Gain
To provide height of the first
delay line echo reaching at
least 80…100% of
A-Scan
height
To provide height of the
maximal material back echo
in the sequence of at least
two back echoes covered by
Gate A
reaching at least
80…100% of
A-Scan
height.
It is also necessary that at
least one back echo to follow
