O2k-technical service helps users of the OROBOROS Oxygraph-2k to localize and resolve technical problems encountered in high-resolution respirometry and O2k-MultiSensor applications. in a very fast and cost-effective approach.
O2k-technical service: categories
1. Distinction between application problems and technical hardware problems:
- An application problem can frequently be diagnosed on the basis of analysis of DatLab files recorded during O2k-calibration and instrumental background tests. By resolving such application problems, proper instrumental performance is obtained and a hardware problem is then excluded.
- If an application problem or software problem (DatLab) can be excluded, the instrumental component causing the technical hardware problem has to be localized in Step 2.
2. Technical trouble shooting
- Localization of the hardware component causing the technical problem. Specific diagnostic tests are described under 'O2k-technical service' to identify any defective instrumental component.
3. Distinction between hardware problems that can be solved by user-service and hardware problems that require replacement of a defective part:
- The OroboPOS (polarographic oxygen sensor) requires user-service at intervals. Such user-service may solve specific technical problems.
- If user-service is not an option to solve the technical problem, the diagnostic tests help to take an important decision in Step 4.
4. Distinction between hardware defects which can be solved by replacement of a defective spare part in contrast to electronic or mechanical problems which can be solved only by service of the Oxygraph-2k in the workshop of OROBOROS INSTRUMENTS.
- Some specific potential problems, e.g. a non-functioning Peltier unit, can be detected directly by a single observation followed by specific instructions for this case, which then can be solved only by electronic service of the Oxygraph-2k in the OROBOROS workshop.
It is best to follow a general trouble shooting procedure, relating to a large variety of apparent technical problems. This is especially true for problems that may have different causes or are vague in their description. For example, "unstable signal", "no signal", "slow response" fall within this category. The general O2k-technical service process described below helps to locate most hardware problems.
General O2k-service
To evaluate and diagnose hardware problems, instrumental tests are performed in the absence of any experimental sample, using an aqueous medium for which any microbiological contamination can be excluded. Experimental test runs containing a biological sample is generally not suitable for technical troubleshooting.
- Perform an OroboPOS Sensor test and analyze its results.
- Locate the problem utilizing the two-chamber approach of the O2k by strictly following the procedure described on the Locating a problem page. This also involves several more POS sensor tests.
Specific problems that do not require a sensor test
DatLab error messages
- DatLab Error Message: Block temperature: ERROR: Average block temperature over past 10 min has not reached set temperature.
- DatLab Error Message: Line has wrong length: ERROR: Line has wrong length: This message appears when a signal line has not been transmitted properly from the Oxygraph-2k to DatLab.
Other problems that do not require an oxygen sensor test
- Problems related only to the pX channel or the additional amperometric channel.
- Jumping or blocked stirring bar.
- High oxygen flux at closed chamber.
How to find O2k-technical service information in Bioblast
- You can use the standard Wiki search function in the right upper corner of most pages.
- Pages in the O2k-Catalogue will frequentyl include a list of technical service pages related to the described component.
- Use the list below to locate pages relevant to your problem.
Cost estimation for repair
A cost estimation for repair of the O2k-Main unit due to an electronic/mechanical defect can only be given after inspection of the O2k by our workshop in Austria. Once a cost estimation has been provided, the repair is carried out after the customer’s consent. For shipment of the O2k, please refer to the detailed shipping instructions on this O2k-technical service page.
