Abstract: The meter includes a first processor (14) for determining electrical energy from voltage (12A, 12B, 12C) and current signals (18A, 18B, 18C) and for generating an energy signal (42, 44, 46, 48) representative of the electrical energy determination and a second processor (16) for receiving the energy signal and for generating an indication signal representative of said energy signal. An option connector (38) is connected to the first and second processors (14, 16), whereby the energy signal is provided to the option connector (38) and a communication connection (40) is provided between the option connector (38) and the second processor (16). It is also preferred to provide the option connector (38) with certain operation signals such as a power fail signal, a master reset signal, an end of demand signal, a KYZ signal, and the potential to communicate with various components of the meter, such as serial data communication, communication signals transmitted and received through an optical port and display signals. It is also preferred for the first processor (14) to include a comparator, connected to receive a precision voltage (22) and a reference voltage (28), wherein a comparator signal is generated whenever the reference voltage exceeds the precision voltage.
