CHAPTER SEVEN

USING THE DIGITS & B -SCAN DISPLAYS

A key feature of the CMX is the ability to toggle between two different display options, Digits and B-Scan. The Digits view provides the user with a large digital readout of the thickness. Both views also include a scan bar features that uses a bar graph to indicate thickness. The Scan bar can be very handy while scanning a tank or pipe wall by graphically displaying deflections from pits or internal flaws, rather than having to constantly watch for changes in the digital readout. It’s just another visual aid to alarm the user whe n something out of the ordinary has been detected.

The B-Scan display is also very useful when scanning surfaces and viewing the cross section of the test material. It provides a convenient way of visually profiling, or drawing a picture of, the blind surfaces during a scan. The B-Scan display is also equipped with a scan bar representing the overall thickness. Once again, the scan bar gives the user a visual indication when a flaw or defect has been passed over during the scan process. The scan bar will deflect off of the defect and return back to the overall thickness. In this chapter we’ll outline some of the fine adjustment features of the CMX. We’ll take a better look at these options in this chapter.

Note: In order to recall and use the new adjustments made to the CMX at a later time, the user must save the modified settings in one of the setup locations . Refer page 86 for more information on setups.
