 Description:
 		Raw (unscaled) differential voltage measurement equivalent to
 		channel Y - channel Z where these channel numbers apply to the
-		physically equivalent inputs when non differential readings are
-		separately available. In differential only parts, then all that
-		is required is a consistent labeling.  Units after application
-		of scale and offset are millivolts.
+		physically equivalent inputs when non-differential readings are

+		ABI is preferred over the non-differential one for those chips.
