" 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 " auto false echo suppression" to a smaller distance to avoid
suppression of the material echo.
If an agitator (whisk) is available, it should be in operation.
As soon as the wizard is successfully completed, parameter " Auto false echo
suppression" is set to " Activated" and the determined TVT curve is used.

Accepts the settings as the last step in the wizard.
