This instruction manual describes the operation of the meter. The state-of-art meter that you have purchased is easy to operate and will guide you through the various functions by displaying easy to understand prompts. This manual should answer any questions that might arise in operating your meter, however, do not hesitate to call our Technical Support at (65) 6778 6876 (ext 839) or fax at (65) 6773 0836. This instruction manual is designed to provide all the information necessary to guide you through the process of measuring pH or mV with a series of prompts on the screen. You will find this symbol appearing in this manual; it indicates useful tips that ease your meter operation. The CyberScan pH1500 meter provides microprocessor precision in a compact benchtop design that is easy to use. This metre allows you: Measure pH, absolute mV or relative mV Select one of three sets of standard buffer groups Standardise with up to five buffers It all adds up to rapid, completely automatic, intuitive operation. 2 Instruction Manual CyberScan pH1500 2 GETTING STARTED 2.1 Meter Overview 3 Instruction Manual CyberScan pH1500 2.2 CONNECTORS 1. Review the layout and arrangement of the rear connector panel. 4 Instruction Manual CyberScan pH1500 2. Connect the electrode arm to the base. 3. Connect the power cable to the connector cable to the rear connector panel power jack and to a power source. 5 Instruction Manual CyberScan pH1500 3 USING THE METER 3.1 Electrodes This meter allows you to use two types of electrodes: the conventional glass pH electrode and the Eutech Instruments field effect transistor (FET) pH electrode. If both types of pH electrodes are connected, the meter will read the FET electrode. 1. Carefully remove the protective cover from the end of the electrode. Before first using your glass pH electrode, or whenever the pH electrode is dry, soak it 2-4 hours in electrode storage solution, pH 4 buffer, or KCI solution. 2. Remove the shorting cap on BNC connector. Install the combination pH electrode by plugging it into the BNC input connector (Twisting to lock in place). If a combination electrode isn't used, install the indicating pH electrode into the BNC input connector. Plug the reference electrode into the reference pin jack. Also, install the ATC probe into the ATC jack. Option: install the optional FET electrode by plugging it into the FET jack on the back meter panel. Allow the Eutech Instruments electrode to warm up five minutes before use. 6 Instruction Manual CyberScan pH1500 Do not discard the BNC shorting cap. 3. Rinse and blot-dry (don't wipe) electrodes between each measurement. Rinse electrodes with distilled or deionised water, or a portion of the next solution to be measured. 4. Between measurements, store conventional pH electrodes storage solution, pH 4 buffer, or KCI solution. Always leave the filling hole of liquid filled combination electrodes open. Refill when the level of solution gets below the manufacturer's recommended level. Proper electrode care is fundamental for obtaining reliable pH measurements. Improper care of the electrode may cause the meter reading to drift, respond slowly, or produce erroneous readings. For this reason, the electrode should always be conditioned and used in accordance with manufacturer's instructions. 7 Instruction Manual CyberScan pH1500 3.2 Temperature Probe For more accurate pH measurement, a temperature probe (supplied with the meter) is used for Automatic Temperature Compensation (ATC). Once the temperature probe is connected into its socket (located at the back of meter), the ATC icon is displayed on the screen to indicate that the meter is in ATC Measure mode. If the temperature probe is not connected the meter displays 25.0 oC or 77 o F as the default temperature value. When in ATC mode, the meter allows fine offset temperature adjustment of ±5.0 oC (±9.0 oF) from mV mode by pressing the std key. Use or key to set the desired value and press enter key to confirm. The meter returns to the Measure mode. 8 Instruction Manual CyberScan pH1500 3.3 Display / Keys Overview of the meter screen display and function key layout. Press std key to initiate standardization. Or press std key at the Standardize mode allows you to exit and return to Measure mode. Press mode to select pH, mV and Relative mV. Press setup key to access setup for configuration of meter setting. Press print key to print stored data from memory or current reading to a PC or printer (depending on meter setup). Press enter key to confirm selection or change being made. Press key to increment value or scroll up selection. Press key to decrement value or scroll down selection.
