Performance
- SpO2 measurement range: 0%~100%
- Accuracy:
- 70%~100%: ±2%

- PR measurement range: 30bpm~250bpm
- Accuracy: ±2bpm or ±2%, whichever is greater.
- Resolution:
- SpO2: 1%
- PR: 1bpm
Measuring performance in low charge condition: SpO2 and heart rate can be correctly displayed when the pulse-to-charge ratio is 0.4%. SpO2 error is ±4%, heart rate error is ±2bpm or ±2%, whichever is larger.
Resistance to ambient light: The deviation between the value measured in artificial or indoor natural light and the value measured in the darkroom is less than ±1%.
