1 INTRODUCTION This conductivity analyzer has been designed for continuous monitoring and control of conductivity. It is available in wall-/ pipe-mount or panel-mount versions and can be used with either one or two sensors, each with a temperature input channel. When used with two sensors, readings can be compared to produce a range of extrapolated values.
2 OPERATION 2.1 Powering Up the Analyzer 2.2.1 Key Functions Caution. Ensure connections made Menu 1 correctly, especially to the earth stud – see Section 6.3. Advance to next menu 1) Ensure the input sensors are connected correctly. Menu 2 2) Switch on the power supply to the analyzer.
