Checking the airflow

Optional:
To ensure that the system is functioning correctly, check that
the air speed enables a sufficient differential pressure to be set
in the device. This can be done by using a manometer. The air
speed in the duct should read between 1.5 m/s and 20 m/s.
The differential pressure between the sample tubes must
measure within the following range:
