Frequently Asked Questions
1. What type of display does this pulse oximeter feature?
A: This pulse oximeter features a 0.96″ Dual-color OLED display (blue and yellow) with a 128*64 screen resolution. It displays SpO2 value, pulse rate value, bar graph, and pulse waveform for convenient monitoring.
2. What are the SpO2 and pulse rate measuring ranges of this device?
A: The device offers an SpO2 Measuring Range of 0%-100%, with a resolution of 1%, and a PR Measuring Range of 30bpm,250bpm, with a resolution of 1bpm.
3. What is the measurement accuracy of this pulse oximeter?
A: The SpO2 accuracy is ±2% within the specified 70,100% range, while accuracy below 70% is unspecified. The pulse rate accuracy is ±2bpm or ±2%, whichever is larger.
4. Can this pulse oximeter measure SpO2 and pulse rate under weak filling conditions?
A: Yes, SpO2 and pulse rate can be shown correctly when the pulse-filling ratio is 0.4%. Under this condition, the SpO2 error is ±4%, and the pulse rate error is ±2bpm or ±2%, whichever is larger.
5. What is the battery life and power consumption of this pulse oximeter?
A: The device operates using 2 × 1.5V (AAA size) alkaline batteries, with a theoretical battery working hour of 32 hours. Its power consumption is less than 30mA, and the specified operating voltage is DC 2.6V~3.6V.
6. What additional features does this pulse oximeter offer?
A: The device features adjustable display mode and screen brightness, pulse waveform display, pulse rate value display, bar graph display, and a low-voltage indication that appears before low voltage causes abnormal operation. Its resistance to surrounding light ensures that the deviation between readings under man-made light or indoor natural light and darkroom conditions is less than ±1%.
