Scanning Gain
AWS codes require that you apply a certain amount of scanning gain to the
Ref B
gain
value. This allows you to locate flaws that might be smaller or deeper in the test piece
than the reference flaw.
To add scanning gain
Use the
Gain
adjustment box to adjust the gain as necessary (see “Adjusting the
Gain (System Sensitivity)” on page 59 for instructions on using the
Gain
adjustment box).
To display a D indication rating value, the gated echo must peak at an amplitude less
than 110 % FSH (full-screen height). You may need to turn off the scanning gain, and
even make further gain adjustments, to bring the echo peak on screen.
