ABSTRACT:
A plurality of test stations containing a zero force insertion socket are provided for accommodating an equal plurality of electric energy meters containing a microprocessor-based demand register. Switchable circuitry is provided for applying power to each socket to configure the socket for a particular model meter and register. The locking lever of the socket provides manual input for interruption of power to the socket. Detectors monitor the presence and absence of a meter in a socket. A system microprocessor provides signals for testing the register which are applied via a removable cable from a front panel connector to the connector of the register normally used to connect the register with the meter disk rotation optical detector. A special circuit is provided for automatically resetting all digital circuits upon initiating application of power to the system.
