NGA-2000 System Calibration

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".

--Test Procedures --

 

 

 

Gastest of specific module

SAMPLE-Gas

Timeout for Gastest (0 = no timeout)

180 s

Choose specific analyzer module...

 

_______________________________________________

Procedure time:10 s

Analyzer-module:MLT/CH3

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.
