Oxygen signal: 1-Point-calibration

Place the sensor for several minutes at humid (100% water
vapour saturated) air and ensure, that there are no water
drops on the membrane.

Select in the menu „Sensors“ the oxygen sensor (O2S) and
choose „Sensor calibration/ O2 % a.s.“.

Select 100% a.s. (Calibration Point 2) to take up the 100%
a.s. calibration point. Wait the displayed 120 s and save this
point with OK.
