TriStar II 3020 Appendix B
302-42828-01 - Dec 2013 B-17
4022- The entered bath temperature value (Po and Temperature Options of the Anal-
ysis Conditions) is outside the range of the temperatures listed in the Psat vs
Temperature Table (Adsorptive Properties).
4023- The file [file name] cannot be prepared for analysis. It is open for editing and
contains errors.
4024- Backfill gas in sample file does not match any gas in the unit.
4026- Cannot calculate Dubinin-Astkahov: bad least squares data.
4027- Fewer than two sample files have data suitable for heat of adsorption reports.
Cause: The entered bath temperature is outside of the range of temperatures
specified in the Adsorptive Properties.
Action A: Change the entered temperature.
Action B: Change the adsorptive.
Action C: Add more temperatures and corresponding pressures to Adsorptive
Properties.
Cause: An attempt was made to start an analysis using a file that contains
errors and is open for editing.
Action: Finish editing this file, save and close it then start the analysis.
Cause: The backfill gas specified in the sample information file does not
match the analysis gas entered in the Unit Configuration.
Action A: If the wrong backfill gas was selected in the sample information file,
change the backfill gas in the file.
Action B: If necessary, attach the appropriate gas bottle, then enter the gas in the
Unit Configuration.
Cause: Less than two selected data points are within the fitted pressure range.
Action: Edit the calculation assignments on the Collected Data window or
change the fitted pressure range on the Dubinin report options
window.
Cause: Less than two of the selected sample files for heat of adsorption
reports contain appropriate data.
Action: Edit the Quantity Adsorbed table or select other sample files.
