ATR collimation
(Available for TCA and TCRA
versions only)
The ATR collimation error is the
combined horizontal and vertical an-
gular divergence of the line of sight
from the axis of the CCD camera.
The collimation procedure includes,
optionally, the determination of the
line-of-sight error and the vertical-
index error.
The correction for the ATR collimation
errors is always applied regardless of
the "ON/OFF" status of the Hz-
correction setting. (See section
"Deactivating the instrument-error
correction").

To define the ATR collimation error, a
prism must be accurately targeted at
a distance of about 100 m. 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 ATR target
recognition is automatically switched
on. This fact is shown by the
symbol. The display shows the
current horizontal and vertical ATR
collimation errors.
