1-Point (Span) Calibration
To calibrate the span for the Free Chlorine System:
1.
Draw a sample with a syringe from the process water in the sample chamber and check the
concentration with a lab meter. For the most accurate calibration the reading should be above 1 ppm.
2. Perform a 1-point sample calibration using the reading from the lab meter.
The complete calibrate menu for free chlorine is shown.
