CALx(=)
Purpose
To set or read the calibration adder and multiplier for PG7000 Platform internal measurement
sensors.
Syntax “CALx=adder,
mult”
“CALx”
Default CALx=0,
1
Argument
x:
“1” for the piston temperature sensor (degrees Celsius).
“2” for the ambient temperature sensor (degrees Celsius).
“3” for the ambient pressure sensor (Paa).
“4” for the vacuum sensor (Paa).
“5” 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 default value or a user defined value.
Example Typical
command:
Typical reply:
“CAL2=100.0, 1”
“100.0 Paa, 1.000000”

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=2400,E,7,1”
“COM3=2400,E,7,1”
Argument
x:
“1” for COM1 port
“2” for COM2 port
“3” for COM3 port
The arguments must be separated by commas.
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 gage.
COM3 is used for control of an external PPC pressure controller and/or an AMH automated
mass handler.
Serial Parameters:
Baud rates:
150 300 600 1 200 2 400 4 800 9 600
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

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 1980 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“19991231
”=19991231”
Error
