6.4 Vacuum Level and Atmospheric Pressure
The vacuum level provided by the console depends on the local atmospheric pressure, thus on
the altitude. The atmospheric pressure decreases with the altitude.
Up to 2000 meter altitude: 0.75mmHg per 8m; above 2000 meter altitude: 0.75mmHg per 11m
Atmospheric
pressure at sea level
~760 mmHg
Atmospheric
pressure at
3000m above sea
level
~504 mmHg
IMPORTANT NOTE
The system displays relative vacuum. The vacuum depends on the power of the
pump and on local atmospheric pressure. The suction is more efficient at sea
level than above sea level.
