Averaging Procedure
Whenever more than one coordinate
for the same point is recorded, the
system does the following:
In any case, it carries out an
averaging procedure.
Depending on the Threshhold
Settings, either the difference
between the average and the
individual point coordinates or the
absolute coordinate differences
between two points in X, Y, Z and E,
N, H (with local coordinate system)
can be displayed. Limits for the
averaging procedure as well as for
the absolute coordinate differences
are also set in Threshold Settings.
Should a point fall within these
threshold settings and the system is
set to the averaging functionality, you
may press AVRG (F2) to display the
differences between the average and
the individual point coordinates.
The line Time to go changes to
depending to the OCCUPY counter
set Positions / Time at point.
Then, according to what has been set
in Occupation Settings, press STOP
(F1) and STORE (F1).
Once the point is stored, again the
OCUPY (F1) key becomes available
and the start time line is shown with
the current time and the seconds
rounded to zero. To start a new
occupation enter the next start time.
Then press OCUPY (F1).
The intervals are displayed with time
when they were recorded, and the
differences in position and height.
Should a point fall outside of these
threshold settings, this panel will be
accessed automatically. The asterisk
marks the measurement exceeding
the threshold settings. Common
reasons for this happening are an
incorrect antenna height or a wrong
point Id.
You may either:
Press ESC to return to the survey
screen, check and correct the
antenna height or point Id, then
rerecord the interval. Your previous,
incorrect interval will be deleted.
