RATIO FORMULA
RT = R25 x (9.0014 x 10-1 + 3.87235 x 10-3 (°C)-1 x T + 4.86825 x 10-6 (°C)-2 x T2 + 1.37559 x 10-9 (°C)-3 x T3)
T(°C) = 28.54 x (RT/R25)3 - 158.5 x (RT/R25)2 + 474.8 x (RT/R25) - 319.85)
Ratio Tolerance Examples:
At 40 °C, ratio = 1.063 ± 0.5 % (0.005)
so, ratio = 1.058 to 1.068
At 125 °C, ratio = 1.460 ± 3 % (0.044)
so, ratio = 1.416 to 1.504
