4. Technical Specifications

4.1 Main Performance

A. SpO2 value display
B. Pulse rate value display, bar graph display
C. Pulse waveform display
D. Low-voltage indication: low-voltage indicator appears before
working abnormally which is due to low-voltage
E. Display direction can be changed automatically, easy to view.
F. The product will enter standby mode when no signal is in the
product within 5 seconds.
G. A pulse rate sound indication
H. With alarm function
I. With SpO2 value and pulse rate value of storage,the stored data
can be uploaded to computers
J. Data can be transmitted to computers

4.2 Main Parameters

A. Measurement of SpO2
Measuring range: 0%~100％
Accuracy: 70% ~ 100%, ±2%; 0% ~ 69%, 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
