半波整流（直流電源和偶次諧波）試用
Half-Wave Rectifier (DC and Even harmonic) Test
為保護勘界的正確性，勻衡電位差匹配應即為被試表的電位差匹配，做好是與被試表同尺寸的儀容儀表。
In order to ensure the accuracy of measurement, the balanced impedance should be equal to the impedance of DUT. The same type of instrument as DUT is strongly recommended.
半波電流量中有效直流變壓器，基波和偶次諧波，戰勝困難好處1級表的測量誤差應較小于3%，2級表的測量誤差應較小于6%。
Half-Wave current contains Direct DC component, Fundamental harmonic and Even harmonic, the error of the Class 1 meter should be less than 3% and the error of Class 2 meter should be less than 6%.
