5.2.2

Serial/parallel operation

If you are using two analyzer modules in one basic device, the analyzer modules can be operated
in series or in parallel:
• Serial operation: The sample gas flows through the analyzer modules consecutively.
To do this, connect the sample gas outlet of the analyzer module filled first to the sample gas
inlet of the second analyzer module.
• Parallel operation: The sample gas flows separately through the analyzer modules.
To do this, connect each sample gas inlet individually to the sample gas in such a way that the
analyzer modules are supplied separately with sample gas.
5.2.3

Pressure operation/Suction operation

The analyzer modules can be operated in pressure operation and in suction operation:
• Pressure operation: The sample gas is fed into the analyzer module with overpressure from
the gas line or gas bottle.
• Suction operation: The sample gas is sucked out of the analyzer module by a downstream
pump.
5.2.4

Changing the operating mode

Please observe the following points when switching between the operating modes:
• Check the mounting positions of sample gas restrictors or clamping screws at the sample gas
connections. If required, change them in accordance with the selected operating mode.
For additional information, refer to the section "Structure of the gas connections (Page 34)".
• In the menu, adapt the parameter field of the gas path.
Additional information is available in the operating manuals: References (Page 135).
• If necessary, adjust the signal frequency of the module combination.
Additional information is available in the operating manuals: References (Page 135).

Note
Equipping analyzer modules with sample gas restrictors and/or clamping screws
In the delivery state, the analyzer modules are equipped as follows at the factory:
• OXYMAT 7: With a sample gas restrictor at the sample gas inlet, otherwise clamping screws
everywhere.
• ULTRAMAT 7: Does not require clamping screws/sample gas restrictors. Subsequent
upgrading or retrofitting is not possible and not required.
• CALOMAT 7: With clamping screws only.
