Pressure in Microns
Time in Minutes
Continously increasing pressure
indicates the presence of leaks,
moisture, or both.
Initial evacuation pressure.
State of equilibrium indicates the
true amount of moisture left in
the system. It indicates that no
leaks are present and the system
is properly evacuated.
State of equilibrium indicates the
true amount of moisture left in
the system. It indicates that no
leaks, but requires further evacuation.
