Description
Pressure table
Selects the means for changing or preserving the currently stored tar-
get relative pressure table.
Choices are:
Replace, Preserve, Edit
The highest adsorption point prior to saturation should
be 0.9990 P/Po. If saturation pressure has decreased
significantly since the previous measurement, target
pressures close to 1.0 P/Po can result in premature sat-
uration.
Replace
Replaces the currently stored pressure table with a new table of
evenly spaced points.
Enter the
First rel. pressure
for data collection.
Range:
0.00001
to
1.0000 P/Po
Enter the
Last rel. pressure
for data collections.
Range:
First rel. pressure to 1.0000 P/Po
Enter the same value entered for
First rel. pressure
if performing a
single-point analysis. The analyzer collects the specified number of
data points at evenly spaced pressure intervals during the period of
analysis. Enter 1 if performing a single-point analysis.
