5. deviation Experience has shown that the Sen seAir sensors we use function without any problems for at least two years without calibration being necessary The sensors are calibrated with the highest precision during manufacture however it could occur after a year in use that the sensor shows a deviation and needs to be calibrated PREPARATION FOR CALIBRATION 1 Place the CO2 sensor in a CO2 neutral environment such as a balcony or your garden for at least half an hour or in a sealed and well ventilated room for at least 8 hours This is best done during daytime because the CO2 values will be closest to 400 ppm During nighttime plants and trees emit CO2 and the outdoor CO2 values will be closer to 450 ppm If the minimal value is not much lower than 370 ppm or much higher than 430 ppm it is not nec essary to calibrate the sensor That is because the value of neutral clean outdoor air is between 380 ppm and 420 ppm A devi ation of 5 is common with this type of measurement equipment Please keep this in mind when setting your CO2 values In case of a greater deviation calibration is necessary Please continue with step 2 2 To calibrate the sensor you have to switch DIP switch 1 see image from position 0 to position 1 ON This is to prevent any unintentional calibration caused by any electronic dimmable control gear which can cause much disturbance to our measurement equipment This manual security has been built in f
