6.2.4 Dissolved oxygen calibration
The new product of dissolved oxygen sensor has already been calibrated. If it is necessary to be calibrated,
the way of air calibration can be adopted.
6.2.5 Depth calibration
Make sure it is clear and dry for the depth sensor before calibration. The calibration for depth sensor is
mainly the calibration for the pressure of atmosphere, so please make sure that the depth sensor is in the
air, and not immerged in any container. Click the key of “calibration of atmosphere pressure” when the
value of atmosphere pressure is stable in the calibration interface. Then, the system will automatically
save the data to complete the calibration. Because of the particularity of depth sensor, frequent calibration
is recommended to make sure the accuracy of data.
