Tilting axis
The tilting-axis error a is the deviation
of the tilting axis from a line
perpendicular to the vertical axis.
The tilting-axis error is adjusted to
"0.00" before delivery.
The horizontal angles are only
corrected by the tilting axis error
when the Hz-correction is turned
"ON" (setting in accordance with
section "Deactivating the instrument-
error correction").
Tilting axis
Vertical axis
To determine the tilting-
axis error, aim the
telescope at a target about
100m distant. The target
must be positioned at least ±27°
(±30 gon) above or beneath the
horizontal plane. The two-axis
compensator is turned off
automatically during determination of
the tilting-axis error.
This fact is shown by the
symbol.
Start measurement.
Afterwards, a message in the
display prompts the user to change
telescope face.
If the differences between the hori-
zontal and vertical angles do not
exceed ±27' (±0.5 gon), the display
shows that it is ready to measure.
The user is made aware by an
acoustic signal that the
key is
redefined as "OK".
