摘要： A measuring apparatus having a housing, at least one internal sensor, an electronic control unit, at least one radio module, an operating device and an information carrier. The measuring apparatus is configured to be connected to external sensors by cable and/or wirelessly, the electronic control unit is configured to convert measurement signals from internal and external sensors into digital measurement data and to provide the digital measurement data to the information carrier. The information carrier is configured to provide and display as priority, in the case of simultaneous availability of wired or wireless sensors, either the data of the wired sensors or the data of the wireless sensors. A system for performing measurement tasks and managing measurement data, and methods for starting up and/or maintaining an air conditioning system are also provided, as well as methods for starting up and/or maintaining a system.
