performance
1) Display Mode:LCD display
2) SpO2 Measuring Range:0%~100%, (the resolution is 1%).
Accuracy:70%~100%:±2% ,Below 70% unspecified.
3) PR Measuring Range:30 bpm~250 bpm, (the resolution is 1 bpm)
Accuracy:±2 bpm or ±2% (select larger)
4) PI Measuring Range: 0 %~ 20%
Accuracy:When the PI measure range is 1%~20%,the permission of absolute error is ±1%
When the PI measure range is 0%~0.9%,the permission of absolute error is ±0.2%
