3. Power Consumption: Smaller than 30mA.
4. Resolution: 1% for SpO
2 and 1 bpm for Pulse Rate.
5. Measurement Accuracy: ±2% in stage of 70%-
100% SpO
2, and meaningless when stage being
smaller than 70%. ±2 bpm or±2% (select larger)
for Pulse Rate.
6. Measurement Performance in Weak Filling Condi-
tion: SpO
2 and pulse rate can be shown correctly
when pulse-lling ratio is 0.4%. SpO
2 error is
±4%, pulse rate error is ±2 bpm or ±2% (select
larger).
7. 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%.
8. It is equipped with a function switch. The Oxime-
ter can be powered off in case no nger is in the
Oximeter within 5 seconds.
9. Optical Sensor
