10. TARGET SIGHTING AND MEASUREMENT
Search pattern
The search pattern is the rotating method of telescope and instrument to find the
target prism in search mode.
In Pattern "1" instrument starts searching the prism at the point where the prism is
lost and gradually expands the searching area in vertical direction, keeping the
horizontal angular width.
Pattern "2" can be selected to search for the prism. The search pattern tries to
locate the prism in a very short time.
In pattern "3", instrument starts searching the prism at the point where the prism is
lost and gradually expands the searching area in horizontal and vertical direction.
In every pattern, the searching is arranged to 2 times until the reflector is found.
The auto tracking mode changes to manual mode when the reflector could not
found out within 2 times searching, and returns to the point where the reflector is
lost.
TURN
This option allows the user to set a tolerance range for setting accuracy (after rotation to a specified angle).
For example, when this option is set to 30" and
[INV]
,
[H.TURN]
, or
[TURN]
is pressed, the instrument
will stop rotation within 30" of the specified rotation angle.
Tracking Meas.
This setting refers to angle display when performing Auto Tracking.
When set to "Standard", the angle value is corrected by the image sensor all the time during Auto Tracking.
"Standard" is effective when measuring a moving object.
In the "Fixed Averaging" setting, the angle value corrected by the image sensor is averaged and then fixed
when the iX automatically detects the rest state of target during Auto Tracking. The angle value will be
fixed until the target starts moving again. Therefore, the angle display during the target is in resting state
will be stabilized and scintillation effect will be reduced as well. "Fixed Averaging" is effective when
measuring a target in resting state during Auto Tracking.
Search operation during Auto Pointing
When the target enters the field-of-view within the set limit (setting of "Auto AIM" and "Measure Acc.") for
Auto Pointing completion, the instrument stops moving, calculates the offset between the target and
telescope reticle by image processing, then compensates the angle measurement value obtained from the
encoder. This compensation enables accurate sighting in a short time. Even though the target and
telescope reticle may appear to be misaligned, actual angle value of center of the target is displayed.
Compensated values are displayed in blue.
If the instrument is rotated (manually or using the Jogs) more than 10", compensation will be canceled,
the angle reverts to that obtained from the encoder, and the angle values are once again displayed in
black. Compensation is automatically performed when performing Auto Tracking. Terminating Auto
Tracking or powering OFF the instrument will cancel the compensation function.
