NB : Accuracies given in the frequency reference range 35 to 65 Hz.
(1) Use possible from 65 Hz to 2 kHz for ratings up 400 V and from 65 Hz to 500
Hz for ratings up to 100 V, with digital accuracy: 7.5 % rdg ± 5 counts and analogue
accuracy: 7.5 %. Additional error of 1 % for a crest factor FC ≤ 3 and 3 % for FC ≤ 5.
