@SVEJK - which is correct ?

[manie]

@ SVEJK - I have downloaded this paper by Svejk a while back. Great stuff !!!

I have one question.... POSITIVE temperature calc, which one is correct......... the first one or the last one ??
Surely the calculations will give different results ??

Just to clear up in my mind thanks....

Try both routines in the simulator with a test value for the temp AD reading.

What happens ?

Well spotted Manie, there is an inconsitency in writting. While the result is the same I admit it may be confusing. Please find an updated version.

Regards,
Svejk
