1)
Counter counts high, when the Lambda probe does not supply a signal (e.g. probe cold). The value can rise to 127, when e.g. the probe heating or the probe wiring is defective. Check in "Read measured value block" function!
2)
The specifications are valid for an altitude up to max. 300 m above sea level.
3)
Before initiating the basic setting the value must be 4...10 (corresponds to 85...105 °C).
