CHAPTER SEVEN
USING THE DISPLAY OPTIONS
A key feature of the MMX-7 is the ability to toggle between two different display
options; Digits & B-Scan. All views provide a digital readout of the base material
thickness measurement, while also displaying the min/max values if scan is enabled.
The B-Scan display is 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. The scan bar gives the user a
visual indication when a flaw or defect passed over during the scan process. The
scan bar will deflect off of the defect and return back to the overall thickness.
Visually, this is much easier to notice than watching for changes in the digital value
displayed. The scan bar has also been included in the large digits display mode for
the same purpose.
Note: The following chapter outlines some of the fine adjustment features of the
MMX-7. The MMX-7 has two different display options (Large Digits and B-Scan).
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 MMX-7 at a later
time, the user must save the modified settings in one of the setup locations prior to
powering off the unit. Refer page 84 for more information on setups.
