DO Calibration in % Saturation Mode
Bante900P portable multiparameter water quality 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 saturated anhydrous sodium sulfite solution (zero oxygen solution).
100% SATURATION CALIBRATION:
1.1 Press MODE key until the meter shows
indicator and measurement unit “%”.
1.2 Make sure that you have selected 1 point calibration in the setup menu.
1.3 Press CAL key, the meter enters calibration mode, the display shows “100%/CAL1”.
1.4 Hold the dissolved oxygen probe in the air, press ENTER key to confirm. Wait for the measured value to stabilize, the display shows “END”. Single
point calibration is completed.
