Cleaning the measuring cell
Since water stain adheres to the inside of the measuring cell as time goes along, clean it
periodically.
1.
Detach the connector cable to stop cathode rotation.
2.
Close the valve to stop the sample supply.
3.
Remove the nut, and then remove the detector.
4.
Clean the measuring cell.
J
Replacement of the string wound filter (option)
When the string wound filter contamination progresses, the reading value becomes lower than
the actual value, and stable measurement cannot be performed.
Check the condition and replace it periodically.
1.
Turn OFF the power to the converter.
2.
Close the supply source valve (front of the filter) to stop the sample supply.
3.
Loosen the housing and pull it downward.
4.
Take out the filter element inside the housing and replace it with a new one.
J
Pausing the measurement
If the sample water is not flowing while the detector is powered on the cathode electrode will
be plated with silver then the succeeding measured data will be influenced. Be sure to turn off
the power when the sample is not flowing.
1.
Turn OFF the power to the converter.
2.
Close the supply source valve of the sample water.
