Cap sterilizations (only sterilizable, amperometric sensors)
The sterilization counters in the sensor make a distinction between the sensor and the
membrane cap currently used. If this cap is replaced, only the (cap) counter is reset.

Limits operating hours
The total operating time of the sensor and its use under extreme conditions is monitored. If the
operating time exceeds the defined threshold values, the device issues a corresponding
diagnostics message.
Each sensor has a limited life expectancy which heavily depends on the operating
conditions. If you specify warning limits for operating times under extreme conditions, you
can guarantee the operation of your measuring point without any downtime by
performing maintenance tasks in time.
