N O T I C E
The use of an RTC Module does not release the operator from the responsibility of maintaining
the system. No guarantees as to the functionality or operational safety of the system.
In particular, the operator must make sure that instruments connected to the RTC
open/closed-loop controller are always fully functional.
To make sure these instruments supply correct, reliable measurement values, regular
maintenance work (for example, cleaning of the sensor and laboratory comparative
measurements) is essential! (Refer to the user manual for the relevant instrument.)
N O T I C E
The combination of pre-assembled components supplied by the manufacturer does not represent
a standalone functional unit. In accordance with EU guidelines, this combination of
pre-assembled components is not supplied with a CE mark, and there is no EU declaration of
conformity for the combination.
However, the conformity of the combination of components with the guidelines can be proved
through technical measurements.
