Abstract
An electric energy meter has a programmable time based measuring system carried in a sealed enclosure for mounting the meter at a metering location. A radiation sensitive external data interface receives and transmits data encoded radiations through a transparent communications window of the enclosure. Pulse data is processed by the external data interface in serial data bit transmissions in and out of the measuring system for programming, readout and testing of the system.
