Experimental methodology 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....
