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.

The paper to analyzes because experiments "factor contribution rate".to conduct the research;Discovered "the pure factor from difference square" for the negative value is the statistic stochastic value result;When the factor function is not extremely remarkable,the factor contribution rate also is a negative value;By now should merge not the remarkable factor square the random error square,recomputation ANOVA as well as factor technical progress factor.

论文对析因试验中用于分析因子作用的"因子贡献率"进行研究；发现"纯因子离差平方和"为负值其实是统计量随机取值的必然结果；尤其当因子作用极不显著时，计算的因子贡献率常常也是负值；这时应该将不显著的因子平方和并入随机误差平方和，重新进行ANOVA以及计算因子贡献率。
