This menu item is only available, if you have chosen interface meas-
urement under the menu item "Application". In this menu item you can
enter if there is a superimposed gas phase in your application.
Only set the function to "Yes", if the gas phase is permanently pre-

This menu item is only available if you have selected interface meas-
urement under the menu item "Application". In this menu item you can
enter the dielectric constant of the upper medium.
You can directly enter the dielectric constant of the upper medium or
have the value determined by the instrument.
If you want the dielectric constant to be determined by the instrument,
you have to enter the measured or known distance to the interface.
In this menu item you can enter the max. adjustment for the level. With
interface measurement this is the maximum total level.
Adjust the requested percentage value with [+] and store with [OK].
Enter the appropriate distance value in m (corresponding to the
percentage value) for the full vessel. The distance refers to the sensor
reference plane (seal surface of the process fitting). Keep in mind that
the max. level must lie below the dead zone.
In this menu item you can enter the min. adjustment for the level. With
