Introduction DOG-1912YS Industrial Online Optical Dissolved Oxygen Analyzer is a brand-new online intelligent digital instrument independently developed and manufactured by Boqu EIT. This dissolved oxygen analyzer communicates with the sensor through communication and accurate data. Complete functions, stable performance, easy operation, low power consumption, safety and reliability are the outstanding advantages of this ODO analyzer. The dissolved oxygen analyzer works with digital and optical dissolved oxygen sensor ,which can be widely used in industrial application such as thermal power generation,...

Installation and Wiring SIZE

Power Relay Relay-C 4-20mA COM Sensor-1

Operation Interface There are 2 modules in the main panel of the dissolved oxygen measuring instrument, LED LCD display module and button module. Users can set and adjust the parameters of the instrument through the 5 buttons on the panel. Picture 1 Operation Interface Set/Exit button Select/Shift button Down button Confirm button

Measurement interface Enter the main measurement interface after the start-up animation. When the instrument is working normally, the LED display shows the following content. Picture 2 Main interface ① Measurement value ② Unit ③ Temperature ④ Real-time date ⑤ Real time ⑥ Measurement status ⑦ 4-20mA corresponding value of dissolved oxygen ⑧ Re

Setting Press “Set/Exit Button” to enter the password input interface. Enter settings: Enter the password "3700" to enter the setup menu. Picture 4 Setting Menu

3.1 Unit In this menu, users can change the measurement method % / mg/L /ppm, and at the same time can adjust the offset to make the measurement accurate. 3.2 4-20mA In this menu, users can change the corresponding value of 4-20mA and set the corresponding effective range. 3.3 ModbusRTU communication In this menu, users can change the communication address and rate.

3.4 Temperature In this menu, users can set the temperature offset and manually set the temperature. 3.5 Simulation In this menu, users can simulate the 4-20mA current output. The current output can be verified by simulating the measurement of the IO1 (measured value) and IO2 (temperature) ports. The release relay is closed. The relay is simulated and verified.

3.6 Relayl In this menu, users can switch the relay 1 function, set the parameter alarm upper limit value, alarm return difference value, and alarm delay time. 3.8 Relay3 In this menu, users can set the relay 3 function, set the cleaning time and cleaning cycle.

3.9 Storage In this menu, users can set the storage function (default on), clear storage memory and recording interval. 3.10 Date&Time In this menu, users can change date and time according to different time zone. 3.11 Language Users can choose English or Chinese according to need.

3.12 Backlight In this menu, users can change the backlight mode of the LCD screen. The backlight can be always on or delayed off (the default is delayed off), the backlight brightness can be changed (brightness level 1-5, brightness increases), and the contrast can be changed. 3.13 Factory data reset In this menu, users can restore the current output and relay to the factory parameters.

Calibration Press "ESC" to enter the password input interface. Enter calibration menu: Enter the password "3900" to enter the calibration menu. Picture 6 Calibration menu 4.1 Parameter Calibration In this menu, users can manually change the parameters of atmospheric pressure and salinity. Picture 4.1 Parameter Calibration

4.2 Saturated Calibration In this menu, users shall put the electrode into air. When the value comes stable, press ‘Enter’ buttom. Picture 4.2 Saturated Calibration 4.3 Factory data reset In this menu, users can restore the calibration parameters to the factory parameters. Picture 4.3 Factory data reset

History Data Display Press "ESC" to enter the password input interface. Enter History Data Display: Enter the password "1300" to enter the History Data Display. Press the up and down keys to switch the display. It can store up to 1000 records and overwrite automatically if reach maximum.

Waveform Display Press "ESC" to enter the password input interface. Enter Waveform Display: Enter the password "1400" to enter the Waveform Display. Press the up and down keys to switch the display. Picture 10 Waveform Display
