Abstract
The invention relates to an electricity meter with signal channels that are passed to a digital signal processing device and each of which has a multiplexer with downstream analog/digital converter. Voltage signals of an electrical consumer can be connected to a first input of the analog/digital converter of the first signal channel, and current signals of the electrical consumer can be connected to a first input of the analog/digital converter of the second signal channel. In order to allow the meter to be used without any circuit variation both as a four-conductor meter and as a three-conductor meter, one of the voltage signals can be connected to a second input of the analog/digital converter of the first signal channel.
