Data is not accurate Analysis 1. Particulate matter data has a certain spatial and temporal nature, sampling do not in the air flow velocity fluctuations or particulate matter changes obviously, if necessary, you can sample data multiple times 2. No data display of the number of particles in the air and concentration quality Problems Manual mode when not pressed sampling Battery power is too low to start the sensor work Temperature and humidity are not accurate Analysis 1. Temperature and humidity sensor sampling window with debris, dirty Problems 1. Ventilation window is blocked by something 2. Do not turn on Analysis 1. The battery is dead or damaged, powered by USB socket, if you can turn on and the upper right corner of the power grid has changed, is the battery is dead, such as no change only shows OK icon. Indicates that the battery has been damaged. 2. The battery +/- polarity is reversed, it should be noted that one end of the battery without a protruding contact point is the "-" pole, and the end with a protruding contact point is the "+" pole.
