PRR
Purpose
Read the next available Ready condition, pressure measurement, rate and on-board
barometer reading.
Query “PRR?”
Classic “PRR”
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
next
available
Ready condition, Q-RPT pressure measurement, rate of pressure change,
and barometric pressure is replied in the current pressure unit of measure. . This can take up
to the current read rate period (1.2 seconds by default). Each data field is separated by a
comma, and is returned in the following order:
ready, pressure UNITS, rate UNITS/s, atm UNITS
Here are the field descriptions:
ready:
Three character ready status field. Refer to the “SR” command.
pressure:
The measured pressure for the active Q-RPT in the current pressure unit.
This is followed by the current pressure unit.
rate:
The measured rate of pressure change for the active Q-RPT in the current
pressure unit per second. This is followed by the current pressure unit of measure.
atm:
The pressure measured by the RPM4 on-board barometer in the current
pressure unit (and always absolute). This is followed by the current pressure
unit. Not all RPM4s are equipped with an on-board barometer. This field is
missing if the RPM4 is not equipped with an on-board barometer.

QPRR
Purpose
Read the last Q-RPT pressure measurement, pressure rate and on-board barometer output
immediately.
Query “QPRR?”
Classic “QPRR”
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 last measured Ready/Not Ready condition, active Q-RPT pressure measurement, rate of
pressure change, and barometric pressure is replied in the current pressure unit of measure
immediately. This program message is useful when a rapid response of measured pressure
is needed. It does not result in quicker pressure measurements. Each data field is separated
by a comma, and is returned in the following order:
Ready, pressure UNITS, rate UNITS/s, atm UNITS
Here are the field descriptions:
ready:
Three character ready status field. Refer to the “SR” command.
pressure:
The measured pressure for the selected Q-RPT in the current pressure unit.
This is followed by the current pressure unit and measurement mode.
rate:
The measured rate of pressure change for the active Q-RPT in the current
unit of pressure per second. This is followed by the current pressure unit.
atm:
The pressure measured by the RPM4 on-board barometer in the current
pressure unit (but always absolute). This is followed by the current pressure
unit. Not all RPM4s are equipped with an on-board barometer. This field is
missing if the RPM4 is not equipped with a barometer.
