RTK, or None
Shallow (Sh) and
Deep (Dp) soil EC
readings. If negative,
no data is being
saved.
Point size for EC,
OM and pH values;
adjust point size to
fill transects and
display spatial
structure to map.
Ranges used to map pH values. Each color
should have a unique range associated with
it. These are user-defined ranges and can
be changed at any time. If points appear
to be missing from the map, it could be that
they are out of the ranges selected. pH min
and pH max can be used as guidelines for
setting up the pH ranges. Up to five
divisions can be selected
These EC and OM
ranges are not user
selectable and are
set by the software
which gives each
range the same
number of points.
Colors for the graphs
can be set here, by
clicking on the color
box and selecting a
new color.
Control used to
change
between EC
arrays

OM/EC Comm.
and pH Comm.
Lights; when
green these
indicate there is
communication
with the
controllers.
Cancel Search
– This stops
the software
from searching
for the pH or
OM controllers.
This is helpful
when the
operator only
wants to map
EC and OM, or
in previewing
data that was
previously
collected.
