NB! Aranet4 is not impact resistant. Do not leave the device in the direct sunlight.
1
CO
2
sensor of the device is calibrated at standard atmospheric pressure. CO
2
readings are pressure compensated and comply with the
specifications down to 750 hPa. If the device has to be used at high altitude for a prolonged period of time, manual calibration of the unit should be
performed for optimal performance. It is not intended to use the device higher than 4000 m (13 000 ft) above the sea level.
2
The device measures absolute pressure, i.e., pressure readings are not compensated for an elevation above the sea level.
3
95 % of the sensors measure within these typical limits in equilibrium state at the time of sale. For evaluation of the total measurement error long-
term drift has to be taken into account.
4
CO
2
measurement accuracy is provided for a range 0 … 5000 ppm, temperature 15 … 35 °C (59 … 95 °F) and relative humidity 0 … 80 %. Accuracy
above 5000 ppm is 10 % of reading, but not guaranteed since it is extrapolated form the calibrated range.
5
If a drift of the CO
2
measurements occurs, calibration feature of the device should be used. Auto calibration mode is utilizing ABC algorithm whereas
Manual calibration mode demands sensor to be exposed to fresh air.
6
Time constant is determined at 1 m/s airflow.
