The working Dewar does not contain enough bath liquid.
Retry the operation after filling the Dewar.
The Psat gas is contaminated.
Replace the Psat gas supply.
The Psat tubing from the regulator to the instrument is contaminated.
Pump out the tubing.
Main power failed but UPS (if attached) is working.
Restore power to the analyzer.
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) cm3, the amount
of sample is too large.
Reduce the amount of sample.
