kIOHIDValueScaleTypeCalibratedDiscussion
The system sets calibration properties for some types of data. For example, the built-in event driver calibrates digitizer data to the logical minimum and maximum values. If no calibration properties are set, the getScaledValue method calibrates the value to the range -1 to 1.
