Extended Specifications Measurement of SpO2 Measuring range: 0%～99% Accuracy: When the SpO2 measuring range is 70%～99%, the permission of absolute error is ±2%; Below 70% unspecified Measuring range:30bpm～250bpm Accuracy: ±2 bpm or ±2% (select larger) Power supply requirement 3.6 V DC ~ 4.2V DC Rechargeable Battery Resolution SpO2 : 1%, Pulse rate: 1bpm Measurement Performance in Weak Filling Condition: SpO2 and pulse rate can be shown correctly when the pulse-filling ratio is 0.4%. SpO2 error is ±4%, pulse rate error is ±2 bpm or ±2%. Resistance to surrounding light. The deviation between the value measured in the condition of man-made light or indoor natural light and that of the darkroom is less than ±1%.
