mbar during a degas command. The bit is reset if the pressure value
drops below 7.2
×10 -6 mbar.
The Sensor Warning bits defined here are copied into the Device Block ID 28 in the
"Device Exception Detail Warning" range of the BA measuring part.
Byte 0 of Sensor Alarm and Sensor Warning represents the filament status of the
