Problem 3 (30 pts.) A J-type thermocouple is calibrated against an RTD standard within 20.02°C between 0º and 200°C. The emf is measured with a potentiometer having 0.005 mV resolution and an uncertainty of 0.045 mV over its operating range. The reference junction temperature is provided by an ice bath. The calibration procedure yields the following equation: T(°C) = 0.11 + 19.16V - 0.06V2, where the units of voltage V is mV. This second order curve fit has an error...

Problem 3 (25 pts.) A J-type thermocouple is calibrated against an RTD standard to within £0.02°C between 0° and 200°C. The emf is measured with an A/D converter having a resolution of 0.075 mV. The reference junction temperature is provided by an ice bath. The calibration procedure yields the following linear equation: T(°C) = 0.11 + 19.2V ,where the units of voltage Vis mV. This first order curve fit has an error of 0.5°C. Part a) 15 pts....
