Supplement - 17
3.4.2 Control System Calibration by LON-Variables
SYSCAL can also be controlled by LON-Variable CMFUNC. Setting this variable will cause
the appropriate function (see following table).
CMFUNC
function which is started
1
system zero-calibration
2
system zero/span-calibration
3
user defined sequence program
4
cancel a running system calibration
We can also realize some other functionality with setting of LON-Variables.
Herefore see the appropriate menu pages, where the concerned variables are
documentated.
For example: "Test procedures".
SCTESTGAS
SCTIMEOUT
SCCALTIME1
SCSTEPMOD
Here we have first to set variable SCSTEPMOD similar to the TAG of the requested analyzer
module. Setting SCTIMEOUT will set the timeout.
And setting variable SCTESTGAS to the appropriate enum-value will start the procedure.
