8 Commissioning
If an existing configuration is changed, measuring operation continues! The new or
modified entries are only accepted once the setting has been made.
L
WARNING
Risk of injury from the uncontrolled activation of processes!
‣
Make sure that downstream processes are not started unintentionally.

• Configuration of pressure measurement → 27
• If necessary, perform position adjustment → 29
• If necessary, Configuration of process monitoring if necessary → 32
• If necessary, Configuration of the local display if necessary → 37
• If necessary, Protection of settings from unauthorized access if necessary → 38
8.4 Configuring pressure measurement (only for devices
with a current output)
8.4.1 Calibration without reference pressure (dry calibration =
calibration without medium)
Example:
In this example, a device with a 400 mbar (6 psi) sensor is configured for the measuring
range 0 to 300 mbar (0 to 4.4 psi).
The following values should be assigned:
• 0 mbar = 4 mA value
• 300 mbar (4.4 psi) = 20 mA value
