3 GETTING STARTED

3.1 Connectors

1. Review the layout and arrangement of the rear connector panel.

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.

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).

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.

This selection screen allows you to choose the amount of information that you want to have displayed on the screen. There are two levels to choose from. Both of the levels provide identical results. The amount of information appearing on the measure screens and the number of setup parameters you can manipulate will vary from Basic to Advanced procedural levels.

LEVEL1- Basic level

This level option offers a full set of prompts to guide you through the basic operation of the meter. The information provided on the screen is minimal to reduce clutter. It includes the measurement and the last standardization time and buffer values. The data box at the bottom of the measure screen includes the current date, time, sample temperature and the electrode performance. In addition to the limited information appearing on the measure screen, there are also fewer options available to you in the setup screens of the various measurement modes.

LEVEL 2- Advanced level

This option allows you to access to all of the features available on the meter. A full set of prompts is available on virtually every screen to lead you through the operation of the meter. You are also given access to all setup parameters for the various measurement modes. Any parameter not appearing on the basic level setup screens will maintain the value previously set in the advanced level setup screens. They will not automatically default to factory default settings. This is ideal if you want to “lock” in a parameter in the Advanced Level and switch to the Basic Level so others cannot accidentally modify the parameters.

To Select Procedural Level

1. Access the select procedural level screen from the System Setup screen. The current procedural level is displayed on the screen.

2. Use the numbered buttons on the right of the screen to select the desired procedural level.

3. Touch enter to accept the procedural level and return to the System Setup screen.
