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.
