The entered bath temperature is outside of the range of temperatures
specified in the Adsorptive Properties.
Change the entered temperature.
Change the adsorptive.
Add more temperatures and corresponding pressures to Adsorptive
Properties.
An attempt was made to start an analysis using a file that contains
errors and is open for editing.
Finish editing this file, save and close it then start the analysis.
The backfill gas specified in the sample information file does not
match the analysis gas entered in the Unit Configuration.
If the wrong backfill gas was selected in the sample information file,
change the backfill gas in the file.
If necessary, attach the appropriate gas bottle, then enter the gas in the
Unit Configuration.
Less than two selected data points are within the fitted pressure range.
Edit the calculation assignments on the Collected Data window or
change the fitted pressure range on the Dubinin report options
window.
Less than two of the selected sample files for heat of adsorption
reports contain appropriate data.
Edit the Quantity Adsorbed table or select other sample files.
