Best practice is to download the Aranet app, sync it to the CO2 monitor, and watch the CO2 levels on your smartphone in real time.

CO2 monitors allow you to measure, in real time, the ventilation and air quality in a room. When lots of fresh air is being circulated in a venue, the CO2 reading will be close to what you would expect outdoors (400 ppm).
But when ventilation isn’t great and lots of people inside are breathing, the CO2 levels rise (because we release CO2 in our breath). Anything above 1,000 ppm requires action! Open windows and doors, turn up the HVAC, and turn up the purifier(s) in the space, etc.
