4.2  How to Perform Measurements with the AM3
To perform a valid PEF measurement with the AM3, the following steps must be 
followed:
1.  Inhale deeply and hold your breath until you have positioned the inlet of the 
flow sensor into your mouth.
You should
•  pause for about a second and then blow out hard and fast as you can.
•  not cough. 
•  not block the inlet of the flow sensor with your tongue. 
•  not block the outlet of the flow sensor with your hand.
If you do not follow these instructions, the correctness of the measure-
ment values cannot be guaranteed.
2.  Now you must exhale as hard as possible for at least 2 seconds to obtain a 
satisfactory measurement.
