1. When measuring, keep the air relatively still and not flowing, and the measuring person should stay away from one arm or so;
2. When the battery power is low, it needs to be fully charged. Under normal circumstances, the battery usage time is about 5-6 hours, otherwise the measurement results will produce a large error in low power.
3. The data value should take the middle reading of the numerical range that appears.
