To power on and measure with the KDF-CO2-AQ1 Mini 3 in 1 NDIR CO2 Desktop Monitor, you need to connect the USB cable to a PC or a USB wall adapter. After powering on, the bars on the LCD will decrease during warm-up. Once the warm-up is complete, the device will start measuring the CO2 concentration, ambient temperature, and relative humidity. The measurements will be displayed on the LCD screen.
