At the beginning of each season, it is necessary to carry out a new calibration of the pH probe of the device. It is possible to carry out a 1-point calibration (pH7 solution) or a 2-point calibration (pH7 + pH10) which will be more precise.

• Bring calibration solutions
• Remove the module from the water.
• Go to the "Settings" tab of the application
• Click on “My analyzer” then on “Calibrate”
• Choose the type of calibration then follow the procedure step by step.
