C-LOGIC 280 • Digital anemometer
4.4 Wind speed measurement
Place the detector (fan) into the test environment, "VEL" symbol will display on
the screen, measurement is done with the fan surface perpendicularly to the
wind direction.
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 get maximum reading when it is aiming
at the wind direction.
4.5 Speed unit 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).
4.6 Area setting
To measure air volume, you should first determine the area of air flue to be,
area input steps are shown as following:
1) Press "FUN" 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.
4.7 Air volume measurement
Place the detector (fan) into the test environment. Use the "FUN" 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.
4.8 Air volume unit selection
When using the meter to measure air volume, you can press the "UNIT" key to
select the measurement unit your required (CMS, CMM, CFM).
