Mini Airflow goes off automatically 1 minute after the button was last pressed or after the wind was last measured. This means
that it does not stop while the impeller is still turning (more than 10 seconds).
Switching off manually :
In order to switch Mini Airflow off manually (valid in every mode), hold the button pressed down until it switches off, then release.
IMPORTANT ! Permanent operation possible :
Either at the time of the manual switching off by releasing the button during the flashing of the large digits, or at the time of automatic switching
off by pressing briefly on the button during the flashing.
During permanent operation, any pressure on the button returns Mini Airflow into automatic off mode.
Note : if the instrument is on permanently the battery discharges rapidly (400 to 500 hours according to the model).
