14.1.7 Submenu: Operating time temperature ranges
The overview of the times indicates how long the connected sensor has been in
operation in the particular temperature range. This can be particularly useful when
operating sensors at range limits both with regard to the temperatures and the
mechanical load. These values visualize the load on the sensor and can be used to
draw long-term conclusions regarding the deterioration/aging or operating life of the
sensor.
