There can be several reasons of a point of 0 shift:
- The electrolyte may have been polluted by liquid entering the sensor
- Polluted junction
- Probe used in an installation with leakage currents caused by a bad earth electrode (In this case, regeneration
is pointless).
Calibration
Each sensor is characterised by its deviation and slope. These two points of measurement must be defined
using calibration solutions and sent to the connected instrument. As these characteristics tend to drift with use,
calibration must be carried out regularly. Calibration is mandatory in the following cases:
- when installing or after replacing the sensor
- After every cleaning with a cleaning solution
- After long term storage
- When the measurement results are too far from the expected results.
