Abstract
A portable programmer-reader unit for programmable time registering AC electric energy meters utilizing replaceable program control data includes plural memory locations for programming, time and date synchronization, readout, and monitoring of the coded values of identical data items included in the meter program control data. A visual display provides numerical readouts of the data items including meter readings for different time categories of electric energy measurement by said meter and indication of error condtions. Manual control and a data entry inputs control meter data communication, readouts of the visual display and modification of the data items stored in the programmer-reader unit for programming the meter. Power conserving logic circuits extend field use while operating with a battery power supply.
