Refer to the toroidal conductivityProgramming flow diagram to complete this function.1.234µS/cm 25.0ºCSN Slope2.00%/ºC8.5.8Ref TempThe display screen for manually Entering the Reference temperature isshown. The default value is displayed in bold type. Refer to the toroidalconductivity Programming flow diagram to complete this function.1.234µS/cm 25.0ºCSN Ref Temp(25.0ºC normal)+25.0ºC8.5.9FilterThe display screen for entering the input filter value in seconds is shown.The default value is displayed in bold type. Refer to the toroidal conductivityProgramming flow diagram to complete this function.Using the highest range (90mS to 1500mS) in very low conductivityprocesses below 100µS (conductance) might generate a high noisevalue relative to the actual process value. In these cases, it is recommendedto increase the input filter setting above the default valueof 2 sec. to suppress the effect of noise.1.234µS/cm 25.0ºCSN Input filter02 sec8.5.10Custom SetupThe display screens for creating custom curves for converting conductivityto concentration is shown. Refer to the toroidal conductivityProgramming flow diagram to complete this function.1.234µS/cm 25.0ºCSN Custom CurveConfigureEnter Data PointsCalculate CurveWhen the custom curve data entry is complete, press ENTER. The displaywill confirm the determination of a custom curve fit to the entereddata by displaying this screen:1.234µS/cm 25.0ºCSN Calculate CurveCustom curvefit completed.In Process Calrecommended.If the custom curve fit is not completed or is unsuccessful, the display willread as follows and the screen will return to the beginning custom curvescreen.1.234µS/cm 25.0ºCSN Calculate CurveFailure56 Programming Measurements
