| The assembly of the chamber and a procedure to position the glass chamber very accurately is described in [http://www.oroboros.at/index.php?id=o2k-start MiPNet12.06].
| |
| A wrongly positioned glass chamber can lead to a huge variety of problems, some obvious but others very difficult to understand.
| |
| ==Possible Problems==
| |
| * chamber leaking liquids (medium is leaking out of the chamber)
| |
| * oxygen leak of the chamber (strongly negative intercept in the [[instrumental background test]]
| |
| * unstable O2 signal
| |
| * unexpected high or low O2 signal
| |
|
| |
| ==Trouble shooting procedure==
| |
| If the problem is obviously related to the chamber proceed to solutions. If the problem manifests in a very low or zero raw signal, the possible contribution of chamber assembly to the problem is easily checked by doing the first step of [[Locating_a_problem#Remove_components]]: if a very low or zero raw signal changes to the expected values (see [[Raw signal]] the problem is the chamber assembly.
| |
|
| |
| Otherwise follow [[Locating a problem]]
| |
| If the problem is not located on the [[POS]] or the [[POS connector]] try solving the problem by reassembling the chamber before concluding that the [[main unit]] is defect.
| |
|
| |
| ==Solutions==
| |
| * Disassemble the chamber by reversing the instructions in [[MiPNet19.18A O2k-Start]].
| |
| * Check for visible damages on the [[glass chamber]], on the [[POS seal tip]] and all o-rings (on chamber holders or on stoppers). If a damage is visible replace the part or consult OROBOROS Instruments. If there is a deposit visible in the glass chamber see [[Cleaning the glass chamber]].
| |
| * Reassemble the chamber following exactly the description in [[MiPNet19.18A O2k-Start]]. Especially, use only small increments (not more than successive quarter turns of the POS holder) when lowering the chamber.
