Abstract

Method for the calibration of a gas burner regulating system using a sensor (28) which is associated with the exhaust gas (29) discharged from the gas burner (10) and measures the concentration of at least one combustible or oxidizable constituent in the exhaust gas, wherein for calibration, starting from a relatively lean gas-combustion-air mixture (12) which is fed to the gas burner (10) for combustion, the gas-combustion-air mixture (12) may be enriched, specifically until the measurement signal which is provided by the sensor (28) first increases and then reduces to approximately zero, wherein the gas-combustion-air mixture (12), in which the measurement signal which is provided by the sensor (28) amounts to approximately zero, is defined as a gas-combustion-air mixture (12) with a stoichiometric combustion air ratio of λ=1, and wherein starting from this gas-combustion-air mixture (12) the gas-combustion-air mixture may be enleaned to a desired combustion air ratio of λ>1.
