9.1.1.2 Full-Temperature Range Error Calculations

To calculate total error across any specific temperature range, use Equation 27 and Equation 28 for RSS maximum total errors, similar to the example for room temperatures. Conditions from the example in Room-Temperature Error Calculations are replaced with the respective equations and error components for a  –40°C to 85°C temperature range below in Table 9-2.
