8. You can now either proceed with point B
measurement, or remeasure point A. Do one of
the following:
– To take a measurement to point B, press
[F2]
B.
–To remeasure point A, press
[F1] A.
After at least two measurements, approximate
coordinates are calculated and the deviation to
the current measurement appears:
–
vy: residual in Y-direction
–
vx: residual in X-direction
–
vz: residual in Z-direction
Based on the quality of your residual data, you
may want to add more points to the resection, or
remeasure your last point (point B).
Note – If the angle between known point A and known
point B (measured from the station point) is extremely
acute or extremely oblique, the resulting solution will be
less reliable geometrically. For geometric reliability, select
known point locations (or station point locations) that are
widely spaced.
9. Do one of the following:
– To remeasure to point B, press
[F1] B.
– To measure to the next point, press
[F2] C.
– To finish observation and proceed to the
Residual screen, press
[F4] END.
After completing the observation, the solution
residuals for each point are displayed for review. You
can delete points from the solution, add more points to
the calculation, or accept the current points.
10. In the Residuals check screen, do one of the
following:
– To show the previous or next point
observation result, press
[^] or [v].
– To add more points to the observation,
press
[F1] More.
