Graph of max. error as a function of an AC primary current (45...65 Hz) : see in
appendices, page 48.
Distortion parameters
Influence of frequency on the measurement (add to the error in the field of reference) :
2% VS from 65...440 Hz
< 3 dB de 440 Hz...1.5 kHz. See graph of max error as a function of the frequency, in
appendices, page 49.
Influence of the frequency on the phase shift : see graph of phase shift as a function
of the frequency for a current of 1 A RMS for K1 probe, and 0.1 A for K2 in appendices,
page 50.
