NGA-2000 System Calibration

4 Functionality

4.1 Gas flow

The gas flow through the analyzers can be configured in any way:

1.only serial

2.only parallel

3.serial and parallel mixed

Calibration gas mixtures

Connections for program logic and flow configurations:

∙To each AM (channel) must be assigned a sample gas valve.

∙During a calibration of an AM the assigned sample gas valve will be closed and returns to the OPEN-state after the calibration of the AM is done.

∙The calibration gases can only flow into an AM if sample gas valve is closed.

∙With a opened sample gas valve it is expected to actually flow sample gas.

The state of assigned sample gas valve also decides about some AM specific states!
