8.  Turn on the pipeline air source and record the reading on the test pressure gauge. If the 
difference between the readings of the test pressure gauge and pipeline air pressure 
gauge exceeds 0.1 MPa (1.0 bar), the pipeline air pressure gauge is damaged. Handle 
this problem according to the fault identification table.   
9.  Reconnect PU tube 41 to the pressure gauge.
