A method is described for reprogramming a meter, including configuring the meter to accept user code reprogramming at meter power-up and, at power-up, providing user code reprogramming to the meter control program. The meter is configured to accept user code at power-up by executing processor boot loader code providing for optional loading of user code into the processor memory upon processor boot-up. The meter user thus can change metering functions and options without disassembling the meter or removing it from service.

Methods and apparatus for programming a solid-state meter

A disk analog display for a solid state electricity meter includes a series of segments that illuminate sequentially to indicate the direction of current flowing through the meter and the rate at which energy is being consumed by the load. The sequential illumination provides notice to a technician that the meter is completing the measurement of one energy consumption unit so that the measurement by the meter of one energy consumption unit can be accurately timed. In one embodiment, there are three segments that illuminate sequentially to indicate that the meter is completing measurement of one energy consumption unit. The segments then simultaneously blank to indicate that the meter has completed the measurement of one energy consumption unit.

A communication bus containing master and slave devices includes a monitor unit for fault tolerant communications. In the event the master is unable to communicate, the monitor automatically assumes the master communication role. When more than one monitor is connected within the communications network, the monitor with the lowest communications address assumes the master communications role. The master includes software implementation that allows an operator to obtain data from any of the slave devices via the monitor.

An interface monitor is connected with a LAN that is formatted with an RS-485 protocol and which is interconnected with a plurality of electrical distribution devices. The monitor includes a socket connection for receiving an RS-232 plug from a PC and software logic for interpreting between the RS-232 and RS-485 formats. The PC is enabled for communicating with each one of the electrical distribution devices.
