Measurement Performance in Weak Filling Condition : Oxyhemoglobin and pulse ＆ #118alue can be shown correctly when pulse-filling ratio is 0.4%.
Interference Resistance Capacity against Ambient Light : Deviation is smaller than 11%between ＆ #118alue of Oxyhemoglobin measured in natural lighting indoor condition and present
lighting sources and that measured in dark room.
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.
