5.1. Measuring Procedure

1. Press the ON/OFF button to turn the
monitor on. The last result will
appear on the display (0 if there is
no data). The device will sound two
short beeps and arrows will blink to
indicate it is ready for
measurement.

while standing or sitting upright.
For better comparison of your data,
you should always perform the
measurement in a similar position.
3. Hold the monitor with both hands
on the two textured compartments.
4. Inhale completely and hold your
breath for a moment.
5. Cover the mouthpiece tightly with
your lips.
6. Blow into the measuring tube as
hard and as fast as you can.

is recorded. PEF is displayed for
about 3 seconds followed by FEV1.
Then, the monitor will sound two
short beeps indicating that it is
ready for a new measurement.
