MAE 334 Lab 2 Figure 1. The lab setup showing the thermocouple and thermometer in the far right cup, the orange ice bucket and the usual computer setup. Part 1 – Static Calibration 1. Obtain a supply of crushed ice and tap water including a cup of hot water. By using the tap water and adding ice to the Styrofoam cups, produce a series of five temperatures approximately equally spaced from 0 C to the temperature of the hot water, typically above 35 C. Be sure to stir the containers to ensure uniform temperatures before recording any data. There should be plenty of ice in the lowest temperature ice water and no ice in any other cup. 2. Open an Excel spreadsheet to record your static calibration dial thermometer temperatures and thermocouple data. The data can then be immediately plotted to find bad or incorrectly entered data points and analyzed using a linear regression to obtain the

Unformatted text preview: calibration slope and intercept. This calibration data must also appear in your lab notebook (calibration curves and linear regressions will be required for the lab report). 3. Place the dial thermometer and thermocouple probe in each cup of water until the thermometer reading remains constant (approximately 30 seconds). Tapping the dial thermometer gently may be helpful here. The thermocouple voltage and thermocouple temperature are to be monitored with the Virtual Bench Digital Multi-Meter (DMM). 4. The Virtual Bench DMM setup: • Place the dial thermometer on top of the aluminum ADC input box (this is to estimate the reference junction temperature which is approximately the lab air temperature) 16 Page 2 of 16...
