I guess this is reminiscent of the staging code which had magn_range and 
scale; magn_range being the nice, human-readable measurement range (such 
as +- 1.9 Gauss)

setting the expected measurement range sounds like calibration to me...

I think this is one of the biggest issues of iio: that there is no 
guideline when to use what
