ENERGY LINEARITY REPEATABILITY

Total energies obtained from a sinusoidal voltage with an amplitude of 50% of full scale and a frequency of 50 Hz, a sinusoidal current

with variable amplitudes from 100% of full scale down to 0.01% of full scale, a frequency of 50 Hz, and the integrator off. Fundamental

energies obtained with a fundamental voltage component, with an amplitude of 50% of full scale in phase with the fifth harmonic, a

current with a 50 Hz component that has variable amplitudes from 100% of full scale down to 0.01% of full scale, and a fifth harmonic with a

constant amplitude of 40% of fundamental, and the integrator off. Measurements at 25°C repeated 30 times, unless otherwise noted.
