PCALn
Purpose
Read or set the calibration information for the Hi or Lo Q-RPT.
Command
Query
“PCALn adder, mult, CalDate”
“PCALn?”
Classic “PCALn= adder, mult, CalDate”
“PCALn”
Defaults “PCALn = 0.0, 1.0, 19800101”
“n”
The active Q-RPT is assumed if no suffix is given. The Hi Q-RPT is assumed if the HL
Q-RPT is active and no suffix is given.
‘1’ Specify the Hi Q-RPT
Optional Suffix
‘2’ Specify the Lo Q-RPT
Arguments
Adder:
The Q-RPT calibration adder (PA). In Pascal.
Mult:
The Q-RPT calibration multiplier (PM) from 0.1 to 100.
CalDate:
The date of the calibration in the format “YYYYMMDD” by default. Any other
format up to 8 characters long is also accepted, and the replied format is in th
previously entered format.
Remarks
The user defined pressure calibration information for the specified Q-RPT (Hi or Lo) can be
accessed with this program message. The HL Q-RPT does not have it’s own calibration
information. Using this program message overwrites the current calibration coefficients, so caution
must be used. Changes made using this program message take effect immediately.
For compatibility with the obsolete style PPC3 “PCAL:HI” and “PCAL:LO” commands, “:HI” and
“:LO” can be used in place of the suffix “n” but this is not recommended for new applications.

PRn
Purpose
Read the next available pressure measurement.
Query “PRn?”
Classic “PRn”
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 pressure value for the specified or active Q-RPT is read in the current pressure
units. The data returned also contains Ready/Not Ready information, and the pressure unit of
measure and measurement mode.
The reply field is always 20 characters long. The first 3 characters of the reply are reserved for the
ready status. The ready status is described in the “SR” program message. The pressure value and
pressure unit of measure are right justified in this field.
After receiving this program message, the RPM4 replies back with the data after a new pressure
measurement cycle is complete. This can take up to the current read rate period (1.2 seconds by
default).
