V-index error
The V-index error is the zero-point
error of the vertical encoding circle in
relation to the vertical axis of the
instrument.
The V-index error is set to "0.00"
before delivery.
All vertical angles are corrected with
the V-index error.
The instrument should
have adapted to the
ambient temperature and
should be protected
against warming from one side.
To determine the V-index error, aim
the telescope at a target about 100m
distant. The target must be
positioned within ±9° (±10 gon) of the
horizontal plane.
Activate the calibration
procedure (Refer to display
on page 30). The two-axis
compensator is turned off
automatically when determining the
V-index error.
This fact is shown by the
symbol.
Starts the measurement for
the vertical circle.
Afterwards, the display shows a
message asking for the telescope to
be turned to the other face.
