Calibrate (a, l, t, i, c and AiM)

The calibration procedure determines the following instrument errors in one process:
a Tilting axis error.
l, t Compensator longitudinal and transversal index errors.
i Vertical index error, related to the standing axis.
c Horizontal collimation error, also called line of sight error.
AiM Hz AiM zero point error for horizontal angle.
AiM V AiM zero point error for vertical angle.

AiM Hz and AiM V are excluded from calibration if you choose the "Calibrate without AiM" proce-
dure. AiM Hz and AiM V are included if you choose the "Calibrate All" procedure.

Aim the telescope accurately at a target at about 100 m
distance. The target must be positioned within ±9°/±10 gon
of the horizontal plane.
Motorised instruments change automatically to the other face.
It is recommended carefully fine-point to the target manually.
Aim the telescope accurately at a target at about 100 m
