Calibrating the baking sensor
A new backing sensor electronic unit (Lambda module) that has not yet been
calibrated is synchronized automatically with the baking sensor (Lambda sensor)
that is connected.
For new appliances, this is done during the final test at the factory.
If the baking sensor module is replaced as part of a repair, automatic
synchronization between the baking sensor module and the baking sensor will be
performed the first time the mains voltage is applied.
If only the baking sensor was replaced as part of a repair, manual synchronization
between the baking sensor module and the baking sensor must be performed in
the service program.
The manual calibration is started in the (
Lambda sensor calibration
) service
program.
Here the (
Ipump
) flow of the baking sensor is sensed and stored. During operation,
this initial value is compared with the current Ipump flow. The result is displayed in
% as (
Probe service
) in the (
Lambda sensor test
) service program.
Each calibration causes the previous (
Probe service
) value to be
deleted.
Recalibration of an old sensor will again produce a (
Probe service
)
value of 100 %.
Recalibration does not improve the accuracy of the measurement!
Information on the accuracy of the measurement is possible by the level of the
baking sensor current.
