Scenario Four
You have only one known point on a job.
Solution
You have two options in this situation. One, you can assume an
azimuth for an arbitrary backsight reference and rotate the job later
using the Rotate routine once you have determined the actual
orientation.
Secondly, you can use the Sun Shot routine to determine an azimuth
to an arbitrary reference.
Summary
In general, you would follow these steps when you begin working on a
job.
1. Create a new job or open an existing job.
2. Setup over the Occupy Point .
3. Aim the total station toward the backsight and zero the
horizontal angle on the instrument.
4. Fill in the Backsight Setup screen and tap
6ROYH , then &ORVH . If
the Always Prompt for Backsight Check option is checked in the
Job | Settings | General screen, you will be prompted to check
your backsight.
5. Start your survey.
Note: You should enter the correct Height of Instrument and Height of
Backsight distances in the Backsight Setup screen if you plan to check
your backsight using the Check by Distance routine.
