Installing and Maintaining Electrodes
1. Remove the protective end cover
from electrode.
2. Before using your pH electrode, or
whenever the electrode is dry, soak
over-night in an electrode filling
solution, KCI solution or electrode
storage solution.
3. Remove the shorting cap on the
BNC connector. Install the electrode
by plugging it into the input con-
nection (push on and twist to lock).
An accessory ATC probe can be
installed in the ATC port for the
most accurate measurement.
If a separate reference electrode is
used, plug the reference electrode
into the ref pin.
4. Rinse and blot-dry electrodes
between each measurement
(do not wipe). Rinse electrodes
with distilled water or deionized
water, or part of the next solution
to be measured.
5. Store pH electrodes in KCI solution
or electrode storage solution.
Always leave the filling hole open
when in use and closed when in
storage. Refill with filling solution
when the internal solution level
drops to 1”below fill hole.
Note: The electrode that comes
with the UltraBasic kit is gel-filled.
It has no filling solution or filling
hole.

11
Standardizing for pH Measurement
Because electrodes vary in their response, you
must standardize your pH meter and electrode
to compensate for electrode variation. The more
frequently you standardize, the more accurate your
measurements. We recommend standardizing at
least once a day for best results.
Note: To exit the standardizing mode,
press “Standardize“key again.
1. Immerse electrode in a buffer solution.
Stir gently. Allow the electrode to reach
a stable value.
2. Press and release the mode button until the
display indicates pH mode.
3. Clear existing buffers when performing a new
standardization. Use the setup and enter
buttons to clear existing buffers.
4. Press standardize. The meter flashes the current
buffer set and detects the flashing buffer. When
the signal is stable, or when you press enter,
the buffer is stored.
5. The meter displays the percent slope of
the electrode as 100.0% on the first buffer.
On entering a second or third buffer, the meter
performs a diagnostic check on the electrode
and displays the slope.
6. To enter a second buffer, place the electrode in
the second buffer solution, stir, allow time for the
electrode to stabilize, and press standardize
again. The meter detects the buffer.

7. Next, the meter performs a diagnostic test of
the electrode. The display indicates electrode
condition. The meter displays the % slope of
the electrode.
8. Error displayed with the Slope symbol indicates
that your electrode is not working properly.
The electrode response must be between
90 and 105% slope. Measurements causing
Slope Error are not accepted, used or stored
by the meter. Press enter to continue.
9. To enter a third standard, place the electrode in
the third buffer solution, stir, allow to stabilize,
and press standardize. The results will be the
same as in steps 7 and 8.
10. After entering each buffer, the Standardizing
symbol goes off and the Measuring or Stable
symbol appears on the display to indicate that
the meter has returned to Measuring operation.
11. Standardize your meter and electrode using
at least two buffers with pH values above and
below the expected pH of your samples.
Stirring with a magnetic stir bar and stirrer
provides faster electrode response.
Note: If an ATC probe is used, the meter continually
adjusts for temperature. Therefore, buffers
may vary slightly from the nominal values due
to temperature factors.
Default temperature is 25°C
Note: The temperature is displayed only if an
ATC probe is attached.

Using Setup in pH Mode
The setup button lets you clear all the buffers/
standards that you have entered, review calibration
information, or select the buffer/standard set that
you want.
Note: Continuing to press setup will return you
to measurement mode.
1. Press setup and the meter displays a flashing
Clear icon. Continue with this step only if you
wish to clear all buffers you have entered.
To clear all existing buffers, press enter.
The meter clears all buffers and returns to the
Measuring screen.
2. Press setup again to show electrode perform-
ance. If two buffers have been stored, the meted
displays Good Electrode, display the slope
between the first and second buffers and display
the two buffer icons.
3. Pressing setup again shows the electrode
slope between the second and third buffers
(if three buffers have been entered) and
shows the second and third buffer icons.
Note: These screens will only be displayed if
buffers are stored.
4. Press setup again to display a flashing Set
Buffers icon and to display the first buffer set
(U.S. buffer series) icons.
5. Press enter to select the set of buffers shown
on the display
or
Press setup again to view the next set of buffers
(Merck buffer set). Continue pressing Setup
to view the third buffer set (NIST buffer set).

Standardizing for Millivolt Measurement/
Relative Millivolts (UB-10 Model Only)
Millivolt measurement is used for electrode
diagnostics, titration or measuring redox potential
(also called ORP, oxidation/reduction potential).
ORP measurements indicate the oxidizing or
reducing capability of a solution. You can use ORP
values to monitor or control solutions requiring
a set amount of oxidants or reductants.
1. Immerse electrode in a standard solution.
2. Press the mode button until the display indicates
mV mode.
3. Press standardize to enter a mV standard
and read relative mV.
4. When the signal stabilizes, or when you press
enter, the current absolute mV value becomes
zero relative millivolts.

The meter returns to absolute mV mode.

Troubleshooting
1. If the signal from the electrode is out of range,
the display will show “- - -”. This may indicate
that the electrode is not in a solution.
2. If the meter detects an error in the temperature
probe, the display shows “- - -”. If you do not use
a temperature probe, the meter uses the default
temperature of 25°C.
3. The meter will display Electrode Error when it
detects an error in electrode response. During
standardization, the message indicates that the
electrode is less than 90% or more than 105%
of the correct response. The Electrode Error
message can indicate either a bad electrode
or bad buffer(s).
4. To test the pH electrode, place it in a good pH 7
buffer. Press mode to use the mV mode, and
note the millivolt reading. Make sure the meter
is in mV mode and not relative mV mode. Repeat
for either a pH 4 or pH 10 buffer. The electrode
signal must be within the limits shown below
(when temperature is near 25°C).
5. To test the meter for correct operation, install
the BNC (input) shorting cap. Press mode to
select the mV mode, and note the mV reading.
Make sure the meter is in mV mode and not
relative mV mode.If the meter reads 0 + 0.3 mV,
it is measuring correctly. Note that a long term
drift of 0.1 mV/month since the last calibration is
specified.
