SpO2 measurement range: 0%~100%
Accuracy: 70%~100%: + / - 2%
0%~69%: unspecified
PR measurement range: 30bpm~250bpm
Accuracy: + / - 2bpm or + / - 2%, whichever is greater.

SpO2: 1%
PR: 1bpm

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% at this level of perfusion. the pulse rate error is 2 bpm or 2%, whichever is greater.

The unit also has 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%.
