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
Storing Your 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
(See
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%.
