3. N Do not calibrate the meter in an atmosphere of unknown CO2 concentration ABC Automatic Baseline Calibration ABC Automatic Baseline Calibration establishes a baseline calibration to eliminate the zero drift of the infrared sensor The ABC function is always ON when the meter is turned on ABC is designed to calibrate the meter at the minimum CO2 reading detected during 7 5 days continuous monitoring power on It assumes that the area being tested receives fresh air with a CO2 level of approximately 400ppm at some period of time during the seven days It is not suitable to use desktop CO2 in closed areas with consistently high CO2 levels 24 hours a day Manual Calibration Manual calibration is suggested to be done outdoors on a sunny day with good ventilation and fresh air where the CO2 level is approximately 400 ppm Do not calibrate on a rainy day because high humidity will affect the CO2 level in air Do not calibrate in places crowded with people or close to where high CO2 concentrations may exist such as ventilating outlets or fireplaces Place the meter in the calibration site Turn on the meter and hold down the SET A and MIN MAX Y buttons simultaneously more than 1 second to enter CO2 calibration mode 400ppm and CO2 will blink while the calibration is in process The calibration will take about 30 minutes When the calibration is complete the blinking stops and the meter returns to normal operation To abort
