5) Measure wind speed, max and
average: Simply point the unit into
the air flow you wish to measure.
Measure tempe rature and wind
chill: The Kestrel's temperature sensor
is located in the right opening below
the impeller. Because it is external to
the case, you can take fast and accurate
measurements by simply waving the unit rapidly back and forth OR
holding it into an air flow of at least 1 M/S [2 KT, 4 KM/H, 2 MPH or 197
FPM] and reading the display immediately. (The air flow ensures that
the temperature sensor measures the temperature of the air, not the
case.) Alternatively, you can take accurate readings with no air flow
by allowing the case to reach the same temperature as the surrounding
air. (If the case is much warmer or cooler than the air, this can take up
to 30 minutes.)

Wind Speed Functions

Operating Modes: Moving 3-second average ( ), maximum 3-second
gust since power on (MAX) and average since power on (AVG).
Units: Knots (KT), meters per second (M/S), kilometers per hour (KM/H),
miles per hour (MPH), feet per minute (FPM) and Beaufort (B).
On-axis Accuracy: greater of ± 3% or ± least significant digit.
Off-axis Response: -1% @ 5°, -2% @ 10°, -3% @ 15°.
Calibration Drift: < 2% after 100 hours use at 7 M/S [~14 KT, 25 KM/H, 16
MPH or 1400 FPM].
Minimum Speed: 0.3 M/S [~0.6 KT, 1.0 KM/H, 0.7 MPH or 59.0 FPM].
Maximum Speed: 40 M/S [~78 KT, 144 KM/H, 89 MPH or 7877 FPM].

Temperature and Wind Chill Functions

Operating Modes: Temperature ( ), wind chill (
Units: Degrees Centigrade (°C) and degrees Fahrenheit (°F).
Accuracy: ± 1.0°C.
Minimum Temperature: -30°C [-22°F].
Maximum Temperature: 70°C [158°F].

Display

Temperature Limitations: Normal operation from -15°C to 60°C [-4°F to
140°F]. Below -15°C [-4°F], accurate readings may be taken by keeping
the unit warmer than -15°C [4°F] and exposing it for the minimum time
necessary to take a reading (less than one minute).

Storage Temperature: Prolonged exposure to temperatures below -20°C
[-4°F] or above 80°C [176°F] may cause permanent damage.

Physical

Impeller: 25 mm. [1 in.] diameter, sapphire bearings, light weight. User-
replaceable impeller/housing assembly.
