Read or set the current pressure stability limit.
"SS limit"
"SS?"
"SS=limit"
"SS"
"n"
The active Q-RPT is assumed if no suffix is given.
'1'
Specify the Hi Q-RPT if the HL RPT is not active
Specify the HL Q-RPT if the HL Q-RPT is active
'2'
Specify the Lo Q-RPT
'3'
Specify the HL Q-RPT if the HL Q-RPT is active
Limit:
The stability limit in the current pressure unit of measure.
The stability limit can be read and set as a pressure. The stability limit is used as the
Ready/Not Ready criteria. It the Q-RPT is in an altitude or airspeed unit, then the stability
setting is represented in the pressure unit "Pa".

To identify the coefficient used to convert 1 Pascal to the current pressure unit of measure.
"UCOEFn Pres"
"UCOEFn Pres, Temp"
"UCOEFn?"
"UCOEFn = Pres, Temp"
"UCOEFn"
Pres:
Pressure in Pa to convert to the Q-RPT's measurement units.
Temp:
Optional reference temperature in °C if the Q-RPT unit is a "True" airspeed.
"n"
The active Q-RPT is assumed if no suffix is given.
'1'
Specify the Hi Q-RPT if the HL RPT is not active
Specify the HL Q-RPT if the HL Q-RPT is active
'2'
Specify the Lo Q-RPT
'3'
Specify the HL Q-RPT if the HL Q-RPT is active
The RPM4-AD handles all pressure values internally in Pascal. The coefficient replied is
equivalent of Pres Pa in the current pressure unit of measure. If the optional argument Pres
is not given, then 1Pa is assumed and converted. The Temp argument is only valid for True
airspeed units.
