If you cannot maintain this distance, you should carry out a false
signal storage during setup. This applies particularly if buildup on the
vessel wall is expected. In such a case, it is recommended to repeat
the false signal storage at a later date with existing buildup.
Mounting should not be too close to the inflowing material as the
microwave signal will be interferred. The optimum mounting position is
on the opposite of the filling. To avoid strong pollution, the distance to
the filter or dust extraction must be as big as possible.
