3 AUTOMATIC TRACKING / AUTOMATIC COLLIMATION
3.2 Automatic Collimation
The function enables the instrument to search and collimate automatically the center of the prism when
the telescopic is aimed at a prism roughly. (in the range of approx. ±5°)
Use this mode for the object which is stable.
You can select Fine or Course mode for the distance measurement in auto-collimation.
1
Collimate the target prism roughly using V/H
jog/shuttle.
2
Press the Auto-collimating icon.
The automatic collimation mode is set. The
instrument searches the prism and, when it is
found, “ Pi ” is heard.
The automatic collimation is completed.
3
Choose measuring modes by pressing the
operation keys.
Measuring starts.
Sample: Horizontal distance measuring
It is possible to use the auto collimation during
the star key mode.
In case the instrument could not find the prism during auto-collimating, the instrument returns to normal
mode after displaying the mark as follows.
If any key is pressed during auto-collimating, the auto-collimating mode is ended and the instrument
returns to normal mode.
After auto-collimating is finished, the instrument does not track the prism even if the prism is moved.
The auto-collimating can not be done correctly in the time of shaking prism, or under bad weather
condition for example, when the heat shimmer is generated in a great degree or when visibility is poor.
The above caution mark will be displayed after 10 seconds and the auto-collimating will be finished.
Use the operation keys on the telescope eyepiece side for key operation. If you use the
operation keys on the objective lens side, an error will be displayed and auto-collimation
will not start.
