ME365 PRELAB 5A FALL 2011 1) After reading lab 5, answer the following questions: a. List five performance characteristics a static calibration should provide. b. Why is the Wheatstone Bridge necessary when using the RTD? c. What should I do if the output voltage is –25 mV when the RTD is placed in the ice bath, knowing that the ADC range is 20mV? d. Why is it necessary to record temperature data when both heating and cooling the liquid?

Fill in the following table Table 3: Static Performance Characteristics Parameter Formula Value adjusted b). where does the maximum nonlinearity and maximum hysteresis occur? What are the values of the maximum nonlinearity and maximum hysteresis? (Note: it is recommended you create a code to perform these calculations as you will need it again in Lab 5a)...
