Omega CDE-45P Conductivity Sensor Part 3 –Maintenance & Troubleshooting 3.2 Troubleshooting The first step in resolving any measurement problem is to determine whether the trouble lies in the sensor or the transmitter. Since measurement problems can often be traced to surface deposits coating the electrodes, cleaning the sensor using the method outlined in Section 3.1 should always be the first step in any troubleshooting. If the sensor cannot be calibrated after cleaning, per
