SSn
Purpose Read or set the current pressure stability limit.
Command
Query
“SS limit”
“SS?”
Classic “SS=limit”
“SS”
Optional Suffix
“n”
The active Q-RPT is assumed if no suffix is given.
‘1’ Specify the Hi Q-RPT
‘2’ Specify the Lo Q-RPT
Arguments
Limit:
The stability limit in the current pressure unit of measure.
Remarks The stability limit can be read and set as a pressure. The stability limit is used as the
Ready/Not Ready criteria..

3.5.5.3
UCOEFn
Purpose To identify the coefficient used to convert 1 Pascal to the current pressure unit of measure.
Query “UCOEFn?”
Classic “UCOEFn”
Optional Suffix
“n”
The active Q-RPT is assumed if no suffix is given.
‘1’ Specify the Hi Q-RPT
‘2’ Specify the Lo Q-RPT
Remarks The RPM4 handles all pressure values internally in Pascal. The coefficient replied is
equivalent of 1 Pa in the current pressure unit of measure. This program message allows the
user to convert pressures
