3.Performance
1)Measurement range of SpO2: 0%~100%, error: 70%~100%: ±2%; 0%~69%: unspecified;
2)Measurement range of pulse rate: 30bpm~250bpm, error: ±2bpm or ±2%(select the larger);
3)Measurement range of heart rate: 30bpm~300bpm, display error is ±1bpm or 1%(select the larger);
4)Resolution：SpO2 : 1%, Pulse rate: 1bpm;
5)Measurement Performance in Weak Filling Condition:SpO2 and pulse rate can be shown correctly when pulse-filling ratio is 0.4%. SpO2 error is ±4%, pulse rate error is ±2 bpm or ±2% (select larger);
6)Resistance to surrounding light: The deviation between the value measured in the condition of man-made light or indoor natural light and that of darkroom is less than ±1%;
7)Pedometer range: 0~65535steps (resolution: one step);
8)Operating Current: ≤100mA;
