PCAL:IH and PCAL:IL
Purpose Read or set the Q-RPT or utility sensor calibration information for the “IH” (internal high) and
“IL” (internal low) RPTs. “IH” is equivalent to “IuH”.
Command
Query
“PCAL:IH adder, mult, CalDate, (GaOnly)”
“PCAL:IL adder, mult, CalDate, (GaOnly)”
“PCAL:IH?”
“PCAL:IL?”
Classic “PCAL:IH =adder, mult, CalDate, (GaOnly)”
“PCAL:IL =adder, mult, CalDate, (GaOnly}”
“PCAL:IH”
“PCAL:IL”
Defaults “PCAL:IH = 0.0, 1.0, 19800101, 0”
“PCAL:IL = 0.0, 1.0, 19800101, 0”
Arguments Adder: The RPT calibration adder (PA). In Pascal.
Mult: The RPT calibration multiplier (PM) from 0.1 to 100.
CalDate: The date of the calibration in the format “YYYYMMDD” by default. The format
“YYMMDD” is also be accepted, and the replied format is in the previously
entered format.
GaOnly Optional “Gauge only” flag. Indicates that the an Axxx Q-RPT is set to
operate in gauge measurement mode only. This field does not apply and is
ignored for Gxxx and BGxxx Q-RPTs or utility sensors.
‘0’ Absolute, negative gauge and gauge modes are available.
‘1’ Gauge mode only.
Remarks The user defined pressure calibration information for the specified RPT (HI or IL pressure)
can be accessed with this program message. Using this program message overwrites the
current calibration coefficients, so caution must be used. If the “GaMode” flag is set and the
RPT is an Axxx Q-RPT, then the RPT will only be allowed to operate in gauge mode.
Changes made using this program message take effect immediately.
The calibration information of DHI RPM4s connected to PPC3 must be adjusted directly on
the RPM4. The information cannot be adjusted through the PPC3.

PR
Purpose Read the next available pressure.
Query “PR?”
Classic “PR”
Remarks The next available pressure value for the active Q-RPT or utility sensor 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 (R or NR). 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 PPC3 replies back with the data after a new pressure
measurement cycle is complete. This can take up to 1.5 seconds.
