    Derek,

    The notation "m%FSR" just means "milli-percent FSR". For example, if you were to read 5m%FSR that translates to 0.005%FSR.

    The calibration registers compensate for gain and offset based on the codes entered into the gain and offset calibration registers. The device does not perform any self-calibration, so if all that is done is clicking on the Calibration Enable toggle, nothing will happen automatically. The user must enter calibration values into the gain and offset fields of the GUI.
