Note
The pressure sensor (standard, not for the ‘pressure sensor connected to outside by hose’ option), and the oxygen sensor (option)
are internally connected as follows:
• In the output of the measuring cell 1, with a measuring cell and in the case of separate gas paths.
• In the output of measuring cells 2 for two measuring cells in series.
• The second O2 sensor (option for version with separate gas paths) is connected downstream of the sample cell 2 outlet.
