PRINCIPLE
Firstly, testee deep inspires, then seals the lips around the mouthpiece and blasts all air out as forcefully as possi-
ble, 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 ac-
quisition 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.
