    Generally speaking, the greater the crest factor, the greater the energy contained in high frequency harmonics. All Multimeters have errors that are crest factor dependent. Crest factor errors of SDM3055 are listed in the AC Characteristics section of chapter 6. (The crest factor errors do not apply for input signals below 100Hz.)
