A method for operating a measuring device having at least one measured value sensor for recording and forwarding measured values of a primary measured variable. To ensure a particularly high reliability and measuring accuracy, the recording of the measured value and/or the forwarding of the measured value is carried out in dependence on the operating state of the measuring device, recording of the measured value and/or the forwarding of the measured value being interrupted during a disturbance. The measuring device is wherein the measured value sensor is designed in such a manner that the recording of the measured value and/or the forwarding of the measured value is carried out in dependence on the operating state of the measuring device, wherein the recording of the measured value or the forwarding of the measured value is interrupted during a disturbance.

An electrical device includes a functional unit subdivided into a secure functional block and a non-secure functional block. The functional unit has a single transmission device for transmitting information from the secure functional block into the non-secure functional block. The functional unit has a first interface device and the first interface device is arranged in the non-secure functional block. A key is stored in the secure functional block. The secure functional block is designed to assign an identifier to a meaning using the key, to form a value pair from the identifier and a value, and to transmit the value pair via the transmission device in the non-secure functional block. The non-secure functional block is designed to transmit the value pair via the first interface.
