In the case of a temperature change the
instrument requires at least 30 minutes to
adjust to the new ambient temperature.
3.2
Pneumatic connections
Before making the pneumatic connection to
the instrument, ensure that no pressures can
occur in the system which could exceed the
maximum overload capacity of the HM22. The
connections are intended for direct connection
to the measuring pipelines (hose, internal
diameter
4
mm,
6 mm). The 0...1/10 bar measuring range is
always fitted with NPT 1/8" connection unions.
Ensure correct connection of the pneumatic
hoses!
