measurement technology is based on developed photoelectron
method, the circuit design and calculation software was
developed by Shenzhen Viatom Technology Co., Ltd. The
SpO
2
sensor receives the optical signal from the red light and
infra-red light through the finger. Insert the finger into the
oximeter, there are two emitting tube (red light diodes and
infrared diodes) located on the inner upside of the sensor and
they can emit red light and infrared; There is the receiving
end located on the inner downside of the sensor, and it can
transmit the red light and infrared into the pulse signal
through finger. The MCU receives the pulse signal, gets the
frequency signal by counting, processes its digital signal, and
finally gets the measured SpO
2
value. The PR is averagely
calculated by above peak intervals of PR waveform.

Stop working & sync data
Unplug the sensor cable, the countdown
on the screen will begin.
During the countdown, if you plug the sensor cable again, the
record will be resumed.
After the countdown
, the
data will be ready for sync
.
Notice:
If the working time is less than 2 minute, there will be
no data saved
If the device power off during working, the data should
have been saved.
Sync data
:
After the countdown, run App to sync data; If App has
already opened, go to History page to sync data.
You can also sync data later.
The built-in memory can
