| == When should an O2-sensor test be performed? ==
| |
| * After switching on the O2k, every day: air calibration and stirrer test.
| |
| * Zero oxygen calibration: from time to time over weeks; bracketing zero oxygen calibrations when working at low oxygen.
| |
| * After application of a new membrane and O2-sensor service: In some cases, the signal of the OroboPOS improves (higher signal stability, less noise, shorter response time), when the O2k remains switched on over night (O2k-Chambers filled with 70% EtOH).
| |
| * During troubleshooting, particularly when [[switching components]] between the two chambers, a quick sensor test is performed after each step (stirrer test, sensor signal).

| == The main criteria for sensor performance ==
| |
| Β | |
| * [[Raw signal at air saturation]]
| |
| * [[Zero current |Raw signal at zero oxygen]]
| |
| * [[Signal stability]]: drift and noise
| |
| * [[Response time of the POS]]
