Reference peak Amplitude ± 10%
(1)
(1) Normal variation of peak amplitude is ± 10% and depends on the ambient temperature. If the initial measurement was performed in one extreme temperature and
the validation measurement is performed at the other extreme, the amplitude can differ by as much as 20%.
