Aim the telescope accurately at a target
at about 100 m distance or less if not
possible. The target must be positioned
at least 27°/30 gon above or beneath the
horizontal plane.
The procedure can be started in any tele-

Motorised instruments change automat-
ically to the other face.
The fine pointing has to be
performed manually.

TOOLS Tilting-Axis Adjustment II
MEAS
(F1) to measure the same target in the other face and to calculate
the tilting axis error.
If the error is bigger than the predefined limit, the procedure has to be
repeated. The tilting axis measurements of the current run are then rejected
and not averaged with the results from previous runs.
