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.
OR
Touch exit to return to the System Setup screen, without making
any changes.
