Slow response or instability

. Check that the cell is not dirty, that there are no traces of oil or air 

bubbles inside it. If you work with a black Platinum cell, new platinum-coating of the electrode 
could be necessary. 

Cell constant value not accepted

. Check that the standard solutions are in good condition, that the 

probe's constant cell value coincides with that selected in the instrument and that the solution tem-
perature is within the range 15…35°C.
