Generally it applies that: calibrating the pO
formed after sterilisation because sterilisation can change the gra-
dient of the pO
A 1-point calibration to 100 % is generally sufficient for an exact
measurement and should be carried out again before each fermen-
tation.
The zero point (0 % calibration) should be checked at regular inter-
vals of about 6 months.
A detailed description how to calibrate the pO2 sensor can be
found in the separate touch screen software manual from the
equipment manufacturer.
