Are you sure that they are actually table entry errors, or are they actually
different slopes/calibration points? It was not till after I had sent the
mail, and was closing the browser window that I realised this table has 7
different Pt100 references in it, depending on the 100 ohm temperature (0C
or 32F, it would be easy to select the F table instead of C), and the alpha
value of the resistor. I gave just the first one (00385 Alpha) and it looks
like this is probably the most common used. I had not realised that there
are different Alpha values available.

I'm sure!  I think it was in a PDF.  I don't have the time to re-search for
incorrect data to prove it to you.  If you don't believe me, that's ok!

No problem, I'm sure you probably did find an error. I'm no stranger to
making errors myself :))) I just figured that what I observed in the table
after I sent the message may have been the reason.
