Selection of Measurement Gas
Combustion gases contain moisture created by burning hydrogen in the fuel. If this
moisture is removed, the oxygen concentration might be higher than before. You can
select whether the oxygen concentration in a wet gas is to be measured directly, or
compensated for its dry-gas value before use. Use the parameter code F02 to set the
measurement gas. For details on the parameter code, see Table 10.6, later in this manual.
