Temperature range from 660.323 to 961.78 need d coefficient but I didn't see it in your excel file?
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.
Thanks Elmar. Correction made.
Hello Shane! Thanks so much for taking the time to put this together. What a timesaver this turned out to be.
Hi Shane,
could you please add a comment to the R=>T conversion including cell B22. Is there any reference to this?
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.
thanks,
AlexA
Great work. ¡¡¡Congrats!!!
