S. where t = reference temperature (+0 C) and t = ambient temperature in C. Note The addition of mechanical electric contacts affects the accuracy of instruments such that % becomes.5%,.6% becomes.4% etc. (dd the 50% of accuracy; If the contact is of the magnetically assisted type, this value can t be added within the ±5% of setting point.)
