Technical Parameters
· Measurement of Sp02
· Measuring range: 0-100
· Accuracy: When the Sp02 measure range is 70%-100%,
the permission of absolute error is ±2%
· Below 70% unspecified
· Measurement of pulse rate
· Measure range: 30bpm-250bpm
· Accuracy: ±2 bpm or ±2%(select larger)
· Measurement of PI
· Measure range: 0-20%
· When the PI measure range is 1%-20% the permission of absolute error is ±0.2%
· When the PI measure range is 0%-0.9%, the permission of absolute error is ±0.2%
· Resolution: Sp02: 1% Pulse rate: lbpm PI: 0.1%
· Measurement performance in weak filling condition
· Sp02 and pulse rate value can be shown correctly when pulse-filling ratio is 0.4%.
· Sp02 error is ±4%; pulse rate error is ±2bpm or ±2%(select larger) Resistance to surrounding light
· The deviation between the value measured in the condition of man-made light or indoor
natural light that of darkroom is less than ±1%
· Operating Voltage: Internal power supply: 3.6 V DC-4.2V DC
· Exterior alternating current supply: 100-240VAC 50/60 Hz
