| 20090132194 | Method for Function Monitoring of a Sensor - A method for monitoring sensor function comprises the following steps: repeatedly acquiring data records comprising sensor-specific calibration data; storing the acquired data records comprising sensor-specific calibration data; analyzing changes of the calibration data over time using the stored data records; and determining time or time weighted with a load factor until the next calibration is due, using at least the changes of the calibration data over time. The resulting time or the determined time weighted with a load factor can, for example, be output in suitable form directly after determination, thereby allowing for a long-term planning of calibration, and/or it can be stored as a date or a remaining time. A comparison with a time signal or a count-down of the remaining time allows at the due date to output a request, or prompt, signal, optionally with a desired lead time. | 05-21-2009 |
