3. more than 10 minutes turning on check the analog output through the extending wires to avoid influence of breathing process on CO concentration 2 CD 2V1 2 EN 26 10 2015 16 40 06
4. s proved to be incorrect by comparing with the measurement of other CO sensors or put the sensor outdoors and its measurement is away from the range of 350ppm 450ppm which is the normal ambient CO concentration then let the self calibration system work as follows Keep the CO sensor energized continuously for at least 2 days to let CO sensor s self calibration system operate properly After more than 2 days calibration if the measurement indicated by the analog output of the CO sensor still exceeds over the accuracy you need to let it self calibrated for a longer time Here s a typical 14 day calibration solution During a 14 day period place the CO sensor twice outdoors or in unoccupied places where CO level is around 400 ppm Each time let it be there for more than 4 hours and then check the CO measurement via analogue output If the CO measurement is in its accuracy limit it indicates the measurement is correct Notice a Using of cellular telephones or radio transceivers about 60 cm away from the sensor during calibration process could cause sensor interference calibration errors and affect sensor accuracy Please refrain from using these devices during calibration of the sensor b When checking the analog output please avoid breathing out directly to the CO sensor It s recommended to connect the output terminals with the extending wires with length of more than 1 meter When the CO sensor indications become stable after
