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
aect 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 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.
