8.6.2 Calibration with reference pressure (wet calibration)
Example:
In this example, a device with a 400 mbar (6 psi) sensor module is configured for the
0 to +300 mbar (0 to 4.5 psi) measuring range, i.e. the 4 mA value and 20 mA value are
assigned 0 mbar and 300 mbar (4.5 psi) respectively.
Prerequisite:
The pressure values 0 mbar and 300 mbar (4.5 psi) can be specified. For example, the
device is already installed.
For a description of the parameters mentioned, see .

2 Select the "Pressure" measuring mode via the "Measuring mode" parameter.
Menu path: Setup → Measuring mode

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 in
the "Setup" operating menu and readjusted if necessary.
3 Select a pressure unit via the "Press. eng. unit" parameter, here "mbar" for example.
Menu path: Setup → Press. eng. unit
4 The pressure for the LRV (4 mA value) is present at the device, here 0 mbar for example
Select the "Get LRV" parameter.
Menu path: Setup → Extended setup → Current output → Get LRV
Confirm the value present at the device by selecting "Apply". The pressure value present at
the device is assigned to the lower current value (4 mA).
5 The pressure for the URV (20 mA value) is present at the device, here 300 mbar (4.5 psi)
for example.
Select the "Get URV" parameter.
Menu path: Setup → Extended setup → Current output → Get URV
Confirm the value present at the device by selecting "Apply". The pressure value present at
the device is assigned to the upper current value (20 mA).
6 Result:
The measuring range is configured for 0 to +300 mbar (0 to 4.5 psi).
8.7 Backing up or duplicating the device data
The device does not have a memory module. However, with an FDT technology-based
operating tool (e.g. FieldCare) you can do the following:
• Save/recover configuration data
• Duplicate device configurations
• Transfer all relevant parameters when replacing electronic inserts
• The mechanism is based on IO-Link Data Storage
For more information, read the operating manual for the FieldCare operating program.
