When "Right" or "Left -> Right" selected
Pattern 1: From right-most point to left-most point.
Pattern 2: Center point observed first. Then the point immediately to the right of the center point.
Remaining points can then be observed in any order.
Pattern 3: Method using 2 prisms. Center point observed first followed by the point immediately to the
right. Subsequent observations can be in whatever order is the most efficient for operation with
2 prisms.
When "Left -> Right" or "Right -> Left" selected,
observation of a subsequent cross-section can be
switched automatically to the opposite direction upon
completion of the previous cross-section observation. This
method minimizes the walking distance to the next starting
point when measuring multiple cross-sections.

Cross survey data review
Cross-section data recorded in a JOB is displayed as
shown at right."Offset" represents the distance calculated
from the center point coordinates and measurement point
coordinates.
