Abstract: Continuous monitoring of an electric power system during testing of a primary electric power meter is described herein. Electric power system signals or test signals may be selectively supplied to the primary electric power meter. Electric power system signals may be supplied to a secondary meter while a test signal is applied to the primary electric power meter. The secondary meter may record and/or transmit monitoring functions and communicate the results of the monitoring functions to the primary electric power meter while the test signals are supplied to the primary electric power meter.
