Chapter 3 Principle
Firstly, testee deep inspires, then seals the lips around the mouthpiece
and blasts all air out as forcefully as possible, the exhalant gas transforms
to rotary airflow by turbine, then makes the blade rotate. The reception
part of the infrared pair diodes (one is for infrared emission, the other is
reception) towards to the blade is used for receiving the infrared ray, when
the blade rotates, the received ray strength of the reception diode will be
different as the difference of the blade angle, so form the various signal
of same proportion in reception diode, which forms acquisition signal by
SCM after processing. At last, various parameters to be measured formed
from the information which were processed by the microprocessor, and
displayed from the screen.

4.1 MAIN PERFORMANCE
‹ Forced Vital Capacity (FVC), Forced Expired Volume in one second
(FEV1), the ratio of FEV1 and FVC (FEV1%), Peak expiratory flow (PEF),
25% flow of the FVC (FEF25), 75% flow of the FVC (FEF75) and average
flow between 25% and 75% of the FVC (FEF2575) can be measured.
Besides, the testee condition can be shown by the ratio of the measu-
red value and the predicted value.
‹ Flow rate-volume chart, volume-time chart display.
‹ Data memory, delete, upload and review.
