CALx(=)
Purpose To set or read the calibration adder and multiplier for PG9000 Platform internal measurement
sensors.
Syntax “CALx=adder, mult”
“CALx”
Default CALx=0, 1
Argument x: “1” for the ambient temperature sensor (degrees Celsius).
“2” for the ambient pressure sensor (Paa).
“3” for the vacuum sensor (Paa).
“4” for the relative humidity sensor (%RH).
adder: The calibration adder.
mult: The calibration multiplier.
Remarks The internal sensors can be calibrated by the user if needed. This is possible by specifying
an adder or a multiplier, or both if needed.
The ambient sensor measurement is adjusted using the user calibration adder and multiplier:
Adjusted Ambient measurement = (measurement x multiplier) + adder
This calibration information should be changed with care, as it affects the ambient value. It
does not affect the normal value or a user defined value.
Use the PRTPC n command to access the piston cylinder temperature PRT calibration(s).
Example Typical command:
Typical reply: “CAL2=100.0, 1”
“100.0 Paa, 1.000000”
Error See Section 4.3.3 Error Messages

COMx(=)
Purpose To set or retrieve the configuration of the COM ports.
Syntax “COMx=baud,parity,data,stop”
“COMx”
Default “COM1=2400,E,7,1”
“COM2=9600,N,8,1”
“COM3=2400,E,7,1”
“COM4=2400,E,7,1”
Argument x: “1” for COM1 port
“2” for COM2 port
“3” for COM3 port
“4” for COM4 port
Remarks The available parameters are listed below. Once the port is configured, the configuration is
stored in permanent memory and becomes active on power up.
When the configuration of the primary port (COM1) is changed, the returned reply is sent at the
original COM1 settings but all subsequent replies will be sent at the new configuration settings.
COM2 is used for an external barometer and/or external vacuum gauge.
COM3 is used for control of an external PPC pressure controller. COM4 is used for general
purpose device communications using the PASSTHRU command.
Serial Parameters:
Baud rates: 300,1200,2400,4800,9600,19200, 28800, 38400
Parity: O – Odd, E – Even, N – None
Data bits: 7 8
Stop bits: 1 2
Example Typical command:
Typical reply: “COM1=9600,E,7,1”
“9600,E,7,1”
Error See Section 4.3.3 Error Messages
ERR #1 Missing or wrong COM setting
See Also 3.12.5, “PASSTHRU”
DATE(=)
Purpose To read or set the internal calendar.
Syntax “DATE=YYYYMMDD”
“DATE”
Default N/A
Argument The date in the YYYYMMDD format.
YYYY: The year from 2000 to 2079.
MM: The month 1 to 12.
DD: The day of the month 1 to (up to) 31 depending on the month
and year.
Remarks The internal calendar is used to date stamp changes made to the internal sensor
calibrations and the piston-cylinder module, mass set and mass loading bell files.
Example Typical command:
Typical reply: “DATE=20031025”
” 20031025”
Error See Section 4.3.3 Error Messages
ERR #1 If invalid date argument
