ordering)
• DIP switch to Off position
• If Bluetooth is ordered, then Bluetooth is switched on
8.2 Function check
Perform a function check before putting the measuring point into operation:
• "Post-installation check" checklist (see the "Installation" section)

The following functions are possible via the keys on the electronic insert:
• Position adjustment (zero point correction)
The orientation of the device may cause a pressure shift
This pressure shift can be corrected by a position adjustment
• Setting the lower range value and upper range value
The pressure applied must be within the nominal pressure limits of the sensor (see the
specifications on the nameplate)
• Resetting the device
Carrying out position adjustment
1. Device installed in desired position and no pressure applied.
2. Press the "Zero" and "Span" keys simultaneously for at least 3 s.
3. When the LED lights up briefly, the pressure present has been accepted for position
adjustment.
Setting the lower range value (pressure or scaled variable)
1. The desired pressure for the lower range value is present at the device.
2. Press the "Zero" key for at least 3 s.
