S Sound Path: the actual distance of the sound wave from the surface of the work piece to the flaw.
X Horizontal Distance: the horizontal distance of the sound wave from the point of incidence to the
flaw.
Y Vertical Distance: the vertical distance of the sound wave from the surface of the work piece to
the flaw.
3.1.7 Reject
After you adjust to a value, the echo below the value can be cleaned. For instance, you can remove
the structural noise of the detected work piece. The reject setting is shown by % on the screen, and the
adjustment range is 0-80%.
On the parameter menu, press to activate the function. Press (up) or (down)
to select the reject submenu, then press (left) or (right) to adjust the values.
You should handle this function with great caution, as it may happen that you suppress echoes from
flaws as well. In addition, some specifications expressly forbid using the reject function.
3.1.8 Wave Height Readings
Ha% The percentage of the waveform accounting for of the screen height in windows.
dBa The dB difference of the waveform relative gate can be shown in windows. When you use
this function, you should use Gate A to catch the echoes. Otherwise, it will result in error in reading.
SL In the windows, the dB difference of the quantitative line relative to DAC curve will be
shown. If there is no DAC curve, then it displays SL ----.
Hint:
on the parameter menu, the 8 submenus are shown on two screens - the former five ones on
one screen, and the latter three ones on the other screen. You can switch among them by pressing .
3.2 Setting Menu

3.2.1 Waveform Filling
