The measuring device is capable of measuring wind speed or air
× ow with the built-in fan wheel. The resulting measurements can
be output in various units. On the basis of these quantities, it is also
possible to measure volumetric
× ow.
After switching on the device, press the „Anemo“ button. Press the
„Unit“ button repeatedly to change the units: FPM (feet per minute),
knots, m/s (metres per second) and km/h (kilometres per hour). Press
the „Anemo“ button again if you want to determine the volumetric
× ow. Use the „Unit“ button to switch between the units CMM (cubic
metres per minute) and CFM (cubic feet per minute). Firstly, measure
the
× ow opening area. Then you can set the measured area by pres-
sing the „Set“ button and making the necessary adjustments with the
„Unit“ (change position of decimal point), „Hold“ (+) and „Illuminati-
on“ (-) buttons. Press the „Set“ button to con
Ö rm your entry.
Please observe the following application notices when deter-
mining wind speed/air
ƃ ow:
– Avoid direct sunlight during the measurement process
– Place the device as close as possible to the source of the air
× ow
– Position the device parallel to the source of the air × ow
– Use the MAX function to determine the point where the air × ow
is greatest
By pressing the „Mode“ button, you can get the device to display
the highest (MAX), lowest (MIN), average (AVG) or difference value
(DIF) in addition to the current measured value. As its name sug-
gests, the „HOLD“ button enables you to hold the current measured
value.
