A temperature sensor is being calibrated. The output is sent to the display shown. It is known that the sensor has a noise floor of \(75\mu \mathrm{~V}\). The data for two cycles of calibration is shown in the table. Using Excel a line of best fit (forced to pass through zero) has the equation: Output (mV)\(=0.4014\) input (\({}^{\circ}\mathrm{C}\)).
Determine the following characteristics of the sensor (be mindful of significant figures in reporting the values), report the errors in \(\pm \mathrm{mV},\pm{}^{\circ}\mathrm{C}\) and \(\pm \%\mathrm{FSO}\).
FSO
Sensitivity
Resolution
Zero offset error
Non-linearity error
Hysteresis error
Repeatability error

\begin{tabular}{|l|l|l|l|}
\hline Zero error & -0.17 & 0.12 & \(\pm 0.2\%\) FSO \\
