Sun Shot Procedure Summary
1. Point the telescope ahead of the path of the sun and lock the
horizontal movement of the total station.
2. Immediately record the horizontal angle from the total station
using the Take Shot button.
3. When the target becomes properly aligned with the crosshairs,
record the current time as accurately as possible. The time can
be automatically read from the data collector using the
Get Local Time button, or measured from an external time piece
and manually entered in the appropriate fields.
