4.6Analog Outputs

4.6.1The analog output signals consist of a non-isolated 0-1 mA, 0-5 Vdc, and isolated 4- 20 mA signals.

4.6.2From the factory all of the analog outputs have a linear range corresponding to the full range of the instrument. The 4-20 mA output can be programmed to another linear range by entering two values:

•Output High: This is the D.O. value at which you wish to have 100% output.

•Output Low: This is the D.O. value at which you wish to have 0% output.

4.6.3When programming, you must ensure that the output range has a span of at least 10% of the full range of the instrument. For applications that require the output to decrease as the process value increases, i.e. an inverted output, the Output High value will be less than the Output Low. See Section 5.4.

4.6.4The instrument may be used to measure the temperature of the process either in Celsius or in Fahrenheit. The DOCN600 does not control temperature but the 0-5 Vdc and 0-1 mA analog outputs can be dedicated to follow the process temperature. See Sections 5.6.

4.7Operation Menu

4.7.1The operation menu allows the user to recall and to adjust the parameters, required by the analyzer functions.

4.7.2When the analyzer is powered up, the program will display D.O. readings. None of the LEDs in the operation menu will be illuminated.

4.7.3Five buttons on the panel are used to operate the menu. Use the CALL button to step through the items in the menu, one at a time. The red LEDs beside each item makes it very easy to follow the menu. The function of the RUN button is to return to the on-line D.O. display from anywhere in the menu. The analyzer has a built-in timer which, when enabled, by DIP Switch 7 Bank S1 (Section 4.8), returns the program to RUN mode if no button has been pressed for 10 minutes. This time-out has the same effect as pressing the RUN button.

DOCN600, Dissolved Oxygen System specifications

Omega Engineering has set a standard in the field of environmental testing and monitoring with its advanced Dissolved Oxygen System, the DOCN600. This sophisticated device is engineered for precision and reliability, making it a preferred choice for various applications, from wastewater treatment to aquaculture, and laboratory settings. The DOCN600's primary mission is to accurately measure dissolved oxygen levels, a critical parameter in assessing water quality and supporting aquatic life.

One of the standout features of the DOCN600 is its state-of-the-art optical dissolved oxygen sensor technology. Unlike traditional Clark-style electrochemical sensors, which can be subject to interference and require frequent calibration, the optical method uses luminescence to measure oxygen levels. This technology offers several advantages, including lower maintenance requirements, enhanced stability, and improved accuracy over a broad range of conditions.

The DOCN600 boasts a user-friendly interface, complete with a high-resolution LCD display that provides real-time data visualization. Users can access multiple display modes, allowing for quick reference of key metrics, including temperature and oxygen saturation levels. Furthermore, the system is designed with intuitive menus that facilitate easy navigation, ensuring that both seasoned professionals and beginners can operate the device with confidence.

For data management, the DOCN600 is equipped with advanced connectivity options, including USB and RS-232 ports. This allows for seamless integration with external devices and enables users to export data for further analysis. Coupled with its internal memory, which can store extensive historical data, this system empowers users to monitor trends over time, aiding in decision-making processes.

Another notable characteristic of the DOCN600 is its robust build quality, ideal for deployment in various environmental conditions. The system is engineered to be resistant to water, dust, and harsh chemicals, ensuring longevity and reliable performance even in challenging environments. Additionally, with its compact and portable design, it can be conveniently used in field applications as well as in stationary setups.

In summary, the Omega Engineering DOCN600 Dissolved Oxygen System combines cutting-edge optical technology, user-friendly features, advanced connectivity, and a durable design. It stands out as an invaluable tool for anyone needing precise and reliable dissolved oxygen measurements. Whether used in research, environmental monitoring, or industrial applications, the DOCN600 is an excellent investment for achieving accurate water quality assessments.
