An electricity meter which, in one embodiment, includes a digital signal processor configurable for generating energy measurements for a plurality of meter form types and connections is described. In the one embodiment, the meter includes voltage and current sensor for generating signals representative of current and voltage at a load, and the digital signal processor (DSP) is coupled to the voltage and current sensors. The DSP includes a memory, and a plurality of selectable instruction sets corresponding to respective meter form types are stored in the DSP memory. The form types includes meter ANSI form 9 and meter ANSI form 16 type forms, and the instruction sets include processing steps to be executed to determine line voltages and line currents for respective meter form types. The meter also includes a microcomputer coupled to the DSP for receiving data generated by the DSP. The microcomputer is operable transmit a selection command to the DSP to control selection of one of the instruction sets stored in the DSP memory. An optical port may be electrically coupled to the microcomputer, and the microcomputer is configured to receive a control command from the optical port. The microcomputer uses the control command to generate the selection command.
