• Position adjustment (zero point correction)
• Setting the lower and upper pressure value and assigning to the lower or upper level
value
• To reset the device, see "Function of the operating elements" section, table .
• The pressure applied must be within the nominal pressure limits of the respective
sensor module. See information on the nameplate.
• Operation must be unlocked, see "Unlocking/locking configuration" section →  42.
• The  and  keys have a function only in the case of the "Calibration mode wet"
setting. The keys have no function in other settings.
• "Overview of level measurement" →  49
• The device is configured for the "Level" measuring mode as standard. You can
change the measuring mode using the "Measuring mode" parameter, see
"Commissioning with an operating menu" section.→  45
The following parameters are set to the following values at the factory: →  45.
- "Level selection": In pressure
- "Calibration Mode": Wet
"Unit before lin." or "Linear range limit": %
- "Empty calib.": 0.0 (corresponds to 4 mA value)
- "Full calib.": 100.0 (corresponds to 20 mA value)
- "Empty pressure": 0.0
- "Full pressure": 100.0
These parameters can be changed only via the local display or remote control, such
as FieldCare.
• "Calibration mode", "Level type", "Empty calib.", "Full calib.", "Empty pressure" and "Full
pressure" are parameter names that are used for the local display or remote control,
such as FieldCare.

WARNING
Changing the measuring mode affects the span (URV)
This situation can result in product overflow.
‣
If the measuring mode is changed, the setting for the span (URV) must be checked and
readjusted if necessary.
Perform position adjustment (see information at the start of "Commissioning" section.)
1 Device is installed. Process pressure is not present.
2  Press key for at least 3 s.
3 Does the LED on the electronic insert light up briefly?
4 Yes No
5 Applied pressure for position adjustment has been
accepted.
Applied pressure for position adjustment has not been
accepted. Observe the input limits.
Set the lower pressure value.
1 Desired pressure for lower pressure value ("Empty pressure") is present at the device.
2  Press key for at least 3 s.
3 Does the LED on the electronic insert light up briefly?
4 Yes No
5 Applied pressure was saved as the lower pressure value
("Empty pressure") and assigned to the lower level value
("Empty calib.").
The pressure present was not saved as the lower
pressure value. Observe the input limits.
