7.1.7 Notes on tank adjustment
Tank adjustment reduces the effect of interference and ensures a higher
excess gain in difficult application conditions�
Carry out the tank adjustment only when the unit is installed�
For the tank adjustment it is necessary to enter an "adjustment distance" first�
Within this distance, starting from the process connection, interfering reflections
are compensated�
► Select an adjustment distance (a) so that the connection piece (S) and
structures in the tank (B) are completely detected�

For probe lengths L < 260 mm no tank adjustment is possible� The
parameter [tREF] is then not available� In this case:
► Adhere to all indicated installation distances (→ 7.1)�
No tank adjustment is necessary if all installation distances (→ 7.1) are
adhered to� The unit is then ready for operation without tank adjustment�
► In case of doubt carry out a tank adjustment (recommended!)�
