7.3 Adjusting the B-Scan Start (B-START) & Depth (B-DEPTH)

In order to use the B-Scan and Scan Bar features of the CMX effectively, the starting depth and overall depth must be setup correctly. This can be adjusted using the B- START and the B-DEPTHfeatures of the CMX. The B-STARTrefers 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-STARTmust be set to 0.000”. If you want the B-Scan and Scan Bar to start displaying at .125”, then B-STARTmust be set to

.125”. B-DEPTHrepresents overall viewable thickness range being tested. Example: If your measuring tank walls with a total thickness of .300”, and your B- START has been set to 0.000”, you might consider setting your B-DEPTHvalue to something like 0.400” to cover the entire thickness range being tested. You might also consider B-DEPTHas a zoom feature for both the B-Scan and Scan Bar. Why? Because the larger the overall thickness range view (B-DEPTH), the smaller the noticeable shifts in the Scan Bar and B-Scan presentation. Therefore, it’s best to set the B-STARTand B-DEPTHto reasonable values that zoom in and optimize your graphic presentation.

Starting depth (B -START)

The starting B-START, or starting depth, is the starting thickness value. Often times this value will simply be set to zero in order to start measuring at 0.000”. The only time this value will be set to something other than zero, is if the user needs to zoom in even closer. When will this be the case? If the user is testing a material that’s 1 inch in thickness and knows that the potential corrosion is only on the back surface of the material and not possibly deeper than .200”. In this case, the user may wish to set the B-ST at .700” to zoom in closer to the actual area being tested. In turn, the B- DEP might be set at 1.100” in order to cover the entire range respectively. This will offer the user better resolution for both the B-Scan and Scan Bar graphical presentations.

Note: Once the range is set, it will remain the same for all the views respectively.

The procedures to adjust the starting depth (B-START)are outlined below:
