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..

3.4.3
TIME
Purpose Read or set the RPM4 internal clock.
Command
Query “TIME hh:mmXX”
“TIME?”
Classic “TIME=hh:mmXX”
“TIME”
Arguments hh:mm:
XX: The time in a 12 hour format using a colon delimiter
”am” or “pm”
Example
(enhanced) Cmd sent:
Query reply: “TIME 12:52PM”
“12:52pm” (No reply if GPIB-488)
Example
(enhanced) Cmd sent:
Query reply: “TIME? 12:52PM”
“12:52pm”
Example
(classic) Sent:
Reply: “TIME=12:52PM”
“12:52pm”
Errors ERR# 7: Missing or improper program message argument(s).
See Also “DATE”
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
