Resolution: A?1% for SPO2 and A?1 BPM for Pulse Ratio.
Measurement Accuracy: A?2% in stage of 70%-99% SPO2 and meaningless when stage

being smaller than 70%. A?2BPM for Pulse Ratio.

Measurement Performance in Weak Filling Condition : Oxyhemoglobin and pulse i??#118alue can

be shown correctly when pulse-filling ratio is 0.4%.
Interference Resistance Capacity against Ambient Light : Deviation is smaller than A?1%

between i??#118alue of Oxyhemoglobin measured in natural lighting indoor condition and present

lighting sources and that measured in dark room.

a?? It is equipped with a function switch, hrough which the Oximeter can be automatically powered

off when no finger is in the Oximeter more than 8 seconds.
