Note:
‧If the detector (fan) is not aiming at the wind direction, which
will bring the measurement error.
‧For steady wind, the detector (fan) will register maximum
reading when it is aiming at the wind direction.
Wind speed measurement
When using the meter to measure air volume, you can press
“UNIT” key to select the measurement unit you required (m/s,
km/h, mill/h, ft/m, ft/s, knots).
Area setting
To measure air volume, you should first determine the area of
air flow to be, input steps are shown as following:
①.Press “FUNC” key to make “AREA” display on the screen.
②.Use the “MAX/MIN” and “UNIT” keys to adjust value and
unit, after adjusting area unit (m², ft²), then press
“MAX/MIN” key. There should be an audible buzz,
indicating that area input is completed and settings are
saved.
③.To change the area setting, please repeat the step ②.
Air volume measurement
Place the detector (fan) into the test environment. Use the
“FUNC” key to set the meter to the Air volume measurement
mode; the "FLOW" symbol should display on the screen.
Measurement is done with the fan surface perpendicular to the
wind direction.
Note:
‧If the detector (fan) is not aligned in the wind direction, the
measurement can be skewed.
‧For steady wind, the detector (fan) will get maximum reading
when it is aiming at the wind direction.
