4. surement 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 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 1V1 2 EN 26 10 2015 16 27 50
