An absolute pressure greater than (pressure) mmHg was attained dur-
ing Low pressure dosing (either fixed dose mode or incremental dose
mode).
The analysis was canceled. All previously collected data were stored.

to leaks in the system.
Perform leak checks on the system. Refer to Appendix E, Testing for
Leaks.
The value for the Po may be too low, causing the instrument to mistake
condensation for actual adsorption.
Change the analysis variables to directly measure the value of Po dur-
ing the experiment.
The amount of sample you used may be too large. Multiply the max-
imum value from the Volume Adsorbed column of the Isotherm Report
by the sample weight. If the result exceeds (volume) cm
of sample is too large.
Reduce the amount of sample.
An absolute pressure greater than (pressure) mmHg was attained that
exceeded the specified maximum manifold pressure.
The analysis was canceled. All previously collected data were stored.
Change the maximum manifold pressure value in the Adsorptive Prop-
erties file.
