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 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

turn o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 ow 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 ows 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 dened by the US National
Weather Service. Wind chill is the eective 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
Environmental
Every Kestrel Meter is fully waterproof and oats, and has passed mil-spec drop testing.
Storing Your Kestrel
Avoid storing your Kestrel where it will be exposed to temperatures below -30°C [-22°F] or
above 60° 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 becomes dim or disappears, replace the
battery. Use a large coin to open the battery compartment. Use
only new CR2032 coin cell batteries (available where watch
batteries are sold). Wipe the battery clean of any ngerprints
and insert the positive (+) pole up, angling the battery
downward and pressing it rmly into place. 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 that responds to the earth’s magnetic elds. This does not
aect the accuracy of the wind speed readings because the magnetic eld 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 numerous 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 pivot bearings in the impeller.

Replacing the Impeller
You may recalibrate the wind speed readings by replacing
the impeller. Press FIRMLY on the sides of the black impeller
housing with your thumbs to remove the entire assembly.
When inserting the new impeller, be sure the arrow is 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.
BEAUFORT SCALE
The Beaufort Scale is a system for estimating
wind force without the use of instruments
based on the visible eects 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.
