Refilling Electrolyte Solution for DO Probe
1. Take out the DO probe from the packaging. Unscrew the membrane cap from the probe.
2. Fill the membrane cap halfway with electrolyte solution.
3. Screw the membrane cap onto the probe, excess electrolyte will drain out.
4. Be sure the cathode of probe makes contact with membrane cap, the electrolyte solution in membrane cap should be without an air bubble.
Connecting the DO Probe
1. Place the DO probe into left or right sides of the electrode arm.
2. Insert the 6-pin connector into corresponding connector socket, ensure that the connector is fully seated. After connection is completed, DO NOT
pull on the sensor cord. Always make sure that the connector is clean and dry.

3. Press or key to set the barometric pressure value, press ENTER key to confirm. The meter goes to calibration point selection mode, the
display shows 1 point calibration.
4. Press or key to select the number of calibration points, press ENTER key to confirm. The display shows concentration unit “mg/L”.
5. Press or key to select the measurement units, press ENTER key to confirm. The meter shows “HOLD/NO” indicating that the auto-hold
function is disabled.
If the auto-hold function is enabled, the meter will automatically sense a stable endpoint reading and freeze it. If you disable this function, the meter
allows you to freeze the reading by pressing the HOLD key.
6. Press or key to enable or disable the auto-hold function, press ENTER key to confirm. The meter shows “OFF/NO” indicating that the auto-off
function is disabled.
When the auto-off function is enabled, if you do not press any keys within 3 hours, the meter will automatically turn off.

DO Calibration in % Saturation Mode
Bante810 benchtop dissolved oxygen meter can be calibrated quickly in air. In the percentage saturation mode, the meter is able to perform either 1 or 2
points calibration. For single point calibration, we recommend that you perform 100% saturation calibration in the air. For the 2 points calibration, you need
to use zero oxygen solution.
100% SATURATION CALIBRATION:
1.1 Make sure that you have selected 1 point calibration in the setup menu.
1.2 After the DO probe connected with the meter, turn the meter on 10 to 15 minutes to polarize the sensor.
1.3 Press CAL key, the meter shows “CAL1/100%”.
1.4 Hold the DO probe in the air or place the sensor into air-saturated water for 3 to 5 minutes. Press ENTER key to confirm. Wait for the measured
value to stabilize, the display shows “END”. Single point calibration is completed.
2 POINTS CALIBRATION:
2.1 Make sure that you have selected 2 points calibration in the setup menu.
2.2 Repeat steps 1.2 to 1.4 above. When the first calibration point is done, the display shows “CAL2/0%”. The meter prompts you to continue with
second point calibration.
2.3 Submerse probe in the zero oxygen solution, stir the sensor gently.
2.4 Press ENTER key to confirm. Wait for the reading to stabilize (this can often take more than 10 minutes), the display shows “END”. The meter
returns to measurement mode. Calibration is completed.
Performing a percentage saturation calibration will simultaneously calibrate the corresponding mg/L ( or ppm ) concentration value. Therefore,
additional mg/L calibration isn’t required in most circumstances.

Temperature Calibration
During the measurement, if the temperature reading displayed differs from that of an accurate thermometer, you need to calibrate the meter.
1. Press oC key to enter the temperature calibration mode, the meter shows current temperature reading.
2. Press or key to set temperature value.
3. Press ENTER key to confirm. Calibration is completed.
Measurement
Bante810 benchtop dissolved oxygen meter is suitable for measuring the water, wastewater, brine and other liquids. If you use meter to measure seawater
or other water containing large amounts of salt, please set the salinity coefficient before use.
Some gas and steam such as chloride, sulfur dioxide, sulfureted hydrogen, ammonium, carbon dioxide and iodin can permeate the membrane via diffusion. So
their existence will influence the measurement of dissolved oxygen.
If the sample contains solvent, grease, sulfide and alga, the membrane will be blocked, damaged or eroded.
1. Press MEAS key to turn on the meter, wait for 15 minutes to polarize the probe.
2. If necessary, to set the barometric pressure and salinity coefficient in the setup menu (Refer to “SETUP MENU” section).
3. Submerse probe in the sample solution, make sure the temperature sensor on the probe is fully immersed.
4. Stir the probe gently, wait for the reading to stabilize, record the measured value on the display.
Hold Function
Bante810 benchtop dissolved oxygen meter contains two data hold modes. When the Auto-Hold function is enabled, the meter will automatically sense a
stable endpoint reading and freeze it, “HOLD” indicator appears on the display. If the Auto-Hold function is disabled, press key, the meter will immediately
freeze currently displayed value. Press the key again to release the measured reading, you can continue to take measurement.

DO Probe Care and Maintenance
●Please always keep probe’s membrane moist.
●If you do not use the dissolved oxygen probe for long periods, please screw off membrane cap and rinse the probe's cathode, anode and the
membrane with deionized water, then soak up residual water on them with filter paper, and install the probe.
Troubleshooting
