Using tips:
n This device’s accuracy will be influenced by itself body, installation environment’s temperature, humidity and other factors. So the best installation environment is:
n temperature: 20°C±5°C;
n humidity: 50%, don’t put in the air of the humidity is over 80%
n far away from the places where it has phone and other electromagnetic interference;
n Keep it away from the corrosive or harmful substances;
n Don’t put it in high co concentration environment in order to save its lifetime.
