ABSTRACT:
An arrangement such as a consumption meter has an external power supply. The is provided with an electronic display and/or a communication interface for reading and/or writing a content of a memory. When the external supply voltage is absent at least the electronic display and/or the communication interface as well as an electronic write/read device of the memory are supplied with energy from the exterior by a contact-less power supply, for example by means of a solar cell. Thus the content of the memory can be read and/or parametrised without the presence of a mains voltage, without a battery, without troublesome connections for an external voltage source and for example in the case of electricity meters without destroying security seals.
