Page 21: Chapter 4 Calibrate
Calibrate Zero point calibration Even in the absence of ozone, the Rosemount 499AOZ sensor generates a small signal called the zero current. Failing to correct for the zero current can introduce a bias, particularly if the ozone 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 22 Calibrate Rosemount 499AOZ Dissolved Ozone Sensor...

Page 23: Chapter 5 Maintenance
Maintenance Maintenance Periodic maintenance and cleaning are required for best performance of the sensor. Generally, the membrane and fill solution should be replaced every four to six months. Sensors installed in harsh or dirty environments require more frequent maintenance. The optimum maintenance frequency is best determined by experience. - Page 24 Place a drop of electrolyte solution on the cathode; then place the membrane assembly over the cathode. Screw the membrane retainer in place. The sensor may require several hours operating at the polarizing voltage to equilibrate after the electrolyte solution has been replenished.
