Note
The effective range of the automatic false echo suppression sets the end point of the
determined TVT distance.
Determine the effective range of the automatic false echo suppression by measuring
the actual distance from the transmitter reference point to the material surface. Use
a cable or measuring tape.

Make sure that the material level is below all known installations when using the
" Auto false echo suppression wizard" to determine the TVT. Ideally the vessel
should be empty or almost empty.
Note the distance to the material level when determining the echo profile and
set the value in parameter " Effective range of automatic false echo suppression"
to a smaller distance to avoid suppression of the material echo.
If an agitator is used, it should be in operation.
