I suppose that is true - but surely there has to be calculations / 
adjustments made due to voltage loss etc. in the cable run between the 
sensor and the interface.

More importantly - any clue as to bringing the maximum output voltage 
(at the upper measuring temperature point) closer to the 4095mV level.

It seems pointless not to be using the "full scale" of the input board.

Cheers, 

Antony.
