Operating the fan anemometer
46

When starting the measurement mode , direct
the fan anemometer slowly and steady over
the entire area of the air passage.
HINWEIS!
Make sure to stop the measurement by pressing
the button immediately after the data record has
been finished, because the calculation of the av-
erage will not be correct, if the average measure-
ment mode is stopped after the device has been
removed from the air passage.
