2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate pressure gauge
has been selected in terms of measuring range, design and specic measuring conditions.
The compatibility of the materials under pressure with the medium must be checked!
In order to guarantee the measuring accuracy and long-term stability specied, the correspond-
ing load limits must be observed.
Non-observance can result in serious injury and/or damage to equipment.
Further important safety instructions can be found in the individual chapters of these operating
instructions.
