If the speed of the prism is too fast, the target may be lost. Make sure that
the speed does not exceed the figure given in the technical data.
Selecting
Target lock on
in the icon menu, will immediately activate an auto-
matic aiming search to find the prism. Alternatively, as long as
Aim at target
is
set to

, then pressing

ment to Hz/V
and starts a PowerSearch or automatic aiming search to find the
prism. When the prism is found, the instrument locks onto the prism. The
instrument follows the moving prism and the automatic aiming function
remains active.
When the instrument is locked onto a prism, lock may be lost if the movement
of the prism is too fast for the instrument to follow or the prism is hidden
behind an object. After lock is lost, the prediction, as set in
Target Search
is
used to find the prism again.
The automatic aiming function is still active.
Whenever the prism is moved in the field of view during the prediction and any
other search periods, the instrument locks automatically to the prism.

Prediction
As long as the prism is being tracked by the instrument a mathematical filter
continuously calculates the average speed and direction of the prism. If the
line of sight between instrument and prism is disturbed, the instrument keeps
on moving using these calculated values. This behaviour is called prediction.
The prediction time can be configured. During prediction, the LOCK icon is dis-
played and if the prism comes into the instruments field of view again the
automatic aiming will lock to the prism.
After prediction, the prism is searched for depending on the settings in
Target
Search
.
•
If no target found after prediction then: Wait & lock
. If the prism
moves into the field of view, the prism is not searched for until
