TCA and TCRA instruments are
motorized and equipped with
Automatic Target Recognition (ATR)
coaxially in the telescope. The guide
light (EGL), mounted on the
telescope, is
optional.
ATR mode
These instruments permit automatic
angle and distance measurements to
normal prisms and reduce the tedium
of precise visual sighting to prisms.
The prism is sighted with the optical
sight only. Initiating a distance
measurement will turn the instrument
with the help of the motors to sight
the prism-centre automatically.
The angles V and Hz are measured
to the centre of the prism completion
of the distance measurement.
Automatic Target Recognition ATR / LOCK
LOCK mode
Lock mode will enable TCA
instruments to follow a moving prism.
Distances can be measured
whenever the prism stops for a short
time ("Stop and Go mode").
If the assistant changes the
location too quickly, the
target may be lost. Make sure that
the speed does not exceed the figure
given in the technical data.
As with all other instrument
errors, the collimation error
of the automatic target recognition
(ATR) must be redetermined
periodically (Refer to chapter
"Checking and Adjusting").

Quick Prism Search with
PowerSearch
The PowerSearch sensor consists
of a transmitter (1) and a receiver (2).
Both are installed in the lower part of
the telescope.
When PowerSearch is activated, the
instrument starts to rotate around its
standing axis.The transmitter emits a
vertical laser swath.
