1 NOTE: 16-bit integers have a maximum value of +32767. Certain measurement parameters (for example, mixing ratio and enthalpy) can exceed this value in x100 scaling. In such cases, the value of the parameter is cut off at +32767, and measurements above this value are not reported. Verify that the measurement ranges in your application are suitable for the 16-bit integer format with x100 scaling; whenever possible, it is recommended to use 32-bit float values.
