PCALDATE(=)
Purpose
Read or set the user RPT calibration dates.
Syntax
“PCALDATE=yyyymmdd, yyyymmdd”
“PCALDATE”
Defaults
“PCALDATE=19980101,19980101
Arguments
yyyy:
mm:
dd:
The year from 1980 to 2079.
The month from 1 to 12.
The day from 1 to the last valid day of the given month.
Remarks
The user defined pressure calibration dates for the upstream and downstream
RPTs can be access with this single command in this order.
Example
Command:
Reply:
“PCALDATE=19981005, 19981005”
“19981005, 19981005”
Errors
ERR# 7:
One or more of the date(s) are invalid.

5.2, “PCAL(=)”
PCOEF
Purpose
Read the coefficient to convert Pascal [Pa] to the current pressure units.
Syntax
“PR”
Remarks
The pressure coefficient (PCOEF) is a value that is used to convert Pascal units
to the current pressure units. To use this coefficient, multiply it by pressure in
Pascal to get pressure in the current units.
Example
Command:
Reply:
“PCOEF”
“1.000000e-003”

3.5.8, 7.1.1, “PUNIT”
PR
Purpose
Read the next molbloc average pressure.
Syntax
“PR”
Remarks
The next available average
upstream downstream
−
2
pressure value is read in
the current pressure units. It is the average of the
tare
corrected upstream and
the downstream transducers. The data string also contains flow ready
information, and the pressure units.
The first 3 characters of the reply are reserved for the flow
ReadyNot Ready
status.
The
Ready/Not Ready
status is covered in the “SR” command. The pressure
measurement number starts at the fifth character, and is followed by the pressure
unit of measure.
Example
Command:
Reply:
“PR”
“R 247.5982 kPa a”

“READYCK”, “SR”, “DP”, “PRHI”, “PRLO”. “ALLR”
PRHI
Purpose
Read the last measured upstream absolute pressure (
tare
corrected).
Syntax
“PRHI”
Remarks
The current upstream pressure value (corrected for
tare
) is returned in the current
pressure unit of measure.
Example
Command:
Reply:
“PRHI”
“247.56 kPaa”
See Also
“DP”, “PR”, “PRLO” . “ALLR”
PRLO
Purpose
Read the last measured downstream absolute pressure (
tare
corrected).
Syntax
“PRLO”
Remarks
The current downstream pressure value (corrected for
tare
) is returned in the
current pressure unit of measure.
Example
Command:
Reply:
“PRLO”
“224.67 kPaa”
See Also
“DP”, “PR”, “PRHI” . “ALLR”
PUNIT(=)
Purpose
Read or set the pressure display unit of measure.
Syntax
“PUNIT=unit”
Defaults
“PUNIT”
Arguments
unit:
The text corresponding to the pressure unit of measure. The
pressure unit protocol is the same as the protocol used for front
panel entries and displays.
Remarks
This command determines what unit of measure is used to display pressure.
Example
Command:
Reply:
“PUNIT=KPA”
“kPa a”
Errors
ERR# 7:
The unit is invalid.
