1. A method for calibrating a characteristic sensor comprising:

  • receiving a plurality of data values from the characteristic sensor;

    obtaining a calibration reference value from another characteristic measuring device for the characteristic sensor;

    comparing a parameter relating to at least one of the plurality of data values to a threshold value;

    temporally correlating the calibration reference value with one of the plurality of data values using a first time delay if the parameter does not exceed the threshold value or with another one of the plurality of data values using a second time delay if the parameter is equal to or exceeds the threshold value;

    calculating a calibration factor based on the calibration reference value and the data value temporally correlated with the calibration reference value; and

    interpreting the plurality of data values using the calculated calibration factor.
