4. Remove the sensor from the calibration solution and rinse it with tap water.
5. Shake the sensor smoothly so that any drops of water that may be adhered to the plastic body are removed and introduce it in the
calibration solution pH=4.0 (red colour). Shake smoothly for a few seconds and press "CAL" [18] key. Once the reading has
stabilised, the pH-controller will automatically leave the calibration mode and will be operative.

ERROR MESSAGES:

If the calibration process is interrupted for whatever reason, the pH-controller will automatically leave the
calibration mode if the intervention of the user is not detected in a few seconds. In this case, "E1" indication in the
display [15] will appear.
If the pH value during the calibration process is very different from the expected one, (e.g., defective sensor, etc.),
display [15] will indicate "E2", not allowing calibration.
If the pH measure is unstable during the calibration process, code "E3" will appear in display [15]. In addition, the
pH-sensor calibration will not be allowed.
6.3. Maintenance of the pH sensors
1. Ensure that the sensor membrane remains moist at all times.
2. If the sensor is not going to be used for a long period, keep it submerged in a conservation solution at pH=4.0.
3. To clean the sensor of possible dirt, avoid the use of abrasive materials that can scratch the sensor surface. Use an acid based
sensor-cleaning solution to clean the sensor.
4. The pH sensors are a consumable part and will need to be replaced over a period of time.
