4. Enter the appropriate value in each parameter or select the appropriate option. These
values are written directly to the device.
5. Click "Next" to go to the next page.
6. Once all the pages have been completed, click "End" to close the
Commissioning wizard.
If the Commissioning wizard is cancelled before all the necessary parameters have been
configured, the device may be in an undefined state. In such situations, it is advisable to
reset the device to the factory default settings.
Example: Outputting of the pressure value at the current output
Pressure and temperature units are converted automatically. Other units are not
converted.
In the following example, the pressure value should be measured in a tank and output on the
current output. The maximum pressure of 450 mbar (6.75 psi) corresponds to the 20 mA
current. The 4 mA current corresponds to a pressure of 50 mbar (0.75 psi).
Prerequisites:
• Measured variable in direct proportion to the pressure
• Due to the orientation of the device, there may be pressure shifts in the measured value
(when the vessel is empty or partly filled, the measured value is not zero)
Perform a position adjustment if necessary
• In the Assign PV parameter, the Pressure option must be selected (factory setting)
Display: In the Guidance menu Commissioning wizard, keep pressing the  key until you
reach the Assign PV parameter. Press the  key to confirm, select the Pressure option and
press  to confirm.
