5.4.3 Requirement for shielding and grounding
The pressure switch must be grounded via the process connection.
When working during a running process operation, measures to prevent electrostatic discharge on the connection
terminals should be taken, as a discharge could lead to temporary corruption of the measured value.

5.5 Zero point setting
Check the indicated zero point on the digital display during commissioning. Should a zero point offset be displayed as
a result of installation, this can be reset in programming mode or via IO-Link with the 0SET parameter.
Only carry out zero point setting for gauge and vacuum pressure measuring ranges at the start of the measuring range.
Carry out zero point setting of absolute pressure measuring ranges at 0 bar absolute (vacuum). Since
appropriate references are required for this, we recommend that this is only carried out by the manufac-
turer.
