mode, please refer to the Chapter 6.2.
NOTE!
For the measurement of the volume flow at air
passages without funnel we recommend the
measurement mode "Average value determined
over time".(chapter 5.8.1)
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.
