FUNDAMENTAL ENERGY AND RMS LINEARITY WITH FIFTH HARMONIC OVER SUPPLY AND TEMPERATURE
Figure 20 through Figure 25 were generated using the following conditions: fundamental voltage component in phase with fifth harmonic;
current with a 50 Hz component that has variable amplitudes from 100% of full scale down to 0.033% of full scale and a fifth harmonic with
a constant amplitude of 17% of full scale; power factor equal to 1 or 0 on the fundamental and fifth harmonic. Figure 20, Figure 21, Figure 23, and
Figure 24 were generated using a voltage with a 50 Hz component that has an amplitude of 50% of full scale and a fifth harmonic with an
amplitude of 5% of full scale. Figure 22 and Figure 25 were generated using a voltage with a 50 Hz component that has variable amplitudes
from 100% of full scale down to 0.033% of full scale and a fifth harmonic with an amplitude of 5% of full scale.
