MAE 334 Lab 2 2. Based on the LinEst standard error results for your static calibrations, what do you think is the accuracy you should expect for thermocouple measurements of temperature with your laboratory arrangement? Explain. 3. Table 4.4 (in the third edition) shows the t values used for finite statistics. Based on this table and the standard error for your static calibrations, what would be the expected accuracy of temperature measurements at a 90% confidence level? 4. Discuss the results of the thermocouple transient comparison for the thermocouple probe and the simple thermocouple. Why is there such a substantial difference? Further Background In Figure 12, the simplest arrangement for a thermocouple temperature measurement is shown and described. The thermocouple shown is measuring temperature T1 while connection to the voltage measurement device is at temperature T2. Figure 13 shows another common configuration for thermocouple measurements using a known constant temperature reference (usually an ice bath) to control the temperature T2. This
