Calibration 4 Introduction A number of parameters monitored by the MC10 must be periodically calibrated for optimum performance and accuracy. These are outlined below. MC10 Calibration Parameter Method of Calibration Feed Conductivity Permeate Conductivity Feed Temperature Zero Feed Temperature Span Permeate Temperature Zero Permeate Temperature Calibration with Conductivity Standard Solution Calibration with Conductivity Standard Solution Settings Index Number 23 24 Calibration to Zero Degrees C 25 Calibration to Known Temperature 26 Calibration to Zero Degrees C 27 Calibration to Known Temperature 28 Recommended Calibration Frequency One to Three Months Depending Upon Sample Condition Six Months Conductivity The conductivity inputs of the MC10 should be calibrated using a known standard solution. Value of the standard should be in the upper area of the range of the conductivity being measured by the MC10. In cases of low conductivity (< 50 uS/cm) it may be necessary to calibrate the sensor and its associated input channel in situ. This is done by following the same general procedure as outlined below for calibration to a standard solution with one exception. In situ calibration requires that the sensor be left mounted in the process line. Instead of using a standard solution, a sample from the process line is tested with a calibrated meter. This measured conductivity value of the process fluid is used in lieu of a standard solution value. The following procedure should be used for calibrating the MC10 to a solution of known conductivity. Step One – Rinse or soak the sensor in deionized water. Dry the sensor and place it in a solution of known conductivity. This may be a standard solution provided a laboratory supply company or a water sample which has been measured by a calibrated conductivity meter. Make sure that the conductivity value of the calibration solution is within the upper range of the MC10 conductivity channel. Allow the sensor to equalize to the solution temperature for a few minutes before proceeding with the next step.
Important Please note: • Temperature and conductivity are combined in one sensor. • If temperature and conductivity are both being calibrated, always calibrate the temperature first. • Be careful not to damage (avoid excessive twisting, bending, etc.) the sensor leads when removing the sensor from the pipe fitting. • Never reuse standard solutions. Always dispense the solution from its container and dispose of the solution after using it. • Use clean containers (triple rinsed with deionized water) for holding the calibration solution. Step Two – Go to the appropriate Settings data entry screen (23 or 24). Enter the value of the calibration solution via the keypad. Press ENTER. A new measured value will appear on the screen. If the value displayed on the screen does not match the value entered for the calibration solution, let the sensor equalize for a few more minutes and repeat Step Two. Troubleshooting If problems occur during calibration, please check the following: • Ensure that the Settings screen corresponds to the sensor being calibrated. • Check the condition of the sensor. Make sure that the electrode surfaces are not damaged, corroded, or fouled. • Make sure that the sensor is suitable for use with the MC10. Verify that the cell constant is in the correct range and that the sensor is equipped with the proper temperature element (1000-Ohm Platinum RTD). • Check the condition of the sensor wiring and that the sensor leads are properly connected to the MC10 terminals. • Verify that the calibration solution is the correct conductivity value and that the value is within the range of the conductivity input being calibrated. • Refer to the Troubleshooting Section of the manual for more information. Temperature The temperature elements in the conductivity sensors are calibrated in a similar fashion as the conductivity sensors. Follow these steps for temperature calibration.

Step One – Place the conductivity sensor in an ice bath. Allow the sensor to equalize for a few minutes. • Temperature and conductivity are combined in one sensor. • If temperature and conductivity are both being calibrated, always calibrate the temperature first. 4-2 Conductivity Being Measured by Sensor (Updates Only When "ENTER" is Pressed) Enter Value of Calibration Solution (uS) Via Keypad
