Note
The zero filter (activated carbon filter) should be placed close to the sensor. It takes a time to be a
reduced residual chlorine concentration at the sensor if the pipe between the zero filter and the
sensor is long. The calibration error (E-13) might occur if the sample water stays long time in the
sensor. Refer to “ Calibration ” (page 53).
