H.W1: An iron-constantan thermocouple, according to tables, gives an e.m.f. of 0 mV at 0 °C, 5.628 mV at 100 °C and 21.846 mV at 400°C. It is to be used to measure temperatures in the range 0 to 400°C. What will be the non-linearity error, as a percentage of the full-scale output, at 100°C if a linear relationship is assumed over the full range?
