Operation – Dissolved Oxygen Measurement Mode
Operation in the Dissolved Oxygen measurement mode comprises an Operating Page and a Calibration Page. The Operating
Page is a general use page in which parameters are viewed only and cannot be altered. To alter or program a parameter, refer
to the programming pages in Section 7. The Calibration Page allows a calibration to be carried out. A 5-digit calibration code is
used to prevent unauthorized access to the sensor calibration page. The value is preset at 00000 to allow access during
commissioning, but should be altered to a unique value, known only to authorized operators, in the Set Up Outputs page – see
Section 7.4
