It is the measurer that judges the traditional measurement. The efficiency is poor and it is easy togive a false judgment.WT102 can set freelyupper andlower limit for V,A,W andalarm when measured value is out of limit with high accuracy and efficiency It is specially fit for the volumetest on product line of some manufacturers.
