E) Echo Signal – Graphical full waveform representation of the echo signal dis-
played as an amplitude (vertical or “Y” axis) plotted against time (horizontal or
“X” axis), this time is then converted to a physical measurement and displayed
according.
F) Measurement Labels – The measurement labels are calculated and displayed
based on where the left side of the display has been set (Delay), and the overall
viewable area (Width) of the display. Note: The gray hash marks break the dis-
play up into 5 segments, or quadrants. The measurement labels correspond to
the measurement at each hash mark.
G) Units Label -Displays the current units of measurement (inches or millime-
ters).
H) Hot Menus -Each of the fields located under the waveform display are called
the Hot Menu Fields. These fields allow quick control of some of the fine adjust-
ments needed to control the display settings, measurement modes, and grid
memory control. All of these fields can be adjusted without having to activate the
tabbed menu items and searching through a variety of menus to make adjust-
ments.

C) Thickness reading – Digital readout of thickness (inches or millimeters).
D) B-Scan Display Area – This is the area representing where the B-Scan will be
drawn. Notice the range of the area in the diagram at 0.00” – 1.0” respectively.
E) Displayed B-Scan – Graphical presentation of the cross section, or side view
of the test material. The top, or accessible side of the material represented as
0.00”, and the bottom, or blind surface at .500”. You will notice the contour in the
B-Scan, indicating a very corroded bottom surface. The B-Scan is displayed from
right to left at a rate of 15 screens per second.
F) Measurement Labels – The measurement labels are calculated and displayed
based on where the left side of the display has been set (Delay), and the overall
viewable area (Width) of the display. Note: The gray hash marks break the dis-
play up into 5 segments, or quadrants. The measurement labels correspond to
the measurement at each hash mark.
G) Units Label -Display’s the current unit of measurement (inches or millime-
ters).
H) Hot Menus -Each of the fields located under the B-Scan display are called
the Hot Menu Fields. These fields allow quick control of some of the fine adjust-
ments needed to control the display settings, measurement modes, and grid
memory control. All of these fields can be adjusted without having to activate the
tabbed menu items and searching through a variety of menus to make adjust-
ments.
I) Scan Bar – The scan bar corresponds directly with thickness represented by
the horizontal labels on the on the display. As you can see from the diagram
above, the filled horizontal bar is displayed at .500”. This display can be very
useful when scanning materials in either B-Scan or Digits display views. It is
much easier to watch and notice deflections for flaws and pits using the scan
bar, rather than trying to notice changes in digital values. If the user is scanning
a pipe, for instance, and passes over a pit in the process, the scan bar will quick-
ly deflect and alarm the user to go back and search for the defect.
J) Contour (blind surface) – A view of the B-Scan displaying the blind side sur-
face contour of the material.
