Page 4: General Information
The “smart” Oxygen sensor stores calibration and history data within the sensor. This allows you a “plug and play” system without re-calibration. In this manual, you will find all of the information you will need to commission the Dissolved Oxygen sensor. Technical specifi- cations, detection limits and dimensions can be found in chapter 7. -
Page 5: Health And Safety Information
Devices that radiate strong electromagnetic waves can influence the measurement data or result in a malfunction of the sen- sor. Avoid using the following devices in the same room as the TriOS sensor: mobile phones, cordless phones, transmitters/ receivers and other electrical devices that produce electromagnetic waves. -
Page 6: Warnings
Make sure that the cord is not placed near hot surfaces. • If the sensor cord is damaged, it must be replaced with an original part by the customer service of TriOS Mess- und Datentechnik GmbH or by an authorized TriOS workshop. -
Page 7: Disposal Information
• Drinking water monitoring The use of other media can damage the sensor. For the use of the Dissolved Oxygen sensor in media other than those specified this manual, please contact the customer service of TriOS Mess- und Datentechnik GmbH (support@trios.de). -

Page 14: Calibration
The sensor must be kept dry during the calibration process. Drops of water adhering to the sensor mem- brane could distort the measurement. By positioning the sensor in air-saturated water (air is directed through water until the water is saturated with it). The air pressure and temperature must remain constant during the calibration.

Page 15: One-Point Calibration
The default value of the atmosphere used for the compensation is 1013 hPa. 5.3.4 Salinity The value for the salinity of the measurement medium could be transmitted to the sensor by your terminal. The default value of the salinity used for the compensation is 0 g/Kg. D01-903en201912 Manual Dissolved Oxygen... -
Page 16: Malfunction And Maintenance
If the zero point is moved, a complete two-point calibration must be carried out. NOTICE Avoid touching the membrane, because it can become scratched or dirty. If this happens, the func- tionality of the device can no longer be guaranteed. D01-903en201912 Manual Dissolved Oxygen... -
