Upper display shows the present measured value, while lower display shows the 0. 0%Sat. Dip the DO electrode into 0%Sat solution. Wait for the upper display value to stabilise. Meter blinks the cal values for few seconds and prompts for the 100%Sat calibration. Upper display shows the present %Sat value and lower display shows the pressure compensated 100%Sat value. Remove the probe from the zero solution and wash it well in clean water. Remove excess water from the probe using a soft towel. After the upper display reading stabilised, press enter to confirm the reading. [. . . ] The presence of dissolved salt lowers the sample's ability to dissolve oxygen. Therefore a sample with a high level of dissolved salt will contain less oxygen than a sample with less or no salt at the same temperature and pressure. Fortunately, the relationship between dissolved salt or salinity and dissolved oxygen is well defined. The CyberScan DO 1500 uses this fact to provide accurate dissolved oxygen measurements in samples whose salinity range from 0 to 45 ppt. 43 Instruction Manual CyberScan DO 1500 9.
