Setting instrument coordinate and direction angle

When AP-L1A is set at a random position, by method of resection, sight the known points
and determine the instrument coordination with the data terminal.

Sight the known point and set the direction angle of AP-L1A with the data terminal.

Start of surveying

After all settings for AP-L1A and data terminal are complete, move prism and data terminal
to the first point.
In stake out operation, input identification of first point in the data terminal for tracking
status. Display shows the distance and direction between AP-L1A and target .

Execute survey or stake out.
When surveying or stake out is completed the first point, move to second point for tracking
status, and repeat survey as above.

Set coarse measurement mode for a moving prism and change to fine mode for collection or stake
out purposes. These can be changed in Distance measurement mode.

Data measured and displayed after optical path from instrument and prism is disturbed by a person
or car will be unstable for few seconds. Do not employ these measured data.

When tight accuracy is desired, it is recommended that an averaging option be used with the
measured data repeated 5 ~ 10 times.
