Abstract

A measurement device configured for measuring and reporting electrical measurement data is disclosed. The electrical measurement data comprising a dc voltage supplied to a processing unit and a dc current running in consequence of the supplied dc voltage. The measurement device comprises a first terminal and a second terminal, wherein the device is configured for measuring the dc voltage of the processing unit. The same terminals are also used for power supply for the measurement device. A third and a fourth terminal of the measurement device are provided, wherein the device being is for directly measuring the dc current of the processing unit using these third and fourth terminal. The measured dc voltage and dc current are wirelessly transmitted, using a transmitter, to a data processing system.
