Thank you very much for the Excel document! It helped me a lot.
But I found an error:
Constant aa5 value -0.61893395 (H30) is wrong. It must be -0.61899395.

Hi Shane,
is there a formula could i used to compute ( a4 b4 a7 b7 c7 results of Nominal current Calibration ) I cant find any formula for this equation . i find it in may sensor calibration certificate. hope you can give me idea how can i compute.

Could you check out about the titles:
i. Above Zero Calculator 0.01 °C to 660.323 °C
ii. Below Zero Calculator -189.3442 °C to 0.01 °C
iii. K and not °K
