conductance probe is immersed in the solution at least 1cm and make sure the temperature probe is also
immersed at least 1cm below the solution
. Slightly rotate or move the unit up and down to ensure there
are no air bubbles on the probe.
3.
When the AD value in the software interface is stable, enter the value of the selected standard buffer in
the “Calibration” box and click the probe calibration.
4.
After the calibration is complete, rinse the sensor and calibration container with water and allow to dry.
You can also directly enter the value in the “Correction Parameters” box and click “factor” and
“deviation” to calibrate the factor and deviation value.
6.1.6 DO Dissolved Oxygen Calibration
From the Calibration menu, select the Dissolved Oxygen option to enter the Dissolved Oxygen
Calibration procedure as shown below, and then ready to begin calibration.
The dissolved oxygen sensor is calibrated at the factory and can be air calibration if it needs to be
calibrated.
Specific calibration steps:
1.
Remove the dissolved oxygen sensor, clean the sensor with a clean rag (soft texture and smooth
surface), then blot the moisture on the sensor to ensure the sensor is dry.
2.
After the current state data of the instrument is stabilized (or about 10 minutes later), start calibration
