5.1 Transport
Check the instrument for any damage that may have been caused by transport. Obvious
damage must be reported immediately.
Shocks can cause small bubbles to form in the fill fluid of filled instruments.
This has no effect on the function of the instrument.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in
installation site, sending for repair).
5.3 Storage
Permissible storage temperature
-20 ... +70 °C (optional: -40 … +70 °C)
6. Commissioning, operation
6.1 Mechanical connection
In accordance with the general technical regulations for pressure gauges (e.g. EN 837-2
“Selection and installation recommendations for pressure gauges”).
Instruments must be grounded via the process connection.
This is why electrically conductive sealing should be used at the process connection.
Alternatively, take other measures for grounding. When screwing the instruments in, the force
required for sealing must not be applied through the case, but only through the spanner flats
provided for this purpose, and using a suitable tool.
