The sensor incorporates a passive 4-20 mA two-wire interface, i.e. the power supply is provided externally e.g. via the controller. ® • Safety requirements are automatically met if the sensor is connected to a ProMinent control- ® ler (e.g. DULCOMETER D1C).

• Same sample water and sensor temperatures (wait approx. 15 min.). Zero Point Calibration If a ProMinent controller is being used to operate the sensor there is no need for zero point calibration. Zero point calibration should be carried out, however, if operating the sensor in the lower measurement range, or if using the 0.5 ppm variant.
