Product Usage Instructions
Functionality
The Anemometer has the following functions:
- Wind speed measurement
- Barometer indicator
- Temperature/humidity/dew point/wind chill indication
- Altitude measurement
- Measure wind speed in: Current/Max/Min/Average
- Low battery warning
- LCD back-light
- Auto / Manual power off (Note: It will not auto power off in the interface of barometer indication)
Operation
- Open the battery compartment and insert the battery.
- Screw down the battery cover and press the power button for 1 second to turn on the unit. The LCD will display wind speed, temperature, and battery icon.
- To power off, press the power button again.
- Press the selection button (
<button>) to select different wind speed units.

Function
- Wind speed measurement
- Barometer indicator
- Temperature/humidity/dew point/wind chill indication
- Altitude measurement
- Measure wind speed in: Current/Max/Min/Average
- Low battery warning
- LCD back-light
- Auto / Manual power off (Note: It will not auto power off in the interface of barometer indication)
Operation
- Put battery into battery compartment.
- Recover battery cover, screw down press“①”in 1 second to turn on the unit. LCD will display wind speed, temperature and battery icon. Press again, it will power off.
- Press “ ② ” to select different wind speed unit:
- Press “②”each time, it will circulated among “m/s”, “Km/h ”, “Ft/min”, “Knots”,and “MPH” .
- Digit symbol:
- m/s: meter per second; Km/h: kilometer per hour;
- Ft/min: feet per minute; Knots: nautical mile per hour;
- MPH: mile per hour.
- Press “ ③ ” to select different barometric pressure unit: Press “ ③ ”each time, it will circulated between “inHg” and “hpa mbar”. Press and hold“③” for above 3 seconds, it will enter to the reading of barometric pressure mode. There are total 16 groups data, and record the barometric pressure 1 times per hour. Now you press it, you can check the 16 groups data. Press and hold “ ③ ” again, it will exit to the reading of barometric pressure mode.
- Digit symbol:
- inHg: inches of mercury
- hpa mbar: millibars / hectopascals.
- 1(inHg) =33.8638816(hpa)
- Press“④ ” to select altitude unit, press”④ ” each time, it will circulated between “M” and “FT”.
- Note: As the altitude is the conversion from atmospheric pressure, in different periods, the uneven air density which is caused by climate will lead to different altitude.
- Digit symbol:
- M: meter; FT: feet.
- 1(m)=3.2808399(ft)
- Press and hold ”④ ”, it will go in to the mode of the barometric pressure calibration. You can calibrate according to the barometric pressure in your local. Press “②” to go up in units, press“⑤” to go down in units. After the adjustment is completed, press and hold”④” again, the data will be saved and it will exit to the calibration mode.
- Press”⑤” each time, it will circulated among “℃”, “℉”, “RH%”, “DP-℃”, “DP-℉”, “WCL-℃” and “WCL-℉”.
- Digit symbol:
- ℃: Centigrade; ℉: Fahrenheit; RH%: Relative Humidity;
- DP-℃: Dew point centigrade;
- DP-℉: Dew point degree fahrenheit;
- WCL-℃: wind chill centigrade;
- WCL-℉: wind chill fahrenheit.
- WCL: The wind chill index is a physical quantity that characterizes the relationship between the wind speed and the cooling.
- DP: Displays the temperature at which air becomes saturated with moisture (the temperature at which fog will form)
- Press “⑥” each time to select “MAX”, “AVG”, “MIN” of wind speed. Press and hold“ ⑥ ” for above 3 seconds, back light will turn on. Press and hold “ ⑥ ” for above 3 seconds again, it will turn off.
