Hello, can anybody help me understand "Λ10"?
Dirk said: "Λ10,tr is the measured Lambda Value at dry conditions with 
10 degrees middle temperature"
He then explained that "middle temperature" = "mean value". Is that the 
same as "average temperature"?

Does that mean that one side can be 2 degrees and the other side 18 degrees?

Thanks,
