... Reading 0 independently of the measured sample.
Broken cable.
Replace the cell.
... Unstable reading.
... Impossible calibration.
Dirty measuring electrodes or air bubbles on their sur-
face.
Clean or shake slightly the cell.
... The obtained readings differ a lot from the real values.
Verify that the conductivity is covered by the measuring
interval of the cell.
Re-calibrate using standards in good conditions.
.... slow cell response
Regenerate the cell.
