How WindMaster Measures Wind Speed - WindMaster features a propeller that is similar to an aerovane. When the propellers facing the wind, it rotates at a rate that is direct proportional to the wind speed. Before Measuring a Wind Speed - Press the both Propeller Release Buttons together to release the propeller unit. - Turn the ball-shape propeller by your thumb and index fingers until the propeller blades are entirely opened to air current and is not sheltered by the case. To Measure Wind Speed - Select Wind Speed Mode. - Point the propeller's tunnel direct towards the wind direction. - Make sure that the propeller blades are free to rotate. - Whenever the wind pass through the propeller, the blades rotate. - The WindMaster starts to measure and shows the average wind speed or wind chill factor, maximum and current wind speed. After Measuring a Wind Speed - Important: After a wind speed measurement, close the propeller to prevent dirt gets into it. - Push the propeller unit back to its normal position until a 'click' sound. Wind Speed Mode - Wind Speed Mode has two sub-displays: Wind Chill Factor Display and Average Wind Speed Display. - Press [start/stop] button to switch between the Wind Chill Factor Display and Average Wind Speed Display. Average Wind Speed Display - When the average wind speed display is being selected, the average wind speed will be displayed on the top left corner of the display. The maximum wind speed displays on the top right corner of the display. The current wind speed displays on the bottom row of the display. - The bar indicators on the both sides of the display indicate the current wind speed in Beaufort Scale. Wind Chill Display - When Wind Chill Display is being selected, the wind chill factor will be displayed on the top left corner of the display. The maximum wind speed displays on the top right corner of the display. The current wind speed displays on the bottom row of the display. - The bar indicators on the both sides of the display indicate the current wind speed in Beaufort Scale. IMPORTANT: If the user intends to get an accurate reading of air temperature as well as wind chill factor, the user must taken off the watch from the wrist for 20 to 30 minutes before the actual measurement. It allows no body temperature effect on the watch. To Reset the Maximum Wind Speed - Press and hold the [Adjust] button for 2 seconds to reset the maximum wind speed, when the maximum wind speed is displaying. What is Wind Chill Factor - The wind chill factor is a temperature factor that combine the temperature and wind blowing effects. As blowing wind makes you feel as though the temperature is bottom than the actual one. - For instant, if it is 10 degree Celsius and the wind blows at 10 miles an hour, people feel as if the temperature is minus 9 degree Celsius at no wind condition. In this case, the wind chill factor is minus 9 degree Celsius. What is Beaufort Scale - Beaufort Scale is the longest and most widely used set of criteria to describe the wind. - Beaufort Scale is a standard that describes wind conditions and its effects on land as well as at sea. Beaufort Scale standardize the wind speed into 13 categories, from 0 (calm) to 12 (hurricane). - Check the 'Beaufort Scale' table for detail. To Switch among Units - The WindMaster displays wind speed in Km/h (Kilometer per hour), mph (mile per hour), Knots, m/s (meter per second) and fps (feet per second) unit. - Press and hold [start/stop] button to change the unit as in the unit selection sequence. Release the button as desire unit was displayed. Wind Speed Mode Auto Return - In Wind Speed Mode, if there is no key operation for 30 minutes and the current wind speed is zero, the WindMaster will return to Real Time Mode. Use the Propeller as a Mechanical Compass - Your WINDMASTER measures temperature, pressure, altitude, wind speed, the WindMaster tells compass directions as well. - One of the propeller blades was colored to indicate the north pole. - Eight bearing marks ( North, North-East, East, SouthEast, South, South-West, West, and North-west) were engraved on the propeller unit as reference points. To use the Mechanical Compass - To check bearing, make sure the propeller is opened and the propeller unit in it's normal position. - Tilt your WindMaster until the propeller blades are parallel to horizon. The propeller blades should be free to rotate. - Minimize the air current pass though the propeller tunnel when you taking a compass reading. - The greenish-yellow coloured blade of the propeller indicates the direction of north pole. - Make use of the bearing marks on the propeller unit to check out other directions.
