    2000 ppm users need not perform this adjustment. The CD-1300-ST series ships from the factory set for an analog output range of 0 to 2000 ppm. This range can be changed to any sub-range between 0 and 5000 ppm by changing two parameters: The low output threshold is the concentration at which the analog output will begin to rise.
