At this time, the flow rate of the purge gas is measured by the mass flow meters 3f and 4f while controlling the flow rate by the mass flow controllers 3a and 4a. Then, verification is performed by comparing the flow rates measured by the mass flow meters 3f and 4f with the set flow rates of the mass flow controllers 3a and 4a.

- the on-off valve 10 After evacuating the space to a predetermined reduced-pressure atmosphere by the vacuum exhaust pump 5, the on-off valve 10 is closed and the inside of the no-pass pipe 8 is sealed. Next, the opening / closing valve 3b is opened, the processing gas is flowed while controlling the flow rate by the mass flow controller 3a, and the relationship between the pressure rise and the elapsed time by the pressure gauge 9 at this time is measured. Then, after using for a predetermined period, the same measurement is performed, and the mass flow controller 3a tests the normal force / non-force based on the amount of deviation from the initial time. This method is generally called build-up method
