10.3 Monitoring the working life
Sensor: Edit ▶ Working life
In the dialog Edit sensor / Working life, you can define the time inter-
val after which the sensor must be replaced. If you do not wish to monitor
the working life, then you can enter only the date of manufacture for doc-
umentation purposes.
Start-up
Date on which the sensor was used for the first time.
