    Nicla Sense - BHI260 - Is calibration affected by the dynamic range?

    Hello,

    I want to know, if the calibration is affected by the settings of the dynamic range of a sensor.

    If I calibrate the Accel/Gyro/Magnetometer with the default settings/range, and after that I change the range, are the sensors still calibrated and is the accuracy still valid?

    If I set the dynamic range to the lowest value and at calibration sometimes overflows/saturation occurs, will that prevent/affect the calibration?

    What is the preferred way to calibrate the sensors with a low dynamic range (high sensitivity)?

    Are there other settings that affect calibration?

    Hi sebp,

    Typically, each application has a corresponding range. For example, the maximum motion amplitude will not exceed much, so you can choose a suitable range for the application to obtain the appropriate accuracy. For example, some applications are suitable for using 2G range, some applications have relatively large motion and can use 4G range, and so on.
    Therefore, it is not necessary to set the range arbitrarily, but to select an appropriate range for the application.
    The calibration algorithm is only calibrated according to the data after selecting the range.
