When entering an operation pressure <30 mbar calculations will be
made based on the reference operation pressure 23 mbar.
When entering an operation pressure > 30 mbar calculations will be
made using the inserted operation pressure.
Medium is the gas in the pipe being used during the test. Methane and
air are available for selection. It is important to select the right medium
because Methane can evacuate more easily through a leakage than
air!
The test result is always based on Methane.
With F2 the values will be set back to the default values in the chart
above.

Apply test pressure
In this screen you will apply pressure to the pipe that will be tested. If
the pressure is below 20 mbar the pressure bar will be red and the
MFplus will display an error message when the test is started.
