Hand held Anemometer 

Operating Manual 

Introduction: 

Congratulations on purchasing this pocket-sized anemometer. This 

innovative product provides wind speed, wind chill and temperature 

information for any outdoor activity. The operation of this product is 

simple and straightforward and by reading this operating manual, 

users will receive the optimum benefits of all its features. 

The Anemometer 

Features: 

• Wind speed measure in mph, Km/h, m/s or Knots 

• Wind speed in Beaufort wind scale bar graph 

• Wind chill display 

• Temperature display in degrees Fahrenheit or Celsius 

• LCD backlight 

• Auto power OFF 

• Neck band included 

• Weather resistant casing 

Setting up:

1. First use a large coin to open 

the battery cover at the back 

of the anemometer as 

indicated above. 

2. Checking the correct 

polarization, insert 

1 x 3V (CR2032) lithium cell, 

positive (+) pole up into the 

battery compartment and 

replace the cover. 

3. When the battery is inserted, 

all the segments of the LCD 

and backlight will light up 

briefly. 

Your anemometer is now operational.

Note: 

After inserting the battery, test the anemometer by blowing directly at 

the Impeller for about 30 seconds. The reading on the LCD should 

change. If this does not happen remove the battery, wait for 30 

seconds, and re-insert the battery. 

Function keys: 

The anemometer uses the following keys: 

MODE/~ key: To toggle between wind speed and temperature/wind 

chill display 

: Power ON/OFF 

: To enter the setting mode 

: To turn the backlight On 

+ Key : To change operation mode 

: To change parameters in setting mode 

: To turn the backlight On

Selection of operation mode 

There are two modes, one is wind speed, and the other is 

temperature. By pressing the “MODE/~” key the display will toggle 

between the two modes. 

Wind Speed Mode 

The wind speed mode can be selected to 3 different display modes at 

any time.

 

To toggle between current wind speed, maximum wind speed and 

average wind speed, simply press the “+” key: 

Beaufort wind scale (bft)

The Beaufort scale is displayed in bar graph (0-12). This is a system 

for estimating wind force without the use of instruments based on the 

visible effects of the wind on the physical environment. 

Temperature/ Wind Chill Mode 

The temperature/ wind chill modes can be selected to 2 different 

display modes at any time.

Temperature Wind chill

By pressing the “+” key the display will toggle between temperature 

and wind chill. 

Note: 

When the temperature is outside the range from –29°C to +59°C, 

there will be no wind chill measurement. 

Wind chill 

The anemometer calculates automatically wind chill, which can 

provide useful information for preparing outdoor activities in cold 

weather. “Wind chill” provides an indication of how cold it feels given 

the combined effects of the actual air temperature and the wind 

speed. 

Power ON/OFF: 

Press and hold down the “MODE/~” key for 4 seconds to switch the 

unit ON or OFF. 

Note: 

The anemometer is automatically switched OFF when no key is 

pressed in 34 minutes.

Manual setting 

Note: 

Before entering the manual setting mode switch off the anemometer. 

Press and hold down the “MODE/~” key for about 6 seconds, the 

speed unit will start flashing on the right side of the LCD when the 

manual setting mode is entered.

Measurement scale setting 

1. After entering the manual setting mode, press “+” key to set the 

measurement scale in Km/h (Kilometers per hour), mph (miles 

per hour), m/s (meters per seconds) or Kts (Knots). 

2. Now press the “MODE/~” key to confirm and enter the “°C and 

°F setting”. 

°C and °F setting:

1. Following from the measurement scale Setting °C will be 

flashing, use the “+” key to toggle °C and °F. 

2. Once the desired temperature unit has been chosen, press the 

“MODE/~” key to confirm and enter the “Average time for 

current speed measurement setting”. 

Average time for current speed measurement setting 

The current wind speed can be measured in average wind speed in a 

time interval of 2-10 seconds 

1. Following from the °C and °F Setting, press “+” key to set the 

desired average time. The range runs from 2 to 10 seconds. 

2. Once the desired average time has been chosen, press the 

“MODE/~” key to confirm and back to the normal mode.
