calibscale_available sysfs attributes represents the range of
acceptable values.

+Description:
+               Hardware applied calibration offset (assumed to fix production
+               inaccuracies). Values represent a real physical offset expressed
+               in SI units (m/s^2 for accelerometer and rad/s for gyroscope).
