Line of sight
The line-of-sight error c is the
divergence of the line of sight from a
line perpendicular to the tilting axis.
The line-of-sight error is adjusted and
reduced to "0.00" before delivery
from the factory.
Horizontal angles are only corrected
by this line of sight error when the
correction is turned "ON" (setting in
accordance with section
"Deactivating the instrument-error
correction"). To determine the line-of-
sight error, aim the
telescope at a target about
100m distant. The target
must lie within ±9° (±10 gon) of the
horizontal plane.
The procedure is analogous to that of
determining the V-index error.
Activates the calibration
procedure. (Refer to display
on page 30).
The two-axis compensator is turned
off automatically when determining
the line-of-sight error.
This fact is shown by the
symbol.
Perform the measurement.
Afterwards, a message in the display
prompts you 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 the instrument is ready to
measure. The user is made aware by
an acoustic signal that the
key
is redefined as "OK".
