Total Station Data Errors

If a point ID is displayed in red in the Project Explorer, there is a computational error associated with the point. For instructions on viewing computational error messages, see Select from the Flags Pane.

The following total station-related computational errors can occur:

Error message	Description
Setup failed to compute	An undefined problem caused all setup computations to fail. No further information is possible.
Using check observation to backsight as fallback	This error occurs when there is only one check observation available to the backsight and it is being used to define the backsight. (Typically, the software does not use check observations for any real computations.)
Azimuth to backsight missing or not computable	This error occurs when the backsight azimuth is not present or some coordinates defining the azimuth are disabled.
Some backsight observations are missing or disabled	This error occurs when some or all backsight observations are either disabled or not present.
Resection computation not possible	This error occurs when numerical problems occurred in the resection mathematics.
