crest factor from 1.0 to 2.0 additional error + 3.0 %
crest factor from 2.0 to 2.5 additional error + 5.0 %
crest factor from 2.5 to 3.0 additional error + 7.0 %
Maximum crest factor of the measuring signal:
crest faktor 3.0 @ 3000 digits
crest faktor 2.0 @ 4500 digits
crest faktor 1.5 @ 6000 digits
