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.
