9.1 Starting depth (BSCAN START)
The starting depth BSCAN START is the starting thickness value. Under normal circumstances this
value will be set to zero in order to start measuring at 0.00 mm/inches.
The only time BSCAN START needs to be set to something other than zero is if you need to zoom
in on a specific measurement range. For example, consider a test material 1 inch in thickness in
which potential corrosion is only on the back surface and not possibly deeper than .200". In this
case, you may wish to set the BSCAN START at .700" to zoom in closer to the area where corrosion
is likely to be present. In turn, the BSCAN DEPTH might be set at 1.100" in order to cover the entire
range. This will result in better resolution for both the B-Scan and Scan Bar graphical presentations.
9.2 Depth (BSCAN DEPTH)
BSCAN DEPTH represents the overall viewable thickness range being tested. For example, if you
are measuring tank walls with a total thickness of .300", and BSCAN START is set to 0.000", you
might consider setting your BSCAN DEPTH value to 0.400" to cover the entire thickness range
being tested.
BSCAN DEPTH can be thought of as a zoom feature for both the B-Scan and the Scan Bar; the
larger the overall thickness range view (BSCAN DEPTH), the smaller the noticeable shifts in the
Scan Bar and B-Scan presentation. Therefore, it is best to set the BSCAN START and BSCAN
DEPTH to reasonable values that zoom in and optimise your graphic presentation.
