PURPOSE: An electronic power meter system is provided which does not use a meter chip and selects desired specification of a voltage sensor and a current sensor. CONSTITUTION: The electronic power meter system comprises a micom(50), a voltage sensor(51), a current sensor(52), a LCD display unit(55), a communication selection port(60), a switching unit(57) and a power supply(70). The current sensor and the switching unit are connected between the power supply and a load(74). The voltage sensor is connected between the power supply and the micom. The communication selection port and an EEPROM(53) and the LCD display unit and the current sensor and the switching unit are connected to the micom. A real time clock(54) is connected to the EEPROM where a battery(72) is connected. An optical communication port(56) is connected between the micom and the communication selection port.
