Requirement
All shut-off valves are closed.
Procedure
To commission the pressure transmitter for gases, proceed as follows:
1. Open both the shut-off valves ⑥ at the pressure tapping point.
2. Open the stabilizing valve
②.
3. Open the differential pressure valve (
③ or ④).
4. Check and, if necessary, correct the zero point when the start-of-scale value is 0 kPa (4 mA).
5. Close the stabilizing valve
②.
