The error shown in the table below shows the conversion error using the voltage-temperature conversion formula, not the error of NLTP temperature measurement.
Since the calculation error is the smallest, especially between -20 and 110 ° C, the calculation error is 0, so Eq.A is recommended when measuring the temperature in the natural environment.
Assuming -20 to 50 ° C as the normal range for temperature measurement, the average temperature coefficient in that range is -0.1939 ° C / mV. If you want to perform simpler operations, please use Eq.B.
Eq.A: Temp (℃) = -0.000000001809628*(mV)^3-0.000003325395*(mV)^2-0.1814103*(mV)+205.5894
Eq.B: Temp (℃) = -0.1939*(mV)+212.81
