< Problem with the sample >
The response is slow
Cause Solution
The conductivity electrode is dirty. Clean the conductivity cell.
The conductivity electrode is broken. Replace the conductivity cell.
There are air bubbles between the
conductivity electrode sleeve and
metal rings.
Shake the conductivity electrode to remove
the air bubbles.
Cause Solution
There is a motor or other device causing
electrical interference.
Measure at a place where no influence from
induction is given. Ground all AC-powered
equipment.
The conductivity electrode is not
connected correctly.
Connect the conductivity electrode properly.
Cause Solution
Some effects of the sample. Response time may slow down, depending on
the properties of the sample solution.
Cause Solution
The conductivity electrode is dirty. Clean the conductivity cell.
The conductivity electrode is broken. Replace the conductivity cell.
