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.

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.

It is a well known fact that pH is a temperature dependent measurement. The factory default setting is 25. if you are taking the pH of a solution that is not 25 and you are not using an Automatic Temperature Compensation (ATC)( probe, then you should meter the temperature value of that solution in order to get the correct pH value. The current default temperature setting will be displayed when the Set Default Temperature screen is displayed.

To Set the Default Temperature

1. Access the Set Default Temperature screen from the pH (ion) Setup screen. The current default temperature is displayed on the screen.

2. Touch clear to erase the current temperature value.

The Isopotential point is the millivolts reading for an electrode at which temperature has no effect on the measurement. pH electrodes are constructed so that the isopotential point is theoretically zero millivolts. This is very close to a pH of 7. Most pH electrodes do not achieve this value precisely. However, they are close enough so that it is not usually necessary to use an isopotential point other than zero. The true isopotential point of any given electrode must be determined experimentally. (See appendix: Determining Isopotential Points Experimentally, pg 124)

Instruction Manual CyberScan pH5500/ 5000

Direct Reading with Standards

The direct reading method is the most common method of ion measurement. When using this method, you will use standards of known values to standardize the meter with ion standards. An ionic strength adjuster (ISA) is added to both the standards and the sample. 2 to 5 standards are used to standardize the meter. The standards should bracket the expected value of the sample. The Ion specific electrode is immersed in a stirring sample and the ion concentration is read directly from the meter.

Direct Reading with Blank offset

The blank method is a method commonly used for determination of ion concentration in a sample with a very low level of ions present. Because of background interference at low concentration levels, a blank is used and the value of the ion concentration in the blank is subtracted from the value of the measured sample.

Known Addition Method

The known addition method is an incremental method used for samples with a complex matrix. A standard with a known concentration of the ion species of interest is added to the sample. The difference in mV potential is then used to calculate the concentration of the ion of interest.

Known Subtraction Method

The known subtraction method is also an incremental method. The ion of interest in the sample is not identical to the ion in the standard solution. The standard of known ion concentration that is added to the sample quantitatively reacts in the sample with the ion of interest. This reaction removes a fixed amount of the ion of interest from the sample solution. The ion concentration is then calculated based upon the difference in the mV potential.

Analate addition

The analate addition method is a modification of the known addition method. In the Analate Addition method, the initial mV measurement is recorded in a standard solution. The ion in the standard solution is the ion of interest and is detected by the ion selective electrode in use. A sample containing the ion of interest is then added to the standard solution. The difference in the mV potential is then used in the calculation of the concentration of the ion of interest. This method is useful if the sample temperature is significantly different than that of the standard. When the small volume of hot sample is added to the larger volume, the temperature impact becomes negligible.

84

Instruction Manual CyberScan pH5500/ 5000

Analate Subtraction

The analate subtraction method is particularly useful in the event that there is no ion specific electrode available to directly measure the concentration of the ion of interest. This method employs the addition of a sample of the ion of interest to a standard containing a different ion of known concentration. The ion of interest will quantitatively react with the ion in the standard, creating a complex and removing the ion from the standard solution. The ion specific electrode is specific for the ion in the standard solution and not for the ion of interest. The difference in mV potential is used to calculate the concentration of the ion of interest based upon this quantitative reaction.

8.3 Select Measurement Units

This screen allows you to select the units in which the meter will report the concentration of the ion of interest. The current units are displayed on the screen.

To Select Measurement Units

1. Access the Select Measurement Units screen from the Ion Setup screen. The current units are displayed on the screen.

To Select Auto Read Mode

You can use this meter when the Auto Read Mode function is active or when it is inactive. When the Auto Read function is active, the meter will lock onto a reading when the meter recognizes it as stable. The meter will not deviate from this reading until meas is touched. If the auto Read function is inactive, then the meter will continuously monitor the concentration of the ion of interest. The display on the measure screen display will indicate any fluctuation in the ion concentration.

The Ion sample ID# is set the same way as previously described in pH Setup. See page 41 for instructions.

To Set Ion Stability Criteria

The setup screen allows you to determine how quickly the meter will respond to electrode drift. There are 3 speed settings.

The Ion Stability Criteria is set the same way as previously described in pH Setup. See page 51 for instructions.

To Set Default Temperature

Ion concentration is a temperature dependent measurement. The default temperature option allows you to select the temperature that will be used by the meter to calculate the correct ion concentration. The factory default setting is 25°C. You should enter the temperature value of that solution as the default temperature in order to get the correct concentration value. The current default temperature setting will be displayed when the Set Default Temperature screen is displayed.

The Ion Default Temperature is set the same way as previously described in pH setup. See page 53 for instructions.



Regardless of the status of the Auto Read Mode, STABLE will be displayed as the meter recognizes the measurement as stable.



Stability criteria are more stringent at the slower setting. Therefore, if the highest precision is required, then a slow setting would be desired. The medium or slow setting is recommended for Ion work.



Best results are obtained when the standards and the samples are at the same temperature.

8.4 Select Electrode Type

This screen allows you to select the type of electrode that is specific for your ion of interest. Your choice of electrode informs the meter which default slope to use in the calculations made for the electrode efficiency and sample concentration. Once you have selected an electrode, you will not be required to enter the default slope numerically.

Note: The default slope value specific for the electrode that you choose is a theoretical slope value that is used in the calculations to determine the efficiency of your electrode. This slope value is not the slope value that is displayed in the data box of the measurement screen. You will still need to standardize the meter using ion standards to determine the actual efficiency of your electrode.

To Select Electrode Type

1. Access the Select Electrode Type screen from the Ion Setup screen. The current units are displayed on the screen.

2. Use the arrow keys to highlight the desired units.

To Set Isopotential point

The Isopotential point is the millivolts reading for an electrode at which temperature has no effect on the measurement. Ion selective electrodes, unlike pH electrodes, are not designed to achieve any particular isopotential point. If samples and standards are at different temperatures when performing ISE experiments, it will be necessary to experimentally determine the isopotential point of your own Ion Specific Electrode.

The Ion Isopotential Point is set the same way as previously described in pH setup. See page 55 for instructions.

To Set Alarm Limits

This option allows you to set alarm limits for the Ion measuring mode. If the ion concentration measurement is outside the boundaries set by the minimum and maximum limits, an audible alarm and/ or a visual warning will appear to let you know that your sample measurement was outside of the set limits.

Instruction Manual CyberScan pH5500/ 5000

In this mode, you will able to measure the pH of a wide variety of samples. Before measuring pH, you will need to standardize the meter using buffers with known pH values. It is good practice to standardize the meter frequently using a minimum of two buffers. Using two buffers allows the meter to calculate and display an actual slope for the electrode, and therefore produce more accurate measurements. If there is no standardization in the memory of the meter or only one buffer has been used to standardize the meter, the slope value will appear as “NA”.

You can standardize your meter using automatic or manual buffer recognition. With the Automatic buffer recognition activated, the meter will automatically recognize the buffers from the chosen buffer group and accept them when the meter recognizes the reading as stable. When in manual buffer recognition mode, you must enter the buffer value during the standardization procedure. The meter will accept the manually entered buffer when it recognizes that the measurement is stable. During the standardization procedure, you may accept the buffer value before the meter recognizes it as stable by touching std.

See page 47-48 to select desired buffer recognition. At the basic procedural level the only setup options that you can

access are the buffer groups, the print interval and the display resolution. If you need to change any other parameter such as Buffer Recognition or Auto Read mode you will need to set the Procedural level to Advanced in the system setup screen. Any values previously saved in the pH setup screen of the advanced procedural level will become the default values for basic procedural level.

Remember to setup your pH measuring mode parameters. Refer to page 38 for pH setup instructions.

Connect the electrodes you will be using to the meter. See page 3 for details.

To Standardize the meter with Auto Buffer Recognition

1. Touch STD on the pH measure screen to access the standardized screen

2. Touch clear to delete a previous standardization. All pH standardization values will be cleared. The meter will remain on the standardization screen at this point.

OR

If the screen says “Not standardized” proceed to step 3.

3. Immerse your rinsed electrode (s) in a buffer solution from the selected buffer group that you chose during the setup process (see page 47) and stir gently.

4. Touch std again to standardize the meter using this buffer. The word MEASURING will flash until the signal is stable. The meter will accept the value once it recognizes that the reading is stable. At that time, STABLE will appear on the screen at this time. A beaker icon and the entered pH value will also appear on the screen at this time. The meter will then return to the measure screen.

5. Touch std on the pH measure screen to access the standardization screen and repeat steps 3 through 5 to standardize with up to 5 buffers.

Updating a standardization with Auto Buffer Recognition You can update a standardization at anytime. To update a

standardization, place your electrode in any of the buffers originally used to standardize the meter and touch std on the touch screen twice. The value for that buffer will be updated and stored in the meter’s memory. The time of standardization will also be updated on the pH measurement screen.

The efficiency of the electrode is reported as the slope. When doing a multi-point standardization, the slopes of the individual segment are calculated by the meter. The slope that appears on the screen is the slope that is the least perfect, or the farthest from 100%.



For optimal results, the meter should be standardized at a minimum of every 8 hours. For more accurate measurements, the meter should be standardized more frequently.
