I.
Performance under low perfusion condition
The accuracy of SpO
2
and PR measurement still
meets the specification described above when the
modulation amplitude is as low as 0.6%.
J.
Resistance to interference of surrounding light:
The difference between the SpO
2
value measured in
the condition of indoor natural light and that of
darkroom is less than ±1%.
K.
Resistance to 50Hz /60Hz interference:
SpO
2
and PR are precise which have been tested by
BIO-TEK pulse oximeter simulator.
