7.11 Reviewing, Re-collecting & Skipping Lines
During grid collection, if you need to review a previous line:
1. Press Grid Line +/- on the Display Unit or
2. Use the 4-way directional arrows on the Display Unit or Sensor Head
The white line on the grid will correspond to whatever line is selected, and the GPR Line is
displayed (if that line has been collected).
Occasionally, there may be a need to re-collect a line of data, if you went too fast, veered off the
line, or knew that your starting position was off. Go to the line that requires re-collection and
press
Start on the Display Unit , Enter on the Sensor Head or the Bluetooth Trigger . You will
be prompted to confirm that you would like to overwrite the line (Figure 7-10).
Figure 7-10: Overwriting a grid line.
If you need to skip a series of lines (due to an obstruction, for example), move to the desired
grid line using any of the methods above. You can still process the data to create depth slices
even if you are missing lines in the grid; there will just be a blank area where no data was
collected.
7.12 SliceView
Once you have finished collecting the grid, press the SliceView button to generate depth slices
( Section 8 explains viewing depth slices). Before the data is processed, the Concrete Cal is
automatically calculated from all the grid data. This value is the speed the GPR signal travels in
the concrete and an accurate value is important for processing the data to create images with
the highest clarity.
