The first Read line on the baseline is referred to as the Main Bang Blank while the second
red line is referred to as the Blank After First Received echo. The white line represents
the measured time interval between the two correct echoes.
To adjust any of the above settings, from the main measurement screen, simply use the
left, right, up or down arrow until the desired parameter is highlighted. In other words the
arrow keys will act as a mouse or cursor to highlight the desired parameter. As an
example, if the right arrow unit Rectify is highlighted, then press Menu/OK to adjust the
rectification mode by again using the right or left key to except, press F1=exit. You can
follow the same procedure for Gain, Blanking and Range. A newer feature in versions 1.7
or higher is the ability to show the thickness value in large numbers. When in A-scan
mode and using the left or right arrow, F3 will display Thickness, see below. When this is
press, the gauge will not show the A-Scan but rather the thickness in large numerals. To
go back to Waveform, press F3.
