)
or
Absolute Pressure (mmHg) -
the pressure
the equilibration interval will be applied.
•
Equilibration Interval -
the number of seconds between successive
pressure readings during equilibration. At least 11 pressure readings for
each equilibration are required to obtain an accurate reading of the
pressure changes.
Long equilibration intervals tend to lengthen analyses, but improve data
integrity.
Short equilibration intervals produce a faster analysis but may reduce
the accuracy of data.
•
Minimum equilibration delay at p/p
o
> =0.995
- the minimum number
of seconds required before equilibration can occur for a relative pressure
greater than or equal to 0.995. This field is not available if
Absolute
pressure dosing
is selected on the
