Check by Distance Results
Occupy: is the current occupy point.
Backsight: is the current backsight point.
Zenith: is the zenith angle measured by the total station.
Slope Dist: is the slope distance measured by the total station.
HD Error: is the horizontal distance between the backsight point that
was shot and the backsight point stored in the job. A negative value
indicates that the point shot is closer to the total station than the
point in the job.
VD Error: is the vertical distance between the backsight point that
was shot and the backsight point stored in the job.
Check by Angle Results
Circle: is the horizontal angle that was measured by the total station.
Azimuth: is the known azimuth to the current backsight.
Error: is the difference between the two above angles.
Backsight Circle Dialog Box
The Backsight Circle dialog box is used to modify the horizontal angle
read from a total station so that the resulting angle is an azimuth.
Backsight Circle: is the angle that will be subtracted from all
horizontal angles read from the total station or entered manually
when data collecting in manual mode.
6HW : Sets the value entered in the Backsight Circle field as the
backsight circle and returns to the previous screen.
Note: Closing this dialog box without tapping the 6HW button will
result in no changes made to the original backsight circle.
