The temperature and pressure displayed in gas properties are read from
the internal sheath flow temperature and pressure sensors. The Mean Free
Path and Gas Viscosity are calculated using these measurements based
on default gas properties for air. To manually override the internal
measurements of the classifier, or to edit the gas properties, follow these
instructions:
1. Touch the Gas tab on the Properties screen. The temperature and
pressure are updated every second unless Manual Input is selected.

120 kPa.
