turn it back on and press the “Mode” button for about 3 seconds
until the “m/s” starts to blink. Press the “Set” button to navigate
through the units of wind speed and into the choices of
wind speed measurement – “Cu” for current wind speed,
“MAX” for maximum wind speed and “AVG” for average wind
speed. Press the “Mode” button to confirm your choice.
The setting will be stored in your unit even after turning it off.
The MAX wind speed will indicate the highest wind speed
recorded once it is set unless you reset to another measurement
unit. The AVG wind speed will indicate the last 8 sample periods
or 4 seconds of running average.
w
Wind Display on the LCD – When the impeller (fan/vane)
turns, the LCD will instantly display the wind speed and
temperature per the settings you chose along with the
Beaufort scale.
