Error messages and trouble shooting

Troubleshooting

his section describes causes and actions to take for problems that customers frequently ask.

The indicated value fluctuates

< Problem with the electrode >

< Problem with the instrument >

< Problem with the sample >

The response is slow

Cause

How to solve problem

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

How to solve problem

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

How to solve problem

Some effects of the sample.

Response time may slow down, depending on
the properties of the sample solution.
