NGA-2000 System Calibration
90003482(2) [NGA-e (MLT-Software 3.2.X)] 07/98 NGA 2000 Supplement - 7
3.1 Set-up analyzer modules
Before we can run any system calibration features we have to include the different analyzer
modules (AM’s) into system calibration by setup needed parameters. Only after correct
setting up, an AM is included into system calibration and only then it makes sense to go into
the other menus.
SCAMGAS
SCVALVE
SCPURGE
SCMODULE
SCCONTROL
Setting up an AM for system calibration means assigning valves from system valve pool.
The Control Module provides support of up to 32 system-valves V1....V32. We have to
decide which valves deliver which gases for an analyzer module. Also we have to know the
purge time from a valve to the AM/ MLT channel.
For each of the following types in the parameter „Gas type“ we have to assign a valve and
the appropriate purge time :
• SAMPLE-GAS
• ZERO-GAS
• SPANGAS-1 (span gas for range 1)
• SPANGAS-2 (span gas for range 2)
• SPANGAS-3 (span gas for range 3)
• SPANGAS-4 (span gas for range 4)
Conditions for the valve assignment:
• • Once a valve has been assigned to be a sample gas valve for any AM it must not
be used for zero or span gases !
• • The zero valve of an AM can not be a span valve of the same AM.
• • All gas types have to be assigned to a system-valve.
• • TFID has internal valves to be assigned separately as system valves!
