| Measurement of SpO2 | Measure range: 0% to 100%
Accuracy: When SpO2 measure range is 70% to 100%, the permission of absolute error is ± 2%. Below 70% unspecified. |
| Measurement of Pulse Rate | Measure range: 30 bpm to 250 bpm
Accuracy: ± 2 bpm or ± 2% (select larger). |
| Measurement of PI (Perfusion Index) | Measure range: 0% to 20%
When PI measure range is 1% to 20%, the permission of absolute error is ± 1%. When PI measure range is 0% to 0.9%, the permission of absolute error is ± 0.2%. |
| Resolution | SpO2: 1%, Pulse rate: 1 bpm, PI: 0.1%. |
| Measurement Performance in Weak Filling Condition | SpO2 and pulse rate value can be shown correctly when pulse-filling ratio is 0.4%. SpO2 error is ± 4%, pulse rate error is ± 2 bpm or ± 2% (select larger). |
| Resistance to Surrounding Light | The deviation between the value measured in the condition of man-made light or indoor natural light and that of a darkroom is less than ± 1%. |
| Operating Voltage | Internal power supply: 3.6 V DC to 4.2 V DC
