The crosshairs of the telescope may not fully coincide with the centre of the
prism when viewed through the telescope. The remaining automatic aiming
offsets for the horizontal and vertical angles are measured by the automatic
aiming function and applied to the measured and displayed angles.
TS_005
If the prism is not in the field of view when Measure or Distance is pressed,
an automatic aiming search is started. For the automatic aiming search the
automatic aiming window is scanned line by line starting at the current tele-
scope position.

If the prism was not found

• Search can be pressed to search for the prism in an increased area. The
telescope move automatically.
Retry can be pressed to search for the prism under unfavourable condi-
•
tions. The telescope does not move. Make sure that the prism is within
the field of view.

If the prism was found

The automatic aiming measurement is performed to position the telescope to
the centre of the prism.
The automatic aiming window is a relative window based on the current tele-
scope position. The horizontal and vertical extent can be defined.
If no target is found after the prediction time and If no target found after
prediction then: Start fine search is set, then the prism is searched for with
automatic aiming using a dynamic automatic aiming window. This window cov-
ers a horizontal region from the position of loss of lock to the current tele-
scope position, and the same extent on the other side. The vertical dimension
of the dynamic window is one third of the horizontal expansion.
Refer to "22.1.1 Measure & Target".
PowerSearch
The PowerSearch module allows an automatic prism detection within a short
time period. The PowerSearch function can be started in the icon bar and con-
