ERR
Purpose Read the last error message.
Syntax “ERR”

has occurred. If the user receives an “ERR# nn” reply, the
“ERR” command returns a brief description about the last error
number that was replied.
Example Command:
Reply:
“ERR”
“Missing or improper command argument(s)”
See Also 4.3.3
FA=
Purpose Start a single flow averaging cycle.
Syntax “FA=period”
Arguments period: The averaging period in seconds (from 4 to 999
seconds).
Remarks This command is used to start an averaging period that results
in the average molbloc flow and standard deviation of the
molbloc flow over this period. After sending this command you
can monitor the averaging cycle by using the “FR” or “SR”
command to determine when the averaging cycle is complete.
Once the cycle is done, you must use the “FRA” command to
collect the results.
Example Command:
Reply:
“FA=20”
“20 s”
Errors ERR# 6: The period argument is not within the specified
limits.
See Also 3.2.6.2, “FR”, “SR”, “FRA”, “ABORT”
FCOEF
Purpose Read the coefficient that converts kg/s to the current flow units.
Syntax “FCOEF”
Remarks The flow coefficient is a value that is used to convert kg/s to the
current flow units. It is dependent on the current flow unit and
the gas selected. To use this coefficient, multiply it by kg/s to
get flow in the current flow units.
Example Command:
Reply:
“FCOEF”
