Setting the salinity coefficient
Salt dissolved in water will influences oxygen content of water. If your sample belong to high concentration liquids, please make sure that you have selected
an applicable salinity coefficient before measurement. For the low concentration liquids, please use the default coefficient 0.0 ppt.
1. Press and hold the key for 3 seconds to enter the setup menu and the or key until the meter shows SAL/P-03.
2. Press the Enter key, the meter shows the default salinity coefficient (0.0 g/L).
3. Press the or key to set the salinity of sample, press the Enter key to confirm. Setting is completed.
DO Calibration in % Saturation Mode
The Bante821 dissolved oxygen 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-saturated water. If the 2 points calibration is selected, the zero oxygen solution needs to be used.
Single point calibration - 100% saturation
1.1 Ensure that the meter shows measurement unit “%”and you have selected 1 point calibration in the setup menu. Press the Cal key, the meter shows
100.0%/CAL 1.
1.2 Hold the dissolved oxygen probe in the air at 100% relative humidity or place the probe into the air-saturated water for 15 minutes. Press the Enter
key, the meter begins the calibration, the Calibration icon continuously flashing.
1.3 Wait for the reading to stabilize, the meter automatically shows END. Calibration is completed.
