COND CAL Method Prepare the conductivity reference solution using your normal method. Its value should be near the typical measured process value for best accuracy. When the value is relatively low (between 200 and 100,000 microSiemens/cm), the data in TABLE E on the next page can be used to prepare the reference solution.

Thoroughly rinse the clean sensor in de-ionized water. Then immerse the sensor in the prepared reference solution. Important: Allow the sensor and solution temperatures to equalize. Depending on their temperature differences, this may take up to 30 minutes. NOTE: Suspend the sensor to prevent it from touching the container. Simply laying it into the container will produce calibration error.
