CAUTION! Ensure calibration on air before measurement.Wait approx. 2 minute until the reading value stabilizes. If the reading value on air is not within 20.7 to 21.1 (20.9 ± 0.2), then proceed with calibration procedures first. For calibration procedures, please refer chapter 5.2, page 21. After completing the calibration procedures, the display should show a value between 20.8 and 21.0 (20.9 ± 0.1).
