2.8 Test
pressure
Each instrument is pressure tested.
The tested pressure is stated on the instrument label.
The absolute maximum line pressure is 10 bar (g). Check test pressure before installing in the line. If the
label is not available or the test pressure is incorrect, the instrument should not be mounted in the
process line.
2.9 Supply
pressure
Do not apply pressure until electrical connections are made. When applying pressure to the system, take
care to avoid pressure shocks in the system and increase pressure gradually.
To use both the power supply and an analog or digital connection, you should use the optional
shielded RJ‐45 Y‐adapter.
