Kestrel®2000
Pocket Weather™Meter
Thank you for purchasing the Kestrel 2000 Pocket Weather Meter. This
instrument will measure the following environmental conditions:
• wind speed • temperature
• maximum wind gust • wind chill
• average wind speed
This instrument also features a data hold function, a backlight, and
an automatic power-down function. Every unit is fully tested at our
factory for measurement accuracy and waterproof integrity. The
one-year warranty can be extended to two years by simply filling
out the attached registration card.

1) Slide off cover. 2) Turn on: Press the center
button ( ) to turn on the unit.
3) Select operating mode. Press the right arrow ( ) to scroll
through the measurements listed below. Press the left arrow
() to scroll through the measurements in reverse order. The
instantaneous measurements will be displayed. (See
Understanding the Measurements section for more information.)
5) Hold mode. Press while holding to hold the measured
value on the display. The word “HOLD” will blink to indicate the
Hold Mode. Press or to view the other measurements in
Hold Mode. Press while holding to exit the Hold Mode.
This mode can be useful for taking measurements when unable
to view the display, as within a duct. The Max and Avg Wind
Speed Modes will continue to work as usual.
6) Turn on the backlight. Press to activate the backlight for 10
seconds. If or are pressed while the backlight is illuminated,
the backlight will remain illuminated for another 10 seconds.
Press while the backlight is illuminated to manually turn off
the backlight.
7) Turn off. Hold for 2 seconds to manually turn off the unit.
The unit will automatically turn off if no buttons have been
pressed for 45 minutes.
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.
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.
MAINTENANCE & TROUBLESHOOTING
StoringYour Kestrel
Avoid storing your Kestrel where it will be exposed to temperatures below
-30°C [-22°F] or above 80° C [176° 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 over 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.
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 wind
speed readings because the magnetic field applies both a braking and an
accelerating force which cancel each other.The impeller has been calibrated
to provide wind speed readings accurate to within at least ± 3%.
High Speed Use
After several hours of sustained operation over
25M/S (~49KT,90 KM/H,56 MPHor 4,923FPM),
theKestrel will lose some accuracy due to wear
of the sapphire bearings in the impeller.
4) Select the units of measure. Press while holding to scroll
through the units of measure.

BEAUFORT SCALE
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 the British
naval Commander Sir Francis
Beaufort (1774-1857) and is still
commonly used by mariners.
