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.
