Rapidly or continuously changing inputs may cause mis-compare readings because the measured values of the three channels may different by more than 0.5 percent of full scale, which can cause a fault to be declared in error. If the input readings differ by a minimum of 0.5 percent of full scale and continue for a minimum period of 256 input samples, the probability of a fault increases.
