ABSTRACT OF THE DISCLOSURE APPARATUS AND METHOD FOR COPYING DATA FROM ONE ELECTRONIC DEMAND REGISTER TO ANOTHER A non-volatile memory copy programmer provides temporary storage into which data can be read out from a non-volatile memory of an electronic demand register of an electric meter and from which the stored data can be written into a non-volatile memory in a replacement demand register. The non-volatile memory copy programmer also produces control signals for controlling reading and writing in the non-volatile memory. A power monitor circuit in the demand register enables the storage of data from a volatile memory to the non-volatile memory in the event of a loss of power and enables restoring the data from the non-volatile to the volatile memory when the power is restored. The power monitor circuit recognizes a power loss resulting from the removal of the demand register from the electric meter in the same manner as it recognizes a normal power loss so that, when the demand register is removed for service or troubleshooting, the installation-specific data and the billing data contained in the volatile memory are safely transferred to the non-volatile memory. If replacement of the demand register is required, the non-volatile memory copy programmer enables the copying of the data from the non-volatile memory in the removed demand register to a non-volatile memory in a replacement demand register.
