The device is operational just with empty adjustment. However, it is recommended to carry out a
“full adjustment” with the active zone being completely covered after empty adjustment. On the
basis of the values for the empty state / full state the device software determines the optimum
position of the switching thresholds between the two states. Using both adjustment criteria
(empty and full adjustment) results in the maximum operational reliability for the application. The
full adjustment can be repeated as often as you like. The stored value for the empty state is not
overwritten by the full adjustment. After a new empty adjustment both values are automatically
reset; the values defined last are overwritten.
7.4.2 Application as leakage detection

installation situation is changed, it is mandatory to perform the empty adjustment again.
If the device detects a medium after adjustment, its switching status changes.
