10.1.1.2 Full Temperature Range Error Calculations

To calculate total error across any specific temperature range, Equation 26 and Equation 27 should be used for RSS maximum total errors, similar to the example for room temperatures. Conditions from the example in Section 10.1.1.1 have been replaced with their respective equations and error components for a
–40°C to 85°C temperature range below in Table 10-2.
