Out of tolerance measurements

After each measurement, the Monitoring software checks to see if the measurement is within the tolerance specified in the job. The software warns if it is out of tolerance and the deltas are shown.

Two types of tolerances are set in the job:

  • Horizontal and vertical foresight displacement tolerances.

    If any of the points have moved more than the specified tolerance, the deltas are shown in the Deltas view and the point is listed in the Warnings view. You can also see this information in the Displacements report

  • Horizontal and vertical backsight residual tolerances.
    • If the backsight observations are outside the residual tolerance, the backsight information is shown in the Residuals view.

If an alert appears at the end of an epoch for backsight residuals, the Monitoring software will not show a point alert for any displacements in the foresight measurements for the observed epoch.
