Appendix B TriStar II 3020
B-32 302-42828-01 - Dec 2013
6025- Target pressure [PRn] [PR-U] exceeded maximum manifold pressure of [PRn]
[PR-U]. Analysis is canceled.
6026- Psat gas is not condensing.
6027- There is no nitrogen attached to the unit.
6028- The backfill gas in sample file does not match any gas in the unit.
6029- The Po in the sample file does not match any gas in the unit.
Cause: An absolute pressure greater than (pressure) units was attained that
exceeded the specified maximum manifold pressure.
Action: The analysis was canceled. All previously collected data were stored.
Change the maximum manifold pressure value in the Adsorptive
Properties file.
Cause A: The working Dewar does not contain enough bath liquid.
Action A: Refill the Dewar and try the operation again.
Cause B: The Psat gas is contaminated.
Action B: Replace the Psat gas supply.
Cause C: The Psat tubing from the regulator to the instrument is contaminated.
Action C: Pump out the tubing.
Cause: A calibration requiring nitrogen was attempted but the software does
not recognize that nitrogen is attached.
Action: Ensure that a nitrogen gas bottle is installed at one of the analysis
ports, then Select Unit > Unit configuration and enter N2 for the
appropriate valve.
Cause: An attempt was made to start an analysis with a gas that is not
connected to the instrument or has not been designated in the
software.
Action A: Ensure the gas is connected to the instrument. Then select Unit [n] >
Unit configuration to tell the application that the gas is connected.
