| == 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.
| |
| | |
| :::: The OroboPOS-Connector is sensitive to damage by [[ESD]] when disconnected from the [[O2k-Main Unit]] and when the POS head is removed. Further details: [[MiPNet14.01_ESD-damage]].
| |
| | |
| == Cleaning the body of the OroboPOS-Connector ==
| |
| | |
| :::: When experimental media or electrolyte (during [[MiPNet19.18B POS-service |service of the polarographic oxygen sensor OroboPOS]]) leak into the mechanical part of the OroboPOS-Connector, operation of the spring mechanism may be restricted. In such cases, the body of the OroboPOS-Connector should be washed with distilled water. To do so, screw the OroboPOS head onto the OroboPOS-Connector. Make sure that the plug connecting to the O2k-Main Unit does not get wet (protect with parafilm). Rinse the body of the OroboPOS-Connector with distilled water, pulling the spring-loaded part at the base several times. Salt crystals and media clogging the mechanical part are thus washed out. Wipe off the water while again pulling down the spring-loaded part.
| |
| | |
| == Cleaning the electrical connections ==
| |
| | |
| ::::# Unscrew the OroboPOS and check the electrical connections (the gold pin and thread on the OroboPOS and OroboPOS-Connector).
| |
| ::::# Remove any contaminating grease and moisture with a fine paper cloth.
| |
| ::::# Moisten a paper cloth with ethanol and carefully clean the gold pin and threads. If the gold pin and thread on the OroboPOS-Connector are discolored or appear stained, clean repeatedly with a paper towel moistened with ethanol, until no more traces appear on the paper towel used for cleaning.
| |
| ::::* If the O2k is used in a humid environment, the connector can be dried in an oven at up to 60°C for 1-2h. Follow the procedure with an [[Oxygen sensor test]] as a quality control of proper OroboPOS-Connector and sensor performance.
| |
| | |
| == Replacing the OroboPOS-Connector ==
| |
| ::::If you need to replace the Orobo-POS Connector, an [[OroboPOS-Connector Service]] may be possible.
