RMS LINEARITY OVER TEMPERATURE AND RMS ERROR OVER FREQUENCY

RMS linearity obtained with a sinusoidal current and voltage with variable amplitudes from 100% of full scale down to 0.01% of full scale using

a frequency of 50 Hz. Total rms error over frequency obtained with a sinusoidal current amplitude of 10% of full scale and voltage amplitude of

50% of full scale. Fundamental rms error over frequency obtained with a sinusoidal current amplitude of 10% of full scale, a voltage amplitude

of 50% of full scale, and a fifth harmonic with a constant amplitude of 40% of fundamental, unless otherwise noted.
