The instrument simultaneously sample for three phase voltage and current. Rotary photoelectric coding switch and LCD are used for human-computer interaction. it makes the interface compact and efficient. Utilizing the function of positive and negative edge trigger of the programmable counter array unit in MPU, signal zero-cross is captured for the phase detected based on double way. The software synchronism sampling method based on real-time parameter self-optimizing minishes period truncation error, and the measurement accuracy is improved. The digitization power measure imports traditional two-unit and three-unit methods and expands application range of the instrument. The capacity is discriminated by soft ware table-look-up on the load loss. The value of a quantity is converted to the value when reference temperature (75 ℃) from test temperature.
