7 Principles of Operation
H100N Pulse Oximeter adopts non-invasive double
wavelength to measure SpO
2
and PR. It can perform spot
measuring and continuous measuring for a short time. It
can also measure TEMP by a thermistor probe (a
semiconductor whose resistance changes with
temperature).
The system consists of Central Processing Unit, Signal
Collection, Signal Input, Data Output, Display and User
Input module, as shown in figure 7-1:
