The harmonics will be zeroed under the following conditions

DC: if the value of DC <0.5% of the value of the fundamental or if the DC value < 0.5% of the clamp's full scale
 1st harmonic: if the value of the 1st harmonic <0.5% of the clamp's full scale
 2nd  49th harmonic: if the value of harmonic <0.5% of the value of the fundamental or if <0.5% of the FS clamp
