Description
Enter the number of data points to be collected.
Range: 1 to 1000
Preserves the currently stored pressure table. No further pressure
table question prompts are displayed.
Allows for viewing and editing of the current pressure table. This is
useful if an unevenly spaced sequence of data points is applicable;
for example, when a five-point surface area is to be combined with a
single-point total pore volume.
Enter the next applicable target relative pressure or accept the
default and press ENTER. Entries must be in ascending order. This
request is made for each pressure in the table or until 1000 points
have been entered. An entry of 0.0000 terminates the table. An entry
of 1.0000 specifies a saturation pressure measurement and
terminates the table. If a saturation pressure measurement is
specified, the stored Po value is updated automatically when the
measurement is made.
Range: 0.0001 plus the previous target pressure to 1.0000
This following prompt displays only for the Gemini VII 2390t. Follow
the instructions given for the Adsorb pressure prompt, except the
entries must be in descending order for desorption.
Range: 0.9999 plus the previous target pressure to 0.0
