4017- Damage to the instrument will result if the sample has not been manually evac-
uated. Have you evacuated the sample?
Cause: You did not select
Backfill sample at start of analysis
on the Sample
Backfill Options dialog box. The sample tube is normally at atmo-
spheric pressure when an analysis is started, and it must be backfilled
before the analysis begins to prevent sample material from being
drawn into the manifold.
Action: If you have manually evacuated the sample tube, select
Yes
. If you
have not, select
No
and then either perform a manual evacuation or go
to the Sample Backfill Options dialog box and select
Backfill sample
at start of analysis
.
4020- Disabling this option may damage the instrument. Are you sure that the sample
should not be backfilled?
Cause: You did not select
Backfill sample at start of analysis
on the Sample
Backfill Options dialog. The sample tube is normally at atmospheric
pressure when an analysis is started; it must be backfilled before the
analysis begins to prevent sample material from being drawn into the
manifold.
Action: If you want to manually evacuate the sample prior to the start of the
analysis, select
Yes
. Otherwise, select
No
, go to the Sample Backfill
Options dialog, and select
Backfill sample
at start of analysis.
4021- The entered Po value (Po and Temperature Options of the Analysis Conditions)
is outside the range of the pressures listed in the Psat vs. Temperature Table (Adsorp-
tive Properties).
Cause: The temperature that corresponds to the entered Po cannot be found
because the entered Po is outside of the range of values in the Psat vs. T
table.
Action A: Enter a Po that is within the range of the table.
Action B: Use a different Psat vs. T table.
