6.2.1 Temperature calibration
The new product of temperature sensor has been calibrated, and the default of the temperature source is Pt
1000.It is not necessary to calibrate again.
6.2.2 pH calibration
Get into the pH calibration interface, and the pH standard solution value (acidity) can be manually input
at the acid point, such as 4.01. Choose the key of “OK”, and press the key of “Enter”. And then, the pH
standard solution value (neutral) can be input at the neutral point, such as 6.86. Choose the key of “OK”,
and press the key of “Enter”.
6.2.3 Conductivity calibration
Get into the interface of conductivity calibration, and manually input the concentration value of
conductivity standard solution at the site of “calibration”. And then, choose the key of “OK”, and press
the key of “Enter”. At the same time, the unit of TDS and salinity (ppt) can be switched in this interface.
If it is switched into the unit of TDS, the “real time” will display the value of TDS.
