UDU(=)
Purpose Read or set the user definable pressure unit.
Syntax “UDU”
“UDU=text, coef”
Arguments text: The text to use to identify the unit. It can be up to
4 characters wide. This will be the text used to
specify the unit if selecting it remotely, and that
appears on the molbox RFM.
coef: The coefficient to convert Pascal [Pa] to the user
unit. The pressure (in Pa) will be multiplied by this
coefficient before being displayed.
Defaults “UDU=UNIT, 1”
Example Command:
Reply:
“UDU=Bar2, .00001”
“Bar2, 0.000010”
Errors ERR# 2:
ERR# 6:
The text argument is longer than 4 characters.
The coef argument is invalid.
See Also 3.3.2, “PUNIT”
USERCAL(=)
Purpose Read or set the user flow measurement adjustment.
Syntax “USERCAL=adder, mult”
“USERCAL”
Defaults “USERCAL=0, 1”
Arguments adder: The flow adder in the current flow unit and gas
type (0 to FS).
Mult: The flow multiplier (0.1 to 2).
Remarks The user definable adjustment lets the user modify the measured
flow. The adder and multiplier are separated by a comma. The
adder is in the current flow unit.
Example Command:
Reply:
“USERCAL=.58,.995”
“0.58 sccm, 0.995000”
Errors ERR# 6: The adder or multiplier argument is invalid.

UTEMP
Purpose Read or set the temperature reference used for the volumetrically
based mass flow unit with user defined reference temperature.
Syntax “UTEMP=temp”
“UTEMP”
Defaults
“UTEMP=0” (°C)
Arguments temp: The reference temperature in the current
temperature unit of measure.
Remarks This temperature reference is used by the user defined units.
Example Command:
Reply:
“UTEMP=20”
“20.00 C”
