Measurement of pulse rate
Measuring range: 30bpm

250bpm
Accuracy: ±2 bpm or ±2% (whichever is greater) .
Resolution
SpO2 : 1%, Pulse rate: 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%, pulse rate error is ±2 bpm or ±2% (whichever is greater).
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%.
Power supply requirement:
DC 3.0V.
Optical Sensor
Red light (wavelength is 660nm, 6.65mW)
Infrared (wavelength is 880nm, 6.75mW)
Adjustable alarm range:
SpO2: 0% ~ 100%
Pulse Rate: 0bpm ~ 254bpm
