What determines the maximum accuracy tolerance of the ACS750?
The maximum accuracy tolerance given for the ACS750 is based the 6-sigma limit of its accuracy distribution. Competing devices frequently specify their accuracy only over less than their full measurement range of current, at restricted temperature, and with less than full-scale current excursions to define magnetic hysteresis. The histogram below illustrates a typical distribution of ACS750 accuracy. The data is taken from a random sample of parts from 14 different manufacturing lots.
