ABSTRACT:
A device for energizing the electronic digital display found on current kilowatt hour meters in order to read the digital display of meters that have been removed from their site location that is simple to operate. The device would allow service personnel even those inexperienced with kilowatt hour meters to read the meter even if they are located in remote areas. In particular, the structure of the device will enable service personnel or the local utility office to read the meter without having to locate an energized meter socket with the correct terminal arrangement and correct voltage, or to taking the meter to an off-site meter test shop. The device generally incorporates a 13 terminal kilowatt hour meter socket and a six terminal kilowatt hour meter socket which are connected to a 120 volt power source through a step-up transformer.
