Information

From the temperature coefficient alpha20 at 20 degC (equals to 293.15 K) the parameter alphaRef at TRef

                        alpha20
  alphaRef = -------------------------------
              1 + alpha20 * (TRef - 293.15)

is determined; using this value, actual resistance R with respect to the actual temperature T is calculated by

   R
  ------ = 1 + alphaRef * (T - TRef)
   RRef

where RRef is the resistance at the reference temperature TRef.
