[. . . ] If the conductivity reading of the solution is beyond the selected measuring range, calibration error occurs; LCD displays "Or" (over range), "ERR" and flashes electrode annunciator. If calibration error occurs, exit form calibration mode by pressing and keys simultaneously. 4 Calibration is completed. This serves as an indication of the effectiveness of the sensor which will degrade with time and usage. An effective sensor should have a calibration factor of 0. 60 to 1. 40 Press ENT key to return to measurement mode. NOTES: · If you use a 2-cell conductivity sensor, make sure that the pin 1 and 2 are shorted and pin 3 and 4 are shorted on the J10 connector. (Refer section 2 for more details) When calibrating with manual temperature compensation, the controller automatically changes from the preset process temperature to the calibration temperature. After leaving the Calibration mode, the controller switches back to the process temperature (for setting the calibration temperature and the process temperature, see section 5. 3) · WARNING: If you change the measuring range of the controller after calibration is done, the controller will reset back to its factory default calibration. 5 5. 1 SETUP MODE Enter Setup mode The setup mode allows you to customize the settings of the conductivity controller to suite your requirements. LCD shows `SETUP' mode indicator and the first page of setup (rAng ­ Range settings). Press or key to access other pages of the setup mode.

The controller returns to the measurement mode · If you do not press any key for 2. 5 minutes, the controller automatically exists from the setup mode. 5. 2 Temperature Coefficient Settings Setting the temperature coefficient to match your process/calibration liquids allows controller to achieve conductivity readings with higher accuracy. 1 SETUP HOLD 2 ENT SETUP HOLD 3 SETUP SETUP % HOLD 4 ENT HOLD % ENT ENT 2 SETUP ENT HOLD 1 2 3 4 From measurement mode press ENT key to enter setup mode as described in section 5. 1. Press or key to select temperature coefficient settings screen (tC). Select type of temperature coefficient: The upper display shows the last configured temperature coefficient type (Lin or PUr). Press or key to select the desired type based on type of your process liquid. PUr : Pure water temperature coefficient: Select this if your process liquid is pure water or ultra pure water. Lin : Linear temperature coefficient: Select this for all other process liquids Press ENT key to confirm your selection. If PUr was selected: The controller reverts back to tC screen If Lin was selected: Select temperature coefficient for process liquid: The lower display shows `P. tC'. The upper display shows last configured temperature coefficient for process liquid (if any). Select temperature coefficient for calibration liquid: The lower display shows `C. tC'. The upper display shows last configured temperature coefficient for calibration liquid (if any). The controller reverts to tC screen. Press or key to access other setup screens or press and key simultaneously (escape) to return to measurement mode. 5. 3 Temperature Settings Automatic Temperature Compensation (ATC): The conductivity value of a sample is affected by temperature. Use ATC feature of the controller to compensate for conductivity changes when the temperature of the sample or process liquid fluctuates. Connect a separate temperature probe (Pt100/pt1000) to the controller if an integrated conductivity/Temperature probe is not available. Manual Temperature Compensation (MTC): Set the controller to MTC (disable ATC) when the temperature of sample or process liquid is constant and a temperature probe is not available.
