again, and avoid direct sunlight.

Click “Air calibration” in the Type B calibration

After the calibration is complete, rinse the sensor and calibration container with water and allow to dry.

Note: During the calibration process, the sensor must be protected from direct sunlight, otherwise
the performance of the dissolved oxygen sensor will be lost.

You can also directly enter the value in the “Correction Parameters” box, click “factor”, “deviation” to

calibrate the factor and deviation value, or directly input the value by clicking “salinity” and “atmospheric

pressure setting” for salinity and atmospheric pressure compensation and settings.

6.1.6.1 Salinity compensation and temperature compensation

）

Salinity compensation

The water contains a large amount of salt substances, which will have a certain influence on the dissolved

oxygen content, so that the output signal of the dissolved oxygen sensor drifts with the change of salinity.

In order to reduce this phenomenon, certain compensation measures can be taken. Correcting the output

result, to achieve a certain range, to eliminate the influence of salinity change on the output signal of the

sensor is called "salt compensation". The other conditions are the same, the greater the salinity, the lower

the dissolved oxygen.

Under normal circumstances, the sensor is calibrated under the standard 0. When the working

environment deviates, it can compensate for the effect of salinity on dissolved oxygen, ensuring

measurement accuracy, convenient use and comparison.

The probe has a salinity compensation function, and the dissolved oxygen has compensated for the

salinity in the solution in real time. If manual salinity compensation is required, the on-site salinity value

can be entered into the dialog box after salinity compensation.

）

Temperature compensation

It is necessary to take certain compensation measures to correct the output result, and to eliminate the

influence of temperature change on the output signal of the sensor within a certain range is called

“temperature compensation”. In general, the temperature of the sensor is calibrated to 25 ° C, which

compensates when the working environment deviates, which can eliminate the effect of temperature on
