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]]. '''Therefore it is of special importance to follow the guidelines for ESD protection [http://www.oroboros.at/index.php?id=esd-protection [MiPNet14.1]] whenever handling a POS connector.'''
== Functions ==
The POS 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 POS connectors for Series A-C and for Series D are NOT interchangeable.
== Technical Service ==
Nearly all problems usually associated with the [[POS]] may in fact be caused by the POS connectors, e.g.
*unstable O2 signal
*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.
