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.
Syntax
R = convertResistance(RRef, TRef, alpha20, T)
