OXY-1 ST (Trace)

Preface

1 Preface

You have chosen a new, innovative technology for measuring oxygen.

The OXY-1 ST (Trace) is a compact fiber optic oxygen meter. It is based on a novel technology, which creates very stable, internally referenced measured values. This allows a more flexible use of oxygen sensors in various fields of interest.

Optical oxygen sensors (also called optrodes) have several important features:

They are small. Their signal does not depend on the flow rate of the sample. They can be physically divided from the measuring system which allows a non-

invasive measurement. They can be used in disposables. Microsensors allow measurements with high spatial resolution whenever this is

required.

Therefore, they are ideally suited for the examination of small sample volumes, for highly parallelized measurements in disposables, and for biotechnological applications. A set of different oxygen mini- and microsensors, flow-through cells and non-invasive sensors is available to make sure you have the sensor which matches your application. Please feel free to contact our service team to find the best solution for your application.

PLEASE READ THE FOLLOWING INSTRUCTIONS CAREFULLY BEFORE WORKING WITH THIS DEVICE. WHEN DISREGARDING THESE INSTRUCTIONS THE SAFETY OF THE DEVICE CAN BE IMPAIRED.

Safety Notes

2 Safety Notes

! It is the customer’s responsibility to validate the sensor and transmitter under end-user

conditions according to safety precautions of the application to ensure that the use of the sensor is safe and suitable for the intended purpose.

PreSens is explicitly not liable for direct or indirect losses caused by the application of these measurement systems. In particular it has to be considered that malfunctions can occur due to the naturally limited lifetime of the sensor depending on the respective application. The setup of backup measurement stations is recommended when using the sensors in critical applications to avoid consequential losses. It is the customer’s responsibility to install a suitable safety system in the event of sensor failure.

Set-Up

3 Set-Up

1. Remove the protective cap from the male plug on the optical fiber and insert it in the ST

connector of the OXY-1 ST. The ST plug has to be inserted and slightly turned clockwise to fasten it. Be careful not to snap off the optical fiber; best hold the fiber between forefinger and thumb at the bayonet lock of the male plug.

For further information on sensor handling and calibration please refer to the respective sensor instruction manual (www.presens.de/manuals).

2. Connect the USB cable to the connector on the OXY-1 ST and to an USB port of your PC

/ notebook.

3. If required, you can now connect a Pt100 temperature sensor to the device. There is a red

mark on the temperature sensor connector of the OXY-1 ST as well as on the temperature sensor plug. Match those two marks before inserting the temperature sensor plug into the connector on the device, else the plug might get damaged.

Set-Up

4. Now start the PreSens Measurement Studio (PMS2) software on your PC / notebook.

(The OXY-1 ST always has to be connected via USB before the software is started.) After successful initialization the software main screen is displayed and the OXY-1 ST will show in the Device section.

For further details on how to use the PreSens Measurement Studio please refer to the software instruction manual.

Important Considerations for USB Handling

! PreSens recommends the use of a dedicated USB 2.0 PCI Card to connect and

handle USB PreSens Devices with a Desktop PC.

! In order to enhance the system stability avoid the use of USB hubs and connect

PreSens Devices directly to your PC / notebook USB Ports.

! If possible, disconnect all other USB devices that are not in use, as they may reduce

or disturb the USB resources of your PC / notebook.

! Docking stations may also reduce or disturb the USB resources of your PC / notebook

and therefore affect the correct function of the software.

! It is also recommended to disable the Power Saving Settings of your USB Root

controller.

Operational Notes

5 Operational Notes

5.1 Optical Output

The ST connector is a high precision optical component. Please keep it clean and dry. Always use the rubber cap to close the output when not in use.

5.2 Maintenance

The transmitter is maintenance-free. The housing should be cleaned with a cloth only. Avoid any moisture entering the housing. Never use benzine, acetone, alcohol or any other organic solvents. The ST fiber connector of the sensor can be cleaned with lint-free cloth or a cleaning implement for ST connectors only.
