Sensor parameter adjustment Gating out of false signals carried out
In bulk solids applications, implementing a false
signal suppression is generally not recommended.
The accuracy of bulk solid applications depends
considerably on the application. Hard and fast
accuracy specifications are thus not available.
Deviation see diagrams
Depending on the installation conditions, there can
be deviations which can be rectified with an
adaptation of the adjustment or a change of the
measured value offset in the DTM service mode.
