ENERGY AND RMS ERROR OVER FREQUENCY WITH INTEGRATOR ON
The sinusoidal voltage has a constant amplitude of 50% of full scale, PGA_GAIN is a gain set to 4, the sinusoidal current has a constant
amplitude of 10% of full scale, and a variable frequency between 45 Hz and 65 Hz. Fundamental quantities obtained with a fundamental
voltage component in phase with a fifth harmonic, a current with a fundamental component of 10% of full scale, a fifth harmonic with an
amplitude of 40% of the fundamental, a full scale at gain of 4 = (full scale at gain of 1)/4, a high-pass corner frequency of 4.97 Hz, and TA = 25°C,
unless otherwise noted.
