6.1 DO Standardization
The CyberScan DO 5000 has two standardization modes. There is
auto- standardization, merely requiring the touch of a button to
complete. There is also manual standardization. Here the DO value,
in either % Saturation or mg/L units, of the standard will be entered
manually by means of a keypad, which appears on the screen.
It is necessary to standardize the meter when the probe is in an
environment with a known concentration of oxygen. One such
environment is water-saturated air. Most commonly, this involves
placing the DO probe into a BOD bottle filled with about 1 inch of
water. Stirring is not required. Another environment is air-saturated
water, achieved by aerating 300 – 500 ml of water for at least 15
minutes. The probe can be placed into the water with stirring
provided. Lastly, the probe is placed into an environment whose
oxygen content has been determined by a Winkler titration. The
meter is standardized in the manual mode.
Prior to standardization, adequately prepare the probe as
recommended in its operation manual.
ONCE STANDARDIZATION IS SET, IT WILL BE APPLICABLE IN
OTHER MODES.

Barometer Calibration
The CyberScan DO 5000 internal barometer provides pressure
compensation for both auto and manual standardization. For most
accurate results, the barometer reading should be checked
occasionally for accuracy. If the meter’s barometer reading is
inaccurate, refer to DO setup to calibrate the barometer.

Measuring DO with Auto Read ON
The measure screen provides a readout of the current sample
measurement. If Auto Read is active, the meter will lock onto a
reading until meas is touched. If Auto Read is inactive, the meter will
continuously monitor the DO and the reading will indicate any change
in the DO level, Regardless of the status of the Auto Read mode, a
STABLE message is displayed when the measurement meets the
stability criteria chosen.
Once the meter has been standardized, you are ready to take DO
measurements.
To Measure DO with Auto Read ON
1. Insert the probe into the sample
2. Provide stirring, such as that provided by the self-stirring BOD
probe.
3. Touch meas, and permit the reading to stabilize
4. Record the reading
Prior to sample measurement, it is important to verify the salinity of
the sample and enter that’s salinity value using the DO setup menu.

To measure BOD, a sample is seeded and incubated in the dark at
20°C for five days. The dissolved oxygen concentration is then
measured and subtracted from the initial, pre-incubation, dissolved
oxygen concentration. The difference is a measure of the biochemical
oxygen demand, or BOD of the sample.

With the CyberScan DO 5000, BOD calculations are automatic.
When the BOD button is touched, a variety of meter screens will
sequentially appear, allowing you to enter information essential to a
BOD calculation. Among these are the sample description, ID
number, and date. If a search of the memory does not match the
current sample ID, the meter treats the sample’s DO reading as an
initial reading. If the sample ID is matched in the data log, and at
least one day has passed, the meter treats the sample’s DO reading
as a final reading, and based on parameters previously entered,
calculates and displays the sample BOD, along with all relevant
information.(If the sample ID is matched on the same day as the
initial DO reading, the meter will assume a new reading, and offer
information includes a sample description, sample bottle ID volume),
final dilution (ml sample: ml bottle volume), initial and final DO values,
and the average BOD value. The average is derived from all BOD
values with the same sample description and date.
Once the meter has been standardized, you are ready to measure
DO for a BOD measurement.

If, at this point, the meter matches the seed’s identification
parameters with those stored in the memory and at least one day has
passed*, it accepts the current DO measurement as a final
measurement. Using this value along with the initial DO value and
associated information, a BOD for the seed is calculated, and stored
in memory (See Viewed Stored Data). An average BOD calculated
from all seed vales on this date will be used to calculate the seed
correction value used in all subsequent sample therefore necessary
to run seed samples on the same day as the BOD samples. Seed
BOD data will be used only if the DO loss and the final DO exceed
the criteria set under the Set BOD configuration option in setup.
*If a second BOD value is taken on the same day as the first BOD
value, the meter will ask the user if he or she wants to repeat the first
BOD measurement. Touch OK to do so and overwrite the first

10 DO FUNDAMENTALS
Meter Operation
The CyberScan DO 5000 meter uses the polarographic method of
determining dissolved oxygen concentration. A voltage is maintained
across two electrodes (a gold cathode and a silver anode) and an
electrolyte separated from the sample solution by an oxygen
permeable membrane. Oxygen diffuses form the sample across the
membrane where it is reduced at the cathode.
1) 0
2
+ 2H20 + 4e- 4OH
-
The current generated, I, by such an electrode is proportional to the
oxygen concentration of the sample. The rate of oxygen reduction at
the cathode is significantly faster than the rate of diffusion to the
electrode. Therefore, the rate of oxygen reduction is diffusion limited.
2) I = k D [O2]
I is the measured current
K is a proportionally constant
D is the diffusion coefficient of oxygen
Equation 2 is a simplified description of current generated by the
oxygen electrode. Many other factors such as electrode surface area,
membrane thickness, membrane permeability coefficient,
incorporated into the constants k and D. as the partial pressure of
oxygen in the water is equal to that in the atmosphere, the electrode
output is an indicator of oxygen partial pressure. The oxygen partial
pressure differential between the sample and the electrolyte inside
the electrode is the driving force bringing oxygen to the electrode.
Oxygen Solubility
Oxygen Solubility in water is a critical parameter in many arenas
including biochemistry, industrial processes, and particularly
environmental science and engineering. Sufficient dissolved oxygen
is an absolute requirement for good water quality. It is essential for
aerobic life and the natural purification processes to which they
contribute. Dissolved oxygen concentrations below 5 ppm will result
in substantial damage to the aquatic ecosystem, and concentration
below 2 ppm can result in fish kills and growth of harmful bacteria.
