1. INTRODUCTION
Thank you for selecting a Eutech Instruments CyberScan Dissolved
Oxygen 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 meter is designed to provide all the information necessary to
guide the user through the process of measuring dissolved oxygen
with a series of prompts on the screen.
The CyberScan DO 1500 provides microprocessor precision in a
compact benchtop design that’s easy to use. Seven function keys
control all procedures.
It all adds up to rapid, completely automatic, intuitive operation.
)
You will find this symbol appearing in this manual; it indicates useful
tips that ease your meter operation.

2. GETTING STARTED
2.1. Connectors
1. Review the layout and arrangement of the rear connector panel.
2. Connect the power adapter’s output power jack to the meter’s
rear panel DC input power socket and plug in the adapter to a
power source.
)
Make sure the power adapter centre is negative.

3. USING THE METER
3.1. The Electrode
This meter comes equipped with a self-stirring BOD probe, model
5010, from YSI. Read the accompanying manual prior to installation
and operation. The 5010 probe need be plugged into the meter only,
as the meter supplies both its operation power and stirring power.
1. Prepare the electrode as described in its instruction manual.
2. Plug the electrode into the DO jack on the back meter panel.
3. Place the probe into a BOD bottle filled with at least 1 inch of
water. Allow the probe to warm up for 30 minutes before
calibration or taking a measurement.

Instruction Manual CyberScan DO 1500
8. DO THEORY
The polarographic type Oxygen probe used with the CyberScan DO
1500 meter responds to the partial pressure exerted by oxygen in a
given sample. As Oxygen reaches the probe's cathode, it is reduced
according to the following equation:
+ 2 H2O + 4e- = 4 OH-
O
2
When oxygen is reduced at the cathode (along with concurrent
oxidation of silver at the anode) current flows through the cell. The
more oxygen that is reduced, the more current is generated. The
relationship is linear, and by measuring the current generated in a
sample, and comparing it to that of a standard, one can compute the
amount of oxygen in the sample.
The primary influence on how much oxygen reaches the anode is the
partial pressure exerted by oxygen on the probes’ membrane. More
partial pressure brings more oxygen, and therefore more current. The
partial pressure that oxygen exerts is fixed for a given temperature
and atmospheric pressure. This fixed level corresponds to the
saturation level for a given temperature and pressure. The
CyberScan DO1500 meter uses the known relationship between
these parameters to permit simple, automatic standardisation.
In sample measurements, however, another factor influences the
relationship among partial pressure, temperature, and dissolved
oxygen. This is the factor of how much salt is contained or dissolved
in the sample. The presence of dissolved salt lowers the sample’s
ability to dissolve oxygen. Therefore a sample with a high level of
dissolved salt will contain less oxygen than a sample with less or no
salt at the same temperature and pressure. Fortunately, the
relationship between dissolved salt or salinity and dissolved oxygen is
well defined. The CyberScan DO 1500 uses this fact to provide
accurate dissolved oxygen measurements in samples whose salinity
range from 0 to 45 ppt.
