7.1.6 One-point calibration sequence
The one-point calibration of the OPTOD sensor is performed by positioning the pre-cleaned sensor in the
air above the water surface to create steam-saturated air conditions (100% oxygen saturation).

7.1.7 Two-point calibration
A sodium sulfite solution (concentration < 2 % by weight) is used as the zero point calibration
solution for the two-point calibration sequence. The general condition of the sensor must be
checked before starting the sequence.
