Note 
•  The oxygen sensor is not possible in combination with Magnos28 
•  The pressure sensor (standard, not for the ‘pressure sensor connected to outside by hose’ 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 cell 2 for two measuring cells in a series.
