An intelligent electronic device with multiple functionalities that may include multiple secure accesses includes a sensor coupled with a processor. The sensor may sense electrical parameters in an electrical circuit and generate signals indicative of the electrical parameters for the processor. The processor may be configured to concurrently operate multiple intelligent electronic device functionalities. The intelligent electronic device functionalities may each include one or more functions. The functions within one of the intelligent electronic device functionalities may be mutually exclusive. Secure access to one or more of the intelligent electronic device functionalities may be enabled by entry of a user identification.

Multi-function intelligent electronic device with secure access

A revenue meter includes electronics for measuring the delivery of electrical energy from an energy supplier to a consumer through an electric circuit. A meter cover encloses the revenue meter. A keypad is located on the meter cover, and connects to the revenue meter to access the revenue meter without requiring removal of the meter cover.

A cover for use on an electric meter is disclosed which includes an optical port which aids in transmission of optical signals from an optical transmitter, such as a light emitting diode, to an optical receiver, such as a photodiode or similar. The optical port further includes lenses located in the optical transmission path to focus the optical signal, either convergently or divergently, proximate to the optical receiver thereby improving signal reception.
