7.3 Adjusting the B-Scan Start (B-ST) & Depth (B-DEP)
In order to use the B-Scan and Scan Bar features of the
PVX-B
effectively, the
starting depth and overall depth must be setup correctly. This can be adjusted using
the
B-ST (start)
and the
B-DEP (depth)
features of the
PVX-B
. The
B-ST
refers to
the starting depth or thickness value displayed. Example: If you want your B-Scan
or Scan Bar to start at a zero thickness value, then
B-ST
must be set to 0.000”. If
you want the B-Scan and Scan Bar to start displaying at .125”, then
B-ST
must be
set to .125”.
B-DEP
represents overall viewable thickness range being tested.
Example: If your measuring tank walls with a total thickness of .300”, and your
B-ST
has been set to 0.000”, you might consider setting your
B-DEP
value to something
like 0.400” to cover the entire thickness range being tested. You might also consider
B-DEP
as a zoom feature for both the B-Scan and Scan Bar. Why? Because the
larger the overall thickness range view
(B-DEP)
, the smaller the noticeable shifts in
the Scan Bar and B-Scan presentation. Therefore, it’s best to set the
B-ST
and
B-
DEP
to reasonable values that zoom in and optimize your graphic representations.
Overall range (B-DEP)
Once again, just to reiterate, B-DEP is the overall viewable thickness range being
tested. This should be set to a value slightly larger than the expected maximum
range being measured. The procedures to adjust the overall thickness range viewed
(B-DEP)
are outlined below:
