Abstract
A method for the operational test measurement of a lambda probe, particularly for the purpose of calibrating and/or determining the status of the lambda probe, wherein pure air is circulated around a probe head of the lambda probe is disclosed. The method has the following steps:, —insertion of the lambda probe into a flow receptacle which is separate from an engine construction, in such a manner that an air stream (L) can be circulated around the probe head; generation of an air stream (L) in the flow receptacle; evaluation of probe measurement signals (S), wherein a calibration value is obtained and/or a heating current of the lambda probe is evaluated. A device for carrying out the method, as well as a system, is also disclosed herein.
