L. With clock function
4.2 Main Parameters
A. Measurement of SpO2
Measuring range: 0%~100％
Accuracy: When the SpO2 measuring range is 70%~100%, the
permission of absolute error is ±2%, Below 70% unspecified.
B. Measurement of pulse rate
Measuring range: 30bpm~250bpm
Accuracy: ±2 bpm or ±2% (select larger)
C. Resolution
SpO2: 1%, Pulse rate: 1bpm
D. 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%
(select larger).
E. 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%.
F. Power supply requirement
2.6 V DC ~3.6V DC.
G. Optical Sensor
Red light (wavelength is 660nm, 6.65mW)
Infrared (wavelength is 880nm, 6.75mW)
H. Adjustable alarm range
SpO2: 0%~100%
Pulse Rate: 0bpm~254bpm
