Note
Hot surfaces
Hot process medium and high ambient temperatures lead to hot surfaces which can cause
burns.
• Take corresponding protective measures, for example wear protective gloves.
8.2 Introduction to commissioning
Following commissioning, the pressure transmitter is immediately ready for use.
To obtain stable measured values, the pressure transmitter needs to be allowed to warm up
for five minutes or so after the power supply is switched on.
The operating data must correspond to the values specified on the nameplate. If you switch
on the auxiliary power, the pressure transmitter will operate.
The following commissioning cases are typical examples. Configurations different from those
listed here may be meaningful depending on the system configuration.

WARNING
Incorrect or improper operation
If the lock screws are missing or are not sufficiently tight, and/or if the valves are operated
incorrectly or improperly, it could lead to serious physical injuries or considerable damage
to property.
Measure
•
Make sure the locking screw and/or the vent valve are screwed in and tightened.
