Auto False Echo Suppression
If you have a vessel with known obstructions, we recommend using Auto False Echo
Suppression to prevent false echo detection. See TVT setup (2.8.7.) on page 94 for
instructions.
This feature can also be used if SITRANS LR250 displays a false high level, or the reading
is fluctuating between the correct level and a false high level.
