Remove the plastic cover from the right side of the electrode arm. · Switch the meter on or off · Lock or unlock the measurement · Exit the calibration, settings and return to the measurement mode Toggle between the % saturation and mg/L (ppm) mode · Start calibration · Press and hold the key to enter the setup menu 2. Use the screwdriver to tighten the screw moderately. Set the temperature Increase value or scroll up through a list of options Decrease value or scroll down through a list of options 3. Insert the plastic cover to previous position. Confirm the calibration or displayed option Installing the Electrode Holder Take out the electrode arm from the accessory box. The base plate of electrode arm has a circular hole, the electrode arm has a connecting rod. Insert the connecting rod into the circular hole and swivel the electrode arm 90 degrees. The electrode holder is now ready to swing into desired position. Prior to Use Filling the Electrolyte Solution 1.1 Take out the dissolved oxygen electrode from the packaging. Unscrew the membrane cap from the bottom of the electrode, rinse the inside and outside with distilled water and blot dry. 1.2 Fill the membrane cap halfway with electrolyte solution. 1.3 Screw membrane cap back onto the electrode. Some electrolyte solution will overflow during this process. 1.4 Check the electrode, ensure that no air bubbles are trapped in the electrolyte solution and membrane is not creased or damaged. Remove air bubbles Adjusting the Electrode Arm After installation, if the electrode arm automatically rises or falls, you are able to adjust the screw until arm locate at any position. Connecting the Dissolved Oxygen Electrode 2.1 Follow the steps below to place electrode into the left or right side of the electrode arm. 3 I Setup 1 2 3 2.2 Insert 6-pin connector into the connector socket labeled DO.

Meter Setup The 810 meter contains an integrated setup menu for customizing the displayed option to meet measurement requirements. The following table describes the functions of each menu item. Menu Item Option and Description Salinity Coefficient Set the salinity compensation coefficient of sample. 0 to 35 g/L (default 0 g/L) Pressure Coefficient Set the barometric pressure coefficient according to the local altitude (refer to page 4). 450 to 850 mmHg (default 760 mmHg) Calibration Points Set the number of calibration points. 1 point (default) 2 points Measurement Unit Set the default measurement unit. mg/L Milligrams per liter (default) ppm Parts per million % Percentage saturation Degrees Celsius (default) Degrees Fahrenheit Auto-Hold If enabled, the meter will automatically sense and lock the measurement endpoint. Enable Disable (default) Auto-Power Off If enabled, the meter will automatically switch off if no key is pressed within 8 minutes. Enable Disable (default) Factory Reset Reset the meter to factory default settings. Note, the meter must be recalibrated. Enable Disable (default) Calibration I 4 Setting the Default Option 1. In the measurement mode, press and hold the key to enter the setup menu. 2. Press the / key to select an option, press the Enter key to confirm and switch to the next menu item. 3. Repeat the steps above until the meter returns to the measurement mode. Dissolved Oxygen Calibration The 810 meter allows 1 or 2 points dissolved oxygen calibration. If you have selected the single point calibration in the setup menu, we recommend that you perform a 100% saturation calibration in the. air-saturated water. If the 2 points calibration is selected, the zero. oxygen solution needs to be used. Note: During the calibration and measurement, the temperature sensor on electrode must be immersed in the sample solution completely, the solution should keep 0.3 m/s of minimum flow rate to avoid oxygen starvation at the membrane. Menu item Option Temperature sensor Single Point Calibration - 100% Saturation Ensure that you have selected 1 point calibration in the setup menu. 1.1 Press the Cal key, the display shows CAL1/100% To exit the setup menu without saving changes, press the Meas key. The following table describes the relationship between the altitude and barometric pressure, make sure to set a compatible parameter before the calibration and measurement. Altitude (m) kPa 0 101.3 100 100.1 200 98.8 300 97.6 400 96.4 500 95.2 600 94.0 700 92.8 800 91.7 900 90.5 1000 89.4 1100 88.3 1200 87.2 1300 86.1 1400 85.0 1500 84.0 mmHg Altitude (m) kPa 760 1600 82.9 750 1700 81.9 741 1800 80.9 732 1900 79.9 723 2000 78.9 714 2100 77.9 705 2200 76.9 696 2300 76.0 688 2400 75.0 679 2500 74.1 671 2600 73.2 662 2700 72.3 654 2800 71.4 646 2900 70.5 638 3000 69.6 630 3100 68.7 mmHg 622 614 607 599 592 584 577 570 563 556 549 542 536 529 522 515 1.2 Hold the dissolved oxygen electrode in the air at 100% relative humidity or place the electrode into the air-saturated water for about 10 minutes. Press the Enter key to begin the calibration. 1.3 When the reading has stabilized, the meter will show and return to the measurement mode. 5 I Measurement 2 Point Calibration Ensure that you have selected 2 points calibration in the setup menu. 2.1 Repeat steps 1.1 and 1.2 above. When the first calibration point. is completed, the display will show CAL2/0%, the meter prompts. you to continue with second point calibration. 2.2 Place the dissolved oxygen electrode into the zero oxygen solution. for about 10 minutes, press the Enter key to begin the calibration. Measurement The 810 meter can be used to measure the water, wastewater, brine and other liquids. If your sample is seawater or water containing large amounts of salt, make sure to set the salinity coefficient before measurement. Some gas and steam such as chloride, sulfur dioxide, sulfureted hydrogen and carbon dioxide can permeate the membrane via diffusion. Their existence will influence the measurements. If the sample contains solvent, grease, sulfide and alga, the membrane will be damaged or eroded. 1. Set the barometric pressure and salinity coefficient in the setup menu. 2. Rinse the electrode with distilled water, place the electrode into the sample solution and stir gently. When the reading has stabilized, the meter will show . Calibration is completed. · Performing a percentage saturation calibration will calibrate the corresponding mg/L or ppm concentration value simultaneously. · To exit the calibration without saving calibrated values, press the Meas key. 3. If the Auto-Hold option in the setup menu is enabled, the meter will automatically sense a stable reading and lock measurement, the icon appears on the display. Press the Meas key to resume measuring. If the option is disabled, the meter will continuously measure and update the readings. Temperature Calibration 1. Place the dissolved oxygen electrode into a solution with a known accurate temperature. 2. Press and hold the °C key to enter the temperature setting. 3. Press the / key to modify the temperature value. 4. Press the Enter key to save. 4. Wait for the measurement to stabilize and record the reading. 5. When all of the samples have been measured, rinse the electrode with distilled water. If the meter shows ---- indicating the measurement exceeds the range, remove the electrode from the sample solution immediately. Appendix I 6 Electrode Maintenance · Rinse the dissolved oxygen electrode thoroughly with distilled water after use. · Do not touch the membrane and always keep it is clean and wet. · If you do not use the electrode for long periods, screw off the membrane cap, rinse the electrode anode, cathode, membrane cap with distilled water and blot dry.
