1 INTRODUCTION
1.1 Introducing the CyberScan Series
Thank you for selecting the Eutech Instruments CyberScan pH1500
bench-top meter. 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.

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.

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.

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
oF 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.

4 SETUP MENUS
4.1 Using the Meter
The setup button brings you to the setup menus of the various
parameters. Press setup while in measurement OR standardization
to access to the setup menus. The ▲and ▼keys allow you to
change several operating parameters. While in the setup mode you
may:
Press the std key at any time to return to the
Measure screen without making a change or
selection in the setup mode. Note new change will
not be effected as no confirmation is done.
Press the setup key anytime to access the setup
mode in the measurement mode. The menu
displays the first setup menu P1.0.
Press the enter key to accept a change or
selection of desired option in the displayed
parameter. The meter will then return to the next
setup
Press the ▲and ▼keys to scroll through
(increment and decrement setup menu
respectively) the remaining selection options
available.
