Backsight by azimuth

|

• The station has been placed on a point of known coordinates and the orientation is determined through the measurement of a known azimuth.

• Select Yes. Station position is known.

• Select Backsight by azimuth.

  

  • Station: name of the station. Select a point existing in the job.

  • Instrument height: elevation of the total station from the ground. It is possible to calculate the height of the instrument.

  • Code: code to assign to the station point in case a new point is created.

  • E, N, Z: coordinates of the station. When an existing point was selected, the values cannot be edited.

• Click Atmospheric coeff to change the atmospheric coefficients.

• Click Next to proceed to define the backsight point.

  

  • Azimuth: the azimuth between the position of the station and the reference point is calculated.

  • Circle: define how to set the horizontal angle of the station:

    • Current value: the angle of the station is not modified.

    • Zero: the angle of the station is reset to the reference point.

    • Azimuth: the angle of the station is set to the azimuth value.

  • Store backsight point: enables the storing in the point list of the backsight point.

  • Press Next to measure the backsight point.

    

• Aim the point of orientation.

• Tap Measure.

• The calculated data and the differences are displayed.

• Tap Accept setup to confirm set data and complete procedure.
