FIRST USE
This device has an ABC CO2 sensor (Automatic Baseline Calibration). This means that the equipment will need 24 hours after the first start-up to obtain a base value and be able to give appropriate measurements. After this first calibration, the equipment stores it in its internal memory and verifies that the value is correct on a daily basis.
The first time you use the equipment, leave it charging in a well-ventilated environment for 24 hours. When charging, the battery icon light will alternate between green-orange-red. When it is 100%, it will stay green.
