Troubleshooting / Decommissioning / Repair / Disposal
If the measured value is 0.00 ppm or 4.00 mA the sensor is function-
ing correctly.
If the measured value is more than 5 mA, replace the sensor unit (see
chap. 10.2).
NOTE
• A minimal deviation (± 0.2 mA) from 4.00 mA may be due to
insufficient mixing of the solution.
• Minor and stable deviations from the zero point at 4.00 mA
can be compensated on the DULCOMETER

Decommissioning
Disconnect the sensor's electrical terminals (see chap. 7, "Installa-
tion").
Also, if temporarily decommissioning, protect the sensor membrane
