Tilting axis
The deviation between the mechanical tilting axis and the line perpendicular to
the vertical axis causes the tilting-axis error (a).
This error affects horizontal angles. The effect is zero in the horizon and
increases with steep sights. To determine this error, it is necessary to point to
a target located significantly below or above the horizontal plane. To avoid
influences from the horizontal collimation error (c), the horizontal collimation
has to be determined prior to the tilting-axis error.

Vertical index error
A vertical index error (i) exists, if the 0° mark of the vertical circle reading does
not coincide with the mechanical vertical axis of the instrument, also called
standing axis.
