CALIBRATION

Zero point: Even in the absence of free chlorine, the 499ACL-01 sensor generates a small signal called the zero current. Failing to correct for the zero current can introduce a bias, particularly if the chlorine concentra- tion is small (<0.4 ppm). Zero the sensor when it is first placed in service and every time the fill solution is changed. To zero the sensor, place it in a cup of deion- ized or bottled water to which a few pinches of table salt have been added to increase the conductivity. Once the sensor current has reached a stable low value, which takes at least two hours, follow the ana- lyzer prompts for zeroing the sensor. The zero current should between -10 and +10 nA. For more information refer to the analyzer manual.

Full Scale: Because stable dilute chlorine standards are not available, the sensor must be calibrated against the results of a laboratory test run on a grab sample of the process liquid. Place the sensor in the flow cell and adjust the sample flow to within the range given in the table on page 2. Also, adjust the concen- tration so that it is near the upper end of the operating range. Once readings are stable, follow the analyzer prompts to complete the calibration. Be sure taking the sample does not alter flow to the sensor and test the sample immediately after taking it. After calibration, go to the diagnostics menu and check the sensitivity. It should be between 200 and 450 nA/ppm. For more information, refer to the analyzer manual.
