UNDERSTANDING THE MEASUREMENTS Wind Speed - average over the previous three seconds. The measurement will be accurate for air flow through the front or rear of the unit. Maximum Wind Gust - maximum 3 - second wind speed since the unit was turned on. Average Wind Speed - average wind speed since the unit was turned on. Temperature - instantaneous temperature of the thermistor, which is located at the end of the long coiled leads in the open cavity below the impeller. The exposed thermistor will respond quickly to changes in temperature when air flows past it. For fastest response, either hold the unit into the wind or wave the unit side to side for 15 seconds. Readings should be taken in the shade. Water and snow temperatures can be taken by hold the unit in the water or snow. Wind Chill - combination of wind speed and temperature, as defined by the US National Weather Service. Wind chill is the effective temperature on a human or animal at low temperatures due to wind speed. Wind chill readings will be the same as the temperature readings above 45ºF or below 3 mph. Altitude and Barometric Pressure - the Kestrel 2500 will measure station pressure in order to calculate barometric pressure and altitude. Changes in either air pressure or altitude will affect these readings, so it’s important to make adjustments as necessary. First, you will need to obtain either (a) the current barometric pressure or (b) the altitude of your location. You can obtain your current barometric pressure by contacting a local airport or weather service. Set this value as your reference pressure on the ALTITUDE screen to determine your altitude. Otherwise, you can obtain your altitude from a topographic map or local landmark. Set this value as your reference altitude on the BAROMETRIC PRESSURE screen to determine your barometric pressure. There are two examples for when and how to use the BAROMETRIC PRESSURE and ALTITUDE screens. First, assume that you know the altitude from one of the sources above. Set the reference altitude on the BAROMETRIC PRESSURE screen to this elevation. As long as you remain at home, you can accurately track changes in the barometric pressure. However, the measurement on the ALTITUDE screen also changes. This value will fluctuate as pressure fronts pass through your location. Since you know your house in not changing elevation, you can ignore this screen. Now let’s assume that you are planning a day hike and you’d like to track your altitude. Before starting, you’ll need to adjust the reference pressure on the ALTITUDE screen. You can do this by simply adjusting the reference pressure until you reach the elevation of your house. The reference pressure will be the same as the pressure reading on the BAROMETRIC PRESSURE screen. You can now track the altitude as you hike. You can ignore the values on the BAROMETRIC PRESSURE screen, since the pressure changes are predominantly due to changes in elevation. As with all pressure altimeters, it must be assumed that any change in pressure due to weather is small over the course of one day. If you were to encounter an elevation landmark, you can adjust the reference pressure until the altitude matches the landmark elevation. This will correct the altitude for any pressure changes due to weather. MAINTENANCE Storing Your Kestrel Avoid storing your Kestrel where it will be exposed to temperatures above 80° C [176° F] or below -30°C [-22°F] for extended periods of time. Doing so may cause permanent damage. (Note that the inside of a car parked in the hot sun can reach very high temperatures.) Use of the Lanyard and Cover The cover can be captured on the lanyard to avoid loss. First, remove the cord poplock. Then feed the lanyard end through the large opening in the cover and out the slot. Replace the poplock on the lanyard. Replacing the Battery When your display flashes the low battery indicator ( ) , replace the battery. Use a large coin to open the battery compartment. Insert a new CR2032 coin cell (available where watch batteries are sold), positive (+) pole up. When replacing the battery door, be sure to keep the black rubber o-ring seated in the groove on the case back. Kestrel ® 2500 Pocket Weather ™ Meter with Backlight + CR2032 3V !
