OroboPOS-Connector

Description	OroboPOS-Connector (blue POM), with male connection to OroboPOS sensor head (POS) and with cable and male plug fitting into O2k-Main Unit. Two units of this item are standard components of the O2k-Assembly Kit (O2k-Core), mounted on the OroboPOS-Holders at the O2k-Main Unit.

The two electronic connections of the POS connector (to the POS and to the Main unit) make a POS connector that has been disconnected from the POS or from the Main unit or from both particular sensitive to damage by ESD. Follow the guidelines for ESD protection MiPNet14.01_ESD_Damage when handling an OroboPOS-Connector.

Functions

The OroboPOS-Connector has several different functions:

It mechanically presses the POS against the glass chamber, ensuring a tight fit.
It connects the POS electronically to the main unit transmitting the signal.
In O2k Series A-C it also performs the current to voltage conversion / amplification. For Series D and upwards this function has been incorporated into the Main unit. For this reason OroboPOS connectors for Series A-C and for Series D are NOT interchangeable.

Cleaning the spring mechanism

MitoPedia O2k and high-resolution respirometry: O2k-Open Support

Media outside the chamber or other spills may get into the mechanical part of the POS connector restricting the operation of the spring mechanism hard. The outside of the POS connector should therefore be cleaned with pure water from time to time. Apply a POS to the POS connector and make sure its seal (to the connector) is tight. Leave the POS connector att ched to the O2k-Main Unit or make sure that the plug, which connects the POS connector to the O2k-Main Unit, does not get wet (parafilm, or some other form of shielding). This will ensure that only the outside of the POS connector becomes wet. Then rinse the blue plastic of the connector with pure water, working the spring loaded holder several times (similarly to when inserting the connector into the chamber). This will dissolve any media stuck in the mechanical part of the POS connector.

-*unstable O2 flux
-*high O2 signal at air saturation
-*high O2 signal at zero oxygen
-=== Troubleshooting procedure ===
-Confirm the problem by doing a [[Sensor test]] in the absence of biological material
-If no no problem was visible in the [[Sensor test]] check the following [[DatLab]] settings:
-* [[Gain (O2 channel)]]
-* [[POS calibration]]
-* Scaling
-If the problem is not visible when observing the [[Raw signal]] but is visible when observing the calibrated oxygen signal, then there is probable a problem with the [[POS calibration]].
-If the problem was visible in the [[Sensor test]]:
-* Proceed to [[ Locating a problem|Locate the Problem ]]
-* If thereby the problem was confirmed to be caused the OroboPOS-Connector: Follow the instructions for cleaning and applying [[contact oil]] as described in the sensor service manual [http://www.oroboros.at/index.php?id=o2k-pos-service [MiPNet08.04]] and in more detail at [[Cleaning the POS connector]]. If you have also done a [[Sensor service]] or changed the [[POS membranes]] allow the oxygraph to run over night before repeating the [[Sensor test]]. If all service precautions fail to solve the problem, or a new POS connector has to be applied.
-* If the problem was localized on an other component follow the instructions for this component. If you could not locate the problem contact OROBOROS Instruments.
