Creating Calibration Polynomial

Many measurement instruments do not have a linear measurement scale, and require a more complex equation to properly scale them to engineering units in a dataTaker data logger. However, you can use Microsoft Excel to create the correct polynomial equation using the calibration sheet included with these devices. All that’s required is Microsoft Excel (or Openoffice.org Calc), and the calibration sheet for the measurement device, which in this case will be for a thermistor.
