My Divesoft analyser seems to give wrong measurement even after 3 point calibration. But sometimes it seems to be OK again. So I do not trust the O2 sensor anymore although it is only 15 month old.
In the Divesoft Liberty rebreather you can check the sensors by making an overpressure chamber out of the head. In a analyser this does not work. Is there any easy way to put the sensor in an overpressure situation and measure pO2 of 2 or 3 bar?
My idea is the same as Divesoft has for the rebreather: if sensor is working fine at 3 bar it will work fine at 1 bar. If sensor is working fine at 1 bar but not fine anymore at 1.5 bar then I can expect the sensor to fail at 1 bar within a short time.
