7.2.7 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�
► Observe safety distance (b ≥ 250 mm) to the level or the rod end�

For probe lengths L < 260 mm no tank adjustment is possible� The

► Adhere to all indicated installation distances (→ 7.2)�
