Modify the 3D Display during Collection
You can adjust how the data appear during data collection using the Toolbar soft keys and the Output
menu available in the 3D Collection Screen.
View Toggle:
Pressing this soft key toggles the 3D Collection Screen between a top down view of the
grid, the 2D profiles and 3D view of the grid simultaneously, just the 2D profile, and the 2D profile view
for hyperbola fitting. You can further modify the 3D grid appearance through the Output Menu.
Gain:
Increase or decrease the Display Gain during data collection by a factor ranging from -12-60 dB.
This can be used to adjust contrast for an entire profile by the same amount.
Output Menu
This menu provides options for modifying the appearance of your data during collection. The first six (6)
options are the same for 3D collection and 2D collection. None of these settings affect raw data.
H Cursor:
Changes the depth of the slice map
in the Grid Display in half inch increments.
Slice Thickness:
Adjusts the slice thickness
from zero (0) inches to the maximum selected
depth range in half inch increments. The slice
is centered on the location of the H Cursor.
Dielectric:
You can adjust the Dielectric
Constant during data collection from a value
of one (1) to eighty-one (81).
Colormap:
This menu option offers 30
available Colormap options (i.e. color tables).
Select the menu by pressing the Control Knob
or Enter key and then scroll through Colormap
#0-29.
Rotate:
You can rotate the grid from 0-358º
using the Control Knob. The rotation changes
in increments of 2º and you can start by
moving up from zero or down from 358º.
Combining Rotate with Viewpoint can create a
3D view of the data during collection.
Viewpoint:
Viewpoint adjusts the perspective
to view the grid. You can adjust the Viewpoint
from -0.40 to 1, where -0.40 will provide
almost a straight forward view of a 2D profile
as you would see during 2D data collection.
This will not preview through the Output menu
unless Viewpoint Toggle was selected from
the Toolbar.
Home:
Resets Rotate and Viewpoint back to
zero (0).
Marks on Grid:
This turns the grid marks on or off. Grid marks correspond with the location of the
profiles in the grid. Only adds marks to the lines where data have already been collected.
