(57) In order to obtain a simple circuit design for a high-precision measuring device (1a, 1b) current and voltage signals (I and U) of a consumer (2) are fed to a multiplexer (3) and multiplied with each other after digitization. To compensate external phase angle errors, various waiting cycles (ti, tu) are produced between the current value and t he voltage value (I and U) in the digital signal. The invention provides a measuring device (la, 1b) and a process therefor. The invention i s preferably to be used in electricity meters.
