In the lab, you have setup a thermocouple and have used a thermistor along with an ice
bath and water at various temperatures (confirmed with the thermistor) up to 100
degrees Celsius for calibration. The calibration data is shown in the table below and
the full-scale output range is 0-5 mV.
You note that there is scatter in your data; however, you must use a linear curve fit to
efficiently process the measurements during an automated temperature measurement
process.
