FREEZING ITEMS FOR DISPLAY IN ELECTRONIC WATTHOUR REGISTER An electronic register for an electric watthour metering system includes a display buffer for receiving, at substantially the same time, all data items to be displayed. The data items in the display buffer are scrolled to a display in sets appropriate for the capacity of the display. Each set is maintained on the display for as long as required for human reading. The displayed items, having been taken into the display buffer at the same instant, are consistent with each other regardless of the length of time required to complete the display sequence. |
