box, the software prompts you to aim the instrument to non‑active targets.

If a target has been blocked, the instrument tries to measure the point for up to 60 seconds. After 60 seconds has elapsed it skips the observation and moves to the next point in the rounds list.

If the instrument cannot measure the point and Skip obstructed foresights is enabled, it skips that point and moves onto the next point in the rounds list.

If the instrument cannot measure the point and Skip obstructed foresights is disabled, a message appears after 60 seconds to indicate that the prism is obstructed. The software continues to try to measure to the target until instructed to skip the point. To do this, tap OK for the obstructed prism message, tap Pause and then tap Skip.

If a point is skipped in one round, all subsequent rounds continue to prompt for observations to that point.

When one observation from a pair of face 1 and face 2 observations has been skipped, the unused observation is automatically deleted. Deleted observations are stored in the job and can be restored ("undeleted"). Restored observations can be processed in the office software, but are not automatically used to recompute Mean Turned Angle (MTA) records in the Trimble Access software.

Backsight observations cannot be skipped using the Skip obstructed foresights option.
