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 [10] will appear.
If the pH value during the calibration process is very different from the expected one, (e.g., defective sensor, etc.),
display [10] will indicate "E2", not allowing calibration.
If the pH measure is unstable during the calibration process, code "E3" will appear in display [10]. In addition, the
pH-sensor calibration will not be allowed.
6.3. Maintenance of the pH sensor
1. Ensure that the sensor membrane remains moist all the time.
2. If the sensor in not going to be used for a long period, keep it submerged in a pH=4.0 conservation solution.
3. To clean the sensor, avoid the use of abrasive materials that can scratch the sensor surface.
4. The pH sensor is a consumable part and will need to be replaced over a period of time.
