MODE: INSTANT WIND SPEED WITH MAXIMUM

Choice of wind speed measurement unit:To select the wind speed measurement units, the Xplorer must be in the instant wind speed and maximum wind speed mode. By keeping the button pressed for approximately 4 seconds, the units start to change . You can choose between the following units : km/h (kilometers per hour), mph (miles per hour), knots, m/s (metres per second), and fps (feet per second) . When the unit of your choice appears, release the button and the unit of measurement is thereby selected . This unit will remain on all wind measurements until changed, even after the Xplorer is turned off .

Measurement of speed: For the measurement to be as exact as possible it is necessary to align the instrument along the axis of the wind .

Display:The display of the current speed is done on the large digits and the maximum speed reached on the small digits with the indication max .

Deletion of the maximum:The maximum is retained even when the instrument is off . In order to reset it to zero keep the button pressed for at least 2 seconds, then release it .

Accuracy: +/-3% from 1 .1 mph to 93 mphMeasuring range: from 1 .0 to over 93 mph (42 m/s, 81 knots, 150 km/h, 136 fps)Measuring cycle: 2 measurements per secondResolution: to one decimal place up to 99 .9, then in whole unitsDisplay range: from 0 .0 to 299 units (accuracy is reduced when over the stated range)

10

MODE: INSTANT WIND SPEED WITH AMBIENT TEMPERATURE

Choice of temperature measurement unit:To select the temperature measurement units, the Xplorer must be in the instant wind speed and temperature OR wind chill. By keeping the button pressed down for at least 2 seconds the units start to change . The units possible are °C (degrees Celsius) and °F (degrees Fahrenheit) When the unit of your choice appears, release the button and the unit of measurement is thereby selected .

Measuring ambient temperature: Note: the temperature sensor is integrated with the metal back of the casing, and therefore it is the temperature of the back of the casing which is displayed . This

special feature makes it possible to measure very accurately the temperatures such as: water (springs, streams, etc .) by immersing the instrument several centimeters; •surfaces (ground, metal parts, refrigerator interiors etc) by laying as closely as possible the back •of the instrument on the surface to be measured; ambient air, either by allowing the instrument to reach the air temperature, which can take •several minutes, or even several dozens of minutes according to the wind speed (avoid direct sunraysandcontactofthebackofthecasingwithyourfingers).Otherwise,togetarapidandprecise measurement, but the back of the casing into contact with an object which is the same temperature as the air (vehicle bodywork, metal barrier, smooth walls etc .) avoiding surfaces in dark colors and exposed to sunlight) .

Display:The display of the instant wind speed is done on the large digits while the ambient temperature is displayed on the small digits .

Measuring cycle: 2 measurements per second with 0 .1°F/C resolutionMeasuring range: -58°F to 212°F (-50°C to 100°C)Accuracy: +/- 0 .5°F (0 .3°C)

11

MODE: CURRENT WIND SPEED WITH WIND CHILL TEMPERATURE

Choice of temperature measurement unit:See previous section, Wind Speed with Ambient Temperature .

Wind Chill Information:Low temperatures present a danger to the human body and this danger is aggravated by the speed of the wind . The Xplorer 2 shows immediately the temperature felt by the body and warns of risks of frostbite and hypothermia .

The wind chill factor is calculated on the basis of ambient temperature and wind speed . In the event of wind, it gives an indication of the loss of heat by the body if the temperature is less than 50°F (10°C) . This is the formula which was adopted in January 2003 by the United States Federal Office for Meteorological Coordination withthe Meteorological Service of Canada (MSC), the US Department of Defence (DoD) and the United States National Oceanic and Atmospheric Administration (NOAA) .

Example: an ambient temperature of 0°F and a wind of 20 mph act on your body as if the temperature were -15°F!

Measuring cycle: 2 measurements per second with 0 .1°F/C resolutionMeasuring range: -99°F to 40°F (-37°C to 4°C) (above 40°F (4°C), the temperature shown is ambient temperature)Accuracy: +/- 1°F (0 .5°C)
