3.2 pH Electrodes & Ion Specific Electrodes (PCD5500 &
PC5500 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 isn’t 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).
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 (don’t 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.

3.3 Conductivity Probes
This meter allows you to use two types of conductivity cells: the 2-cell
conductivity cell with dual pin connector and the 4-cell conductivity
cell with DIN connector. If both a 2-cell and a 4-cell conductivity probe
are connected, the meter will read the 4-cell conductivity probe.
1. Carefully remove the protective
cover from the end of the
conductivity cell. Before using your
conductivity cell, soak it for 5 to 10
minutes in distilled or deionized
water.
2. Connect the 2-cell conductivity cell to the 2-cell jack. Install the
ATC probe in the ATC jack.
OR
Connect the 4-cell conductivity cell to the 4-cell jack. The 4-cell
conductivity cells have built in ATC probes. Therefore, there is
no need to install a separate ATC probe.

3. Rinse and blot-dry (don’t wipe)
probe between each measurement.
Rinse probe with distilled or
deionized water, or a portion of the
next solution to be measured.
4. Between measurements, store
conductivity probes dry.

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 section of the manual (page 149).

4.3 Button Functions
The touch screen of your CyberScan bench meter has “buttons”
along the right side of the screen that are common to many of the
screens. 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
dual-channel meters such as PC 5500 and PCD 5500. 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 and conductivity) as well as a setup mode.
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.
The save button allows you to save multiple changes that you
have made on one screen as a group. It functions like the enter
button does for an individual changes.
The exit button allows you to leave the screen you are
currently viewing and return to the previous screen without
making any changes.
The help button allows you to access helpful information on
any screen. When you touch the help button, information about
the current screen appears. This information will include step
by step instructions for operating the meter from the current
screen and possible applications information for that screen.
The close key appears on the bottom of all help screens and
allows you to exit the help screen and return to the previous
screen.
The more button appears on the help screens and allows you
to advance to the next help screen for additional information.
The back button appears on the help screen and allows you to
move back to a previous help screen.

This button accesses the standardization screen from the
various measurement modes and initiates standardization of
the meter once the standardization screen is accessed.
This button is the measure button and directs the meter to
measure your sample when in the Auto Read function of the
pH mode.
This button will access the setup screens for the measuring
mode that you are currently using. It can also be used to
access the system setup screen that allows you to set
parameters that are not related to measurements such as the
times and the date.
The print button will send information to the output device that
you have connected to your CyberScan meter. The output
device can be a printer, data logger or a computer. In addition
to this, touching the print button will also send data to the data
storage center of the meter if a sample ID # has been assigned
to your sample.
The arrow keys on he screen move the cursor up and down in
order to highlight parameters that you would like to review or
edit.
The edit button appears on the setup screens. After you have
highlighted a parameter that you would like to change, the edit
button allows you to access the available options for that
parameter.
The clear button allows you to remove a setup parameter or
standard buffer value from the meter’s memory that may have
been entered at a previous time or by a previous user that is no
longer of value to you. Touching the clear button erases the
value so you may enter a new one. It can also erase the data
from the memory of the meter.
The BS button is a backspace button. It appears on keypad
screens and it allows you to back up and delete a character
entered in error.
The delete button appears on the “View Stored Data” screens.
This button allows you to erase the data from the memory of
the meter.
The prev button appears on the Data Screens when the data
stored in the meter’s memory has been accessed. It allows you
to scroll through data points sorted and stored prior to the
current data point displayed.
The next button appears on the Data Screens when the data
stored in the meter’s memory has been accessed. It allows you
to scroll through data points sorted and stored prior to the
current data point displayed.
