– To delete the point shown in this screen
( for example because of large residuals),
press
[F3] Del.
– To accept the current points and proceed to
the next screen, press
[F4] o.k..
11. The
Station Coordinates screen displays
the current station solution.
B
Tip – From the Station Coordinates screen or Scale screen,
you can change a point name or code or verify data by
pressing .
12. To accept the computed station coordinates,
press
[F4] o.k. in the Station
Coordinates screen.
The
Resection screen shows a quality
summary. These values indicate how good your
computed station coordinates fit with the points
used in the resection. For example, if your are
using ground coordinates, and your scale value,
m, is close to 1, you have established good
control in your station setup.
13. In the
Resection screen, do one of the
following:
– To return to the observation screen, press
[F1] Rept.
Note – If you decide to go back and remeasure the
corresponding points, the observed points data after the
point you are going to remeasure is lost. Trimble
recommends that you complete the measurement after
three backsight points, and then delete and re-measure
the corresponding direction. New measurements are
added at the end. As a result, the assignments of the point
codes (A, B, etc.) are shifted.
– To change the scale, m, press
[F2] (m), where:
m - calculated scale
Om - orientation unknown
sO - standard deviation of the weighting
unit (mean point error)
– To record the station data and finish the
setup, press
[F4] o.k.
If the scale is outside the permissible range, an
error message appears. If you edit the scale value
the
corr. field is updated when you press [ENT].
