Abstract
An electric utility meter composed of: a chassis assembly (2) having elements (4) for connecting the meter between a source of electrical power and a consumer of the electrical power; a signal generating unit (30) carried by the chassis assembly (2) and electrically coupled to the elements (4) for connecting for providing a signal which is a function of the energy being supplied to the consumer, the signal generating unit including a first electrical connector (34) to which the signal is supplied; a front plate member (16,20) carried by the chassis assembly (2) and bearing legible information (48) identifying the meter; circuitry (100) for deriving information relating to the rate at which energy is being supplied to the consumer; an electrical signal conductor (72) connected to the circuitry (100) and having a second electrical connector (70) coupled to the first electrical connector (34) for supplying the signal to the circuitry (100); and an electrically actuated numeric display device (81) electrically connected to the circuitry (100) for displaying the information derived by the circuitry (100), wherein the circuitry (100), the electrical signal conductor (72), and the display device (81) form a plug-in module which is removably inserted into the chassis assembly (2) behind the plate member so that the legible information is not obscured by the module, and the first and second electrical connectors (34,70) are disposed to become coupled together as a result of insertion of the module into the chassis assembly (2).
