7-2. Precautions when Preparing a Calibration Curve
* Prepare the calibration curve with the same sensor as when measuring
the sample. If the sensor is different, accurate measurements cannot
be made.
* Prepare the calibration curve in the same environment as when
measuring the sample. Errors will become particularly large if the
temperature changes.
* In cases where the temperature at the time of measurement differs with
the seasons or other factors, prepare and enter multiple calibrations
curves for each temperature.
