The invention relates to an electric meter (1) for measuring the electricity consumption of a load (RLOAD), in particular during a charging process of an electric car. The electric meter (1) according to the invention contains a current output (5, 6), in particular with two current connections (5, 6), for connecting a connecting cable (7) leading to a transfer point (9, 10), in particular in a plug (8) of the connecting cable (7), whereby the load (RLOAD) is supplied with an electric current (ILOAD) via the connecting cable (7) at the transfer point (9, 10). Furthermore, the electric meter (1) according to the invention contains a measuring circuit (11, 12) for measuring at least one electrical consumption variable of the current (ILOAD) flowing via the current output (5, 6) to the load (RLOAD). The invention provides that the electric meter (1) can optionally be operated in one of several operating modes, whereby the operating modes differ in the consideration of line losses in the connecting cable (7). Furthermore, the invention comprises an associated operating method.
