4.9Output Hold

4.9.1Output hold, is a function which freezes all output signals at the last value to prevent the occurrence of wild distortions during programming and maintenance.

4.9.2When the Operation Menu is entered by pressing CALL, the alarm relays and the analog outputs are automatically placed on hold and remain on hold until the instrument returns to on line. The output hold will remain for a maximum of 10 minutes after the last button was pressed, if this feature has been enabled. See Section 4.8.

4.10Parameter and Operation Checking

4.10.1The instrument continuously checks all parameters in its memory, while taking D.O. readings. When it detects an invalid value, it flashes the LEDs in the operation menu to indicate the parameter is at fault. You must then access the operation menu to take corrective actions.

4.11Simulated Input for Testing

4.11.1TEST is function for test and diagnostic purposes. Values can be simulated internally and adjusted with the arrow buttons to set display reading and analog outputs to any desired value without disrupting instrument calibration.

4.12Utility Menu

4.12.1The Utility Menu is provided to enable authorized personnel to change the range and fine tune the analog . See Section 7.0.

4.13Watchdog Timer and Self Diagnostics

4.13.1The DOCN600 continuously monitors the condition of all key components of the measuring system to ensure that the measurements are reliable. Invalid entries and memory loss are indicated on the panel. See Section 8.0.

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.
