WARNING! AlemHealth cannot guarantee the accuracy of calibration data received from the modality. Note that AlemHealth cannot guarantee that the manual calibration which is performed by users is done accurately.
WARNING! The accuracy of the measurements is affected by the calibration status of the monitor. Monitor calibration ensures that tones that are lighter than black are displayed clearly separately from true black, and tones that are darker than white are clearly distinguished from true white. How to calibrate the monitors is described in the software installation instructions, which are provided separately in this user guide.
WARNING! Note, that measuring functions in AlemHealth is approximate.
