We have a DT-470 temperature sensor in the cryostat of the project I'm currently working on. The problem is that our software is displaying the wrong readout. I'm trying to figure out how to display the correct value in Kelvin.

I've got the following to work with:

The software has the ability to apply a polynomial to a raw value (i.e. a value that's read out from the electronics), as well as apply a user-configurable function to a value. That is usually used for convenience like electronics giving us a negative value, when we'd rather receive a positive value.

In this case, the polynomial is applied to correct the value for the way our electronics influence the raw value. Then, the user-configurable function is applied, which in this case is the polynomial that follows from the data sheet.

So the steps are:
