➤ When calibration is needed ?
Calibration of your ICO's probes is necessary to ensure the reliability of the measurements sent to your application. If it is not done regularly, the pH measurements and disinfection rate (ORP) will become inaccurate may drift over time which can lead to inappropriate use of products (over or under dosing) and alter your bathing experience in your pool.
The calibration of the probes is therefore essential to keep the water healthy.
If you replace a sensor with a new one, it is not necessary to calibrate it. However, you must regenerate your new probe with KCl liquid then reset the sensor in the application when it is installed. This procedure must be carried out as soon as your new sensor is installed, and before the next calibration. It allows your ICO to take account of the factory settings. For more information, please refer to the page how to replace an ICO probe.
When you receive a new ICO, the probes are already calibrated. So you can start the season with your probes without having to calibrate them. The first calibration of your sensors should be carried out within 6 months (if you use your pool or spa all year round) OR at the start of the next season (for seasonal use).
After six months' use of your ICO (or 1 season), calibration proceeds at the following rate:
Finally, calibration should always be carried out at the beginning of the season, not before wintering.
The ICO sensor calibration kit includes :
Buy a calibration kit in the Ondilo shop.
Open the ICO application. Click on the Remote Control button.
Calibrating the pH sensor is tricky because it requires 2 measurements, with a change of solution. When you have completed the 2 steps, ICO checks the consistency of the measurements and may give you an error message if they differ. In this case, ICO will ask you to repeat all the calibration steps.
Calibration starts with the pH4 solution
Calibration takes about a minute, so make sure you keep your phone close to ICO.
Important : Nous vous recommandons de conserver la solution pH4 dans un autre récipient jusqu’à la validation de la calibration, , if you need to recalibrate.
Calibration takes about a minute, so make sure you keep your phone close to ICO.
Then click on Save
Important: We recommend that you keep the pH7 solution in another container until the calibration has been validated, in case you need to recalibrate.
In some cases, your ICO device may tell you that the calibration of your probe has not worked.
Here are the cases that may explain this message:
This ‘Calibration failed’ message appears when the difference between the two measurements is too small or too large. This means that the difference between the measurement taken in pH4 liquid and that taken in pH7 liquid is too far from the tolerated difference.
Be sure to follow the procedure described in the calibration tutorial. Careful rinsing and drying of the probes and calibration stand between each step is essential to avoid falsifying the measurements.
Before calibrating the ORP probe, rinse the probes thoroughly in clean water, then wipe them dry with a soft cloth. Do the same with the solution base
To calibrate the ORP probe :
The ORP probe calibration also takes a minute, so make sure you always keep your phone close to the ICO
Rinse the probes again and dry them, then replace the probe cover.
If, despite these recommendations, the calibration has still not worked, contact our support department.
