Prior to commissioning, the digital pressure gauge must be subjected to a visual inspection.
Only use the digital pressure gauge if it is in perfect condition with respect to safety.
Required tool: Open-ended spanner (spanner width 27)
6.1 Mechanical mounting
The sealing faces at the instrument have to be
■
undamaged and clean.
When screwing the instrument in, the force
■
required to do this must not be applied through
the case, but only through the spanner flats
provided for this purpose and using a suitable
tool.
The correct torque depends on the dimensions
of the process connection and the gasket used
(form/material).
Do not overwind the process connection, do not exceed the permissible torques.
When screwing in, do not cross the threads.
