SpO2 Measuring Range: 0%~100%, (the resolution is 1%).
Accuracy: 70%~100%: ±2% ,Below 70% unspecified.
PR Measuring Range: 30bpm~250bpm, (the resolution is 1bpm)
Accuracy: ±2bpm or ±2% (select larger)
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%
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%.
