Leak test duration. Enter the duration of the leak test.
Unrestricted evac. from. The pressure at which unrestricted
evacuation is to begin. This option is enabled when Fast evacuation
is not selected.
Use TranSeal. Select if using the TranSeal to transfer the sample
from the preparation port to the analysis port under vacuum.
Available when the Target Pressures option is selected. Use to edit
the Entered Pressures table.
The pressure table consists of relative pressure points at which
isotherm data are to be collected. An optional pressure increment
can be entered in the Pressure Increment column, which will cause
additional points to be collected at intervals of the pressure
increments up to the relative pressure specified in the Ending
Pressure column.
The relative pressure points may span the entire range of
0.000000000 to 0.000000001 p/p
branch (strictly increasing pressures) followed optionally by one
desorption branch (strictly decreasing pressures).
