  • Page 10: General Description

    3 General description The DIZ meter is a digital 1- or 2- tariff meter for measuring positive- and negative active energy in 2-, 3- and 4-wire networks. Tariff switching takes place via an external control input. DIZ meters are principally used for energy data registration in the industry and building installation, switching stations and the field of energy supply.
