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 Tempe rature : 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
thecase,youcantakefast 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
byallowing the case to reach thesame temperatureas the surrounding
air. (If the case is much warmer or cooler than the air,this can take up
to 30 minutes.)

Storing Your Kestrel
Avoid storing your Kestrel where it will beexposed to temperatures below-20°C [-
4°F] or above 80° C [176° F] for extended periods of time. Doing so may
permanently damage the LCD, electronics, battery or enclosure. (Note that the
inside of a car parked in the hot sun can reach very high temperatures.) If the
temperature of the actual LCD of your unit exceeds 70° C [158° F],it will temporarily
become solid black until it cools down to below this temperature.
Use of the Lanyard and Cover
Your Kestrel is shipped with the slip-on cover captivated by the lanyard to prevent
loss. If you prefer to be able to remove the cover entirely, open the lanyard end
cap with a small screw driver,then remove the slip-lock. Slide the cover completely
off the lanyard,then reassemble the slip-lock and lanyard end cap as before.
Replacing the Battery
When your display grows dim or blank,
replace the battery. Use a large coin to open
the battery compartment. Insert a new
CR2032 coin cell (available wherever 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.
Why does the Impeller Appear
Imbalanced?
It is NORMAL for the impeller to oscillate as it comes to a stop. It is NOT
imbalanced. Rather, it contains a very small magnet which responds to the
earth’s magnetic fields. This does not affect the accuracy of the windspeed
readings because the magnetic field applies both a braking and an accelerating
force which cancel each other.The impeller has been calibrated to be accurate
to within at least ± 3%.
High Speed Use
After several hours of
sustained operation over 25
M/S (~49 KT, 90 KM/H, 56
MPH or 4,923 FPM), the
Kestrel will lose some
accuracy due to wear of the
sapphire bearings in the impeller assembly. If you require accurate high AND low
speed measurements,we recommend a second impeller.
Troubleshooting a Damaged Impeller
If the impeller rotates,but only “0”or “—” shows on the display, the impeller may
no longer be sending a signal to the unit. Test the unit by turning it on and placing
it near an electromagnetic source (i.e. back of computer monitor or TV). If the
display shows any number other than “0” or “—”, the unit does not need to be
returned but does need a new impeller assembly. Contact Nielsen-Kellerman
Australia, PTY Ltd. or your place of purchase to
order a replacement.
Replacing the Impeller
Press FIRMLY on the sides of the black impeller
housing with your thumbs to remove the entire
housing. When inserting the new impeller,
be sure the arrowis facing the display side
of the unit, and is aligned with the top of the
meter. Press on the sides of the housing
rather than the center.

The Beaufort Scale is a system for
estimating wind force without the use
of instruments based on the visible
effects of the wind on the physical
environment. The behavior of smoke,
waves, trees, etc., is rated on a 13 point
scale.The scale was devised in 1805 by
theBritish naval Commander Sir Francis
Beaufort (1774-1875) and is still
commonly used by mariners.

WIND CHILL
The Kestrel 2000 automatically calculates wind chill, which can provide useful
guidance when preparing for cold-weather outdoor activities. “Wind chill”provides
an indication of how cold it feels given the combined effects of the actual air
temperature and the wind speed.For more information about the derivation and
meaning of wind chill,visit www.nkhome.com.

What is a “ Kestrel”? The American Kestrel is the smallest North
American falcon. Beautiful and highly adaptable, it can be
found virtually everywhere in North America. It is unique
among falcons for its ability to both hover at very low speeds
and dive at very high speeds.
