Adjusting the Tilting Axis Error

The tilting axis error is caused by the deviation between the mechanical tilting axis and
the line perpendicular to the vertical axis. This error affects horizontal angles. To
determine this error, it is necessary to point to a target located significantly below or
above the horizontal plane.
The horizontal collimation error has to be determined before starting this procedure.
1) Select Tools from the Main Menu.
2) Select Adjust from the Tools Menu.
3) Select Tilt Axis.
1. Level the instrument with the electronic level. Refer to "4 Operation" - "Level up
with the electronic level step-by-step".
