5. SENSOR 5.1 Free Chlorine Sensor Use Description For new sensors, connect the sensor to power and allow to run overnight (at least 12 hours) before calibration. If the sensor will be un-powered for two hours or more, run for two hours prior to use. - Page 29 Dry stored pH sensors must be immersed in water for 12 hours prior to use. Each new sensor must be calibrated with monitor. For pH sensors, 2 or 3 points calibration is necessary. The frequency of calibration or checking the measuring sensor depends on the application conditions.
