Measuring Wind Speed
The Windwatch PRO is designed to precisely measure the wind
speed regardless of the prevailing air density. In order to obtain
optimal results, the instrument should be held vertically into the
wind with an outstretched arm. To insure the greatest accuracy,
measurements should be taken where there are minimal
obstructions upwind of your position that might cause turbulence.

The internal impeller in the WWP is precisely balanced and suspended
on two sapphire bearings and is sensitive to dust, dirt and impact. To
protect the impeller and the temperature and humidity sensors, the
WWP is equipped with a convenient protective slider that should be
closed whenever measurements are not being taken. Using the
protective slider will insure many years of reliable service from the
internal sensors.

wind chill temperature value, the middle line shows the average
wind speed, and the bottom line shows the ambient
temperature without the wind chill factor. The measuring units
for the wind speed can be scrolled with the▼ or ▲ key.
