Half-Wave Rectifier (DC and Even harmonic) Test
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.
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%.
