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 FS clamp
1st harmonic: if the value of the 1st harmonic <0.5% of the FS clamp
2nd
49th harmonic: if the value of harmonic <0.5% of the value of the fundamental or if <0.5% of the FS clamp
