DGS/AVG curve gain adjustments are applied to both the echo height and curve
height to maintain the amplitude ratio and, therefore, the sizing comparisons.
Figure 11-23 on page 179 shows a DGS/AVG setup with curve gain in use to provide
accurate echo-amplitude measurement by placing the echo close to 80 % FSH.

Registration Level Adjustment
The registration level of the DGS/AVG curve defines the height of the main curve. The
curve height represents the amplitude from a flat-bottom hole with a diameter of the
registration level at different depths. This is usually equal to the critical flaw size for
the application. The EPOCH 6LT allows you to adjust this registration level during a
live inspection.
