9.4.2 Displaying level value as %
With the combination of Full calibration and Empty calibration and with an output signal
of 4 to 20 mA, the level value for 4 mA (=empty) and the level value for 20 mA (=full) can
be determined directly in the unit of length used.
A standardized signal that is proportionate to the level, e.g. 0 to 100 % level, can be
calculated with Full calibration. In turn, the two basic values of 0 % and 100 % can be
assigned directly to the analog output values 4 mA and 20 mA.
X Level Y Output signal as %
X1 0.00 m (0.00 ft) Y1 0 %
X2 Value F (=Full) Y2 100 %
Configuration using DeviceCare or FieldCare
1. Navigate to: Setup → Advanced setup → Linearization type
 Select table as the linearization type
2. Select linearization table
3. X1 = Specify level value in m / ft for 0 %
4. X2 = Specify level value in m / ft for 100 %
5. Confirm table as the linearization type
Configuration with SmartBlue
1. Navigate to: Main menu → Setup → Advanced setup → Linearization type
 Select table as the linearization type
2. Select linearization table
3. X1 = Specify level value in m / ft for 0 %
4. X2 = Specify level value in m / ft for 100 %
5. Activate linearization table
9.5 Data access - Security
9.5.1 Software locking via access code in FieldCare / DeviceCare
The configuration data can be write-protected using an access code (software locking)
‣
Navigate to: Setup → Advanced setup → Administration → Define access code →
Confirm access code
You must enter an access code that is different from the last access code and "0000"
• The access code is only active if a different (wrong) code is entered or the device is
deenergized.
• Once the access code has been defined, write-protected devices can only be switched
to maintenance mode if the access code is entered in the Enter access code
parameter. If the factory setting is not changed or if "0000" is entered, the device is
in maintenance mode and its configuration data are therefore not write-protected
and can be changed at any time.
