1.2Overview of the method of proceeding

Record a reference echo and adjust the required record- ing level. The reference echo reflector may be disk shaped, a side drilled hole, or a backwall. The equiva- lent reflector size is then infinite. If a flaw echo occurs, the amplitude may exceed the DGS curve. In that case, the reflecting power of this natural flaw is greater than the reflecting power of the disk-shaped reflector at the same depth.

With a saturation over 100% and below 10%, the DGS curve is always horizontal.
