[. . . ] Instruction Manual CyberScan CON 1500 Bench Conductivity/ TDS/ Resistivity Meter Technology Made Easy . . . 68X292335 Rev 1 01/04 PREFACE Thank you for selecting the Eutech Instruments CyberScan CON 1500 bench meter. The instruction manual serves to explain the use of the CyberScan CON 1500 bench meter as a step-by-step operational guide to help you familiarise with the meter's features and functions. It is structured sequentially with illustration of diagrams that explains the various functions and setup menus available. This manual is written to cover as many anticipated applications and uses of the CyberScan CON 1500 bench meter as possible. [. . . ] Press the enter key to make the selection and use the /save or /view keys to toggle between NO or YES. Select YES to clear all the existing buffer values or NO if no change is to be made. save view 4. Press the enter key to confirm selection OR press std to exit from this page. Continue to access other setup pages using /save or /view keys OR press std key to exit from the setup and return to measurement mode. Depends on the measurement mode you are in, this setup page clears only the particular mode calibrated value. Suppose you access the setup pages from TDS measure mode and you choose to clear the standardised buffer then the meter only resets the TDS standardisation. Conductivity/ Resistivity standardisation if any will remain unchanged. When accessing the cell constant, temperature coefficient, TDS factor, temperature unit selection and stable ON/OFF setup pages, meter will display the last selected choice. 40 Instruction Manual CyberScan CON 1500 4. 2. 16 Setup Page 15. 0: Replatinisation Process This setup page allows you to replatinise the probe and is only applicable for 2-cell probes. Replatinisation is the process of replacing the platinum on the surfaces of the 2-cell conductivity probes that may flake or wear off over time. The platinum on the surface of the probe is used to increase the measuring surface area, resulting in decreased population error. Should the cell constant of your conductivity probe change by more than 50% from its typical value, it may be necessary to replatinise the probe. Replatinisation is a relatively quick procedure to perform, typically taking no more than 5 minutes. Although replatinisation is not a long process, the replatinisation solution is costly. 41 Instruction Manual CyberScan CON 1500 1. Access the Replatinisation Process setup page from any measurement mode screen by pressing the setup key.

Use the /save or /view keys to scroll through the options of YES and NO for the selection of replatinisation. Press the enter key to confirm selection OR press std to exit from this page. save view 6. Continue to access other setup pages using /save or /view keys OR press std key to exit from the setup and return to measurement mode. "5:00 minutes" will appear on the main display. MIN 2. Upon completion, the meter will return to the measurement mode screen. Press stdby again should you wish to enter measurement mode. 43 Instruction Manual CyberScan CON 1500 5. STANDARDISATION Conductivity probes are generally identified as having a characteristic cell constant, 0. 1, 1. 0 or 10. 0 which reflects their physical geometry and their range of application. The actual cell may vary somewhat from the nominal values, and therefore the actual cell constant must be calculated using a solution with a known conductivity value. The standardisation process of the CyberScan CON 1500 meter permits you to obtain the exact cell constant of your electrode. Prior to standardising, use the setup menu from measurement screen to set the desired units, nominal cell constant which best matches the electrode you are using, temperature coefficient desired (See Theory section, page 60), temperature units and normalised temperature and also depending on whether you want to perform a single-point or multi-point calibration. [. . . ] The meter requires no regular maintenance, but it is recommended to occasionally wipe down the front with a damp cloth.
