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
Type: Reflective 3½ digit LCD.
Digit Height: 9 mm. [0.36 in.].
Update: 1 second.
Range and Resolution: Depends
on measurement scale selected –
see chart:
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).
Auto Shutdown: 30 minutes after last key press.
Environmental
Buttons: Two sealed tactile rubber buttons control all functions.
Battery: User-replaceable CR2032 coin cell. Typical life, 800 hrs.
Sealing: Electronics enclosure IP67 – water resistant to 1 m. [3 ft.]. Floats.
Shock: Drop tested to 2 m. [6 ft.].
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.
Temperature Sensor: Hermetically sealed precision thermistor.
Case: Slip-on case prevents damage to display and moving parts.
Dimensions: 122 x 42 x 14 mm. [4.8 x 1.7 x 0.6 in.]; case, 117 x 46 x 19 mm. [4.6 x 1.8
x 0.7 in.]; lanyard, 0.5 m. [10 in.].
Weight: Unit, 43 g. [1.5 oz.]; case, 23 g. [0.8 oz.].
5) Measure wind speed, max and average: Simply point the unit into the
air flow you wish to measure.
Measure temperature 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.)
