1.8 Calibration of lambda probe
If the lambda probe over time becomes less precise, it has to be calibrated.
In normal atmospheric air the oxygen content is always app. 21 % ( O
2
). This can be
used as point of reference for the measurement of the oxygen content. The lambda
probe should be calibrated if the oxygen content in air deviates more than ± 2% from
21%. This can only be established, when the probe is exposed to
absolutely clean
atmospheric air
This is most easily done, when the boiler has been stopped for a period. There should
not be any smoke at all in the combustion room or the flue pipe, when making the test.
Close the bypass damper on top of the boiler and undo the top cleaning door to the flue
pipes, now the chimney will suck in “clean” air, passing by the probe.
