  • Page 17: Calibrate

    September 2019 Quick Start Guide Calibrate Zero point calibration Even in the absence of free chlorine, the sensor generates a small signal called the zero current. Failing to correct for the zero current can introduce a bias, particularly if the chlorine concentration is small (<0.4 ppm). Zero the sensor when it is first placed in service and every time the fill solution is changed.
  • Page 18 Refer to the manual for the transmitter you are using (Rosemount 56, 1056, 5081, or 1066). 7. After calibration, go to the Diagnostics menu and check the sensitivity. The sensitivity should be between 300 and 700 nA/ppm. For more information, refer to the transmitter manual. Emerson.com/Rosemount...

  • Page 19: Maintenance

    September 2019 Quick Start Guide Maintenance Periodic maintenance and cleaning are required for best performance of the sensor. Generally, the membrane and fill solution should be replaced every one to three months. If the sensor is being used in water having conductivity less than about 100 µS/cm, it might be necessary to replace the fill solution (but not the membrane) more often.
