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 - fast and cost-effectively.

O2k-technical service: categories

To evaluate and diagnose technical problems, instrumental quality control tests are performed in the absence of experimental sample.

Polarographic oxygen sensors: calibration, accuracy and quality control SOP. »MiPNet06.03 POS-Calibration-SOP«

Application problems

An application problem can be diagnosed on the basis of O2k-calibration and instrumental background tests. Analysis of DatLab files recorded during instrumental tests is essential. If proper instrumental performance is obtained by resolving such application problems, any hardware problem is excluded.

Software problems

Communication between the O2k and DatLab running on a computer.

DatLab Error Message: Line has wrong length: Line has wrong length: This message appears when a signal line has not been transmitted properly from the Oxygraph-2k to DatLab. This is a problem only, if the error message appears frequently, and may indicate that the specifications of the laptop are not adequate for proper DatLab performance.

Hardware problems

Diagnostic tests are available to identify a defective instrumental component.

The two-chamber approach of the O2k provides the option to exchange parts between the two chambers and thus localize a defective component: »Locating a problem

Hardware problems that can be solved by user-service: The OroboPOS (polarographic oxygen sensor) requires user-service at intervals of more than 1 year, and SOPs are available to determine if a sensor service is required at an earlier or later date.
Hardware problems that require replacement of a defective part.
Some electronic or mechanical defects may be solved only by service of the Oxygraph-2k in the workshop of OROBOROS INSTRUMENTS, e.g. a defective Peltier unit.

DatLab Error Message: Block temperature: Average block temperature over past 10 min has not reached set temperature.

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, follow the detailed instructions.

-. Distinction between '''application problems''' and '''technical hardware problems''':
+To evaluate and diagnose technical problems, instrumental quality control tests are performed in the absence of experimental sample.
-: 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.
+* Polarographic oxygen sensors: calibration, accuracy and quality control SOP. »[[MiPNet06.03 POS-Calibration-SOP]]«
-: 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.
-. '''Technical trouble shooting'''
+=== Application problems ===
-: Localization of the '''hardware component''' causing the technical problem. Specific diagnostic tests are described under 'O2k-technical service' to identify any defective instrumental component.

+=== Software problems ===
-: The [[OroboPOS]] (polarographic oxygen sensor) requires user-service at intervals. Such user-service may solve specific technical problems.
+Communication between the O2k and DatLab running on a computer.
-: If user-service is not an option to solve the technical problem, the diagnostic tests help to take an important decision in Step 4.
+: [[DatLab Error Message: Line has wrong length]]: Line has wrong length: This message appears when a signal line has not been transmitted properly from the Oxygraph-2k to DatLab. This is a problem only, if the error message appears frequently, and may indicate that the specifications of the laptop are not adequate for proper DatLab performance.

+=== Hardware problems ===
-: 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.
+Diagnostic tests are available to identify a defective instrumental component.

-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.

+: [[DatLab Error Message: Block temperature]]: Average block temperature over past 10 min has not reached set temperature.
-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.
-* [[Biological contamination | High oxygen flux at closed chamber]].
-== How to find O2k-technical service information in Bioblast ==
