Meter package includes Meter Power adapter (120 VAC/ 12VDC) OR (220 VAC/ 12 VDC) depending on order code. Electrode arm support bracket Electrode arm ATC probe Instruction Manual If any of these items are missing, please contact your nearest Authorized Distributor. Accessory conductivity probes and ion selective electrodes are available and can be ordered by contacting any Authorized Distributor or Eutech Instruments Marketing (65) 67786876. 2 Instruction Manual CyberScan pH5500/ 5000 3 GETTING STARTED 3.1 Connectors 1. Review the layout and arrangement of the rear connector panel. 3 Instruction Manual CyberScan pH5500/ 5000 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. To connect RS232, see Data Management on Section 15.2. 4 Instruction Manual CyberScan pH5500/ 5000 3.2 pH Electrodes & Ion Specific Electrodes (Ion Specific Electrode applicable for CyberScan pH5500 only) This meter allows you to use two types of pH electrodes: the conventional glass pH electrode and the 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, soak it 2-4 hours in an electrode storage solution, pH 4 buffer, or KCI solution. 2. Remove the shorting cap on BNC connector. Connect the combination pH electrode in to the BNC input connector. If a combination electrode is not used, connect 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. Note: Be sure to connect all probes to the appropriate channel connectors (for example: Input 1, Ref 1 and ATC1). 5 Instruction Manual CyberScan pH5500/ 5000 Option: Connect the optional FET electrode by plugging it into the FET jack on the back meter panel. Allow the FET electrode to warm up five minutes before use. Connect ion specific electrodes in the same manner as pH electrodes. If both a conventional and a FET electrode are connected to the meter, do not put them in a solution together because you will get inaccurate measurements. Do not discard the BNC shorting cap. 3. Rinse and blot-dry (do not wipe) electrodes between each measurement. Rinse electrodes with distilled or deionized 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 to 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 conditional and used in accordance with manufacturer's instructions. 6 Instruction Manual CyberScan pH5500/ 5000 4 USING THE METER EUTECH INSTRUMENTS 11:11 am Touch anywhere to resume 7 Instruction Manual CyberScan pH5500/ 5000 4.1 Touch screen Operation This new CyberScan research benchtop meter operates with a state of art touch screen. The touch screen makes this the easiest meter on the market to operate and care for. When this meter is first plugged in, the STANDBY screen will appear. Touch anywhere on this screen to access the functions of the meter. The buttons on the right side of the screen control all of the functions of the meter. Alight touch on the screen is all you need to access the various functions. Once you touch a button you will get an audible tone; the screen will not change until you lift your finger. This design prevents rapid uncontrolled scrolling through the various function screens. Easy to understand prompts guide you through the operation of the meter in the selected mode. If you are ever in doubt about what to do, just touch help on the bottom right corner of the screen for detailed information about the screen. The touch screen is made of a durable polyester material that is chemically resistant. Maintenance is simple with this meter. To clean the screen you just need to wipe it with a damp cloth and dry it with a clean dry towel. For additional information, see Cleaning and Troubleshooting sections of the manual.

The following indicates the function of these common buttons. This is the standby button and it allows you to access the standby mode. When in standby, the meter will not take measurements. It is in a state of rest. When you touch stdby the meter will return to the standby screen which says "Eutech Instruments" and displays the time. This button allows you to access the channel screen to choose what channel you want to view. This button appears only on multi-channel meter such as CyberScan pH5500. This button also allows you to move from the main mode to the channel screen to access the standby mode. The mode button allows you to switch between the various operations of the meter. These operations, depending upon which meter you have, include four measuring modes (pH, mV, ion) as well as a setup mode. mode enter The enter button allows you to accept any changes that you have made on one setup screens or accept values that you have input with keypads. When touched, enter will save the changes and return you to the previous screen. save The save button allows you to save multiple changes that you have made on one screen as a group.
