FREQUENTLY ASKED QUESTIONS
How do I set my Kestrel Meter to read the correct barometric pressure and altitude?
To measure these values accurately, you must know either your current pressure or altitude. If you know
the current barometric pressure, go to the altitude screen, and press the button to enter the reference
pressure. As you adjust the reference pressure, you will notice that the altitude will change. Once the
reference pressure is entered, note the new altitude, and go to the barometric pressure screen. Press the
button to enter this altitude as the reference altitude. Your Kestrel Meter is now displaying the accurate
pressure and altitude. (If you start with a known altitude, simply start with entering this value as the
reference altitude on the barometric pressure screen. The adjust the reference barometric pressure on the
altitude screen.)
You will need to update the reference pressure and altitude as you change altitude or the weather changes.
For more information on this topic, see the Barometric Pressure and Altitude Adjustment section under
“Special Functions.”
Why is my Kestrel Meter is not registering wind speed?
It probably just needs a replacement impeller. You can verify this by removing the impeller (press firmly
on the sides of the impeller), and turn the unit on to the wind speed screen. Hold the Kestrel Meter near a
television, computer monitor or some electronic device and it will display a wind speed. Or, wave a magnet
(like a refrigerator magnet) back and forth by the Kestrel Meter. If the Kestrel Meter is working properly,
you will register a wind speed reading, even though there is no impeller installed. Simply purchase a new
impeller and your Kestrel Meter’s wind speed readings will be restored to factory calibration.
What is the best way to take accurate temperature and humidity readings?
Avoid taking measurements in direct sunlight, and be sure there is airflow over the sensors. Especially if you
expose the Kestrel Meter to a large temperature swing prior to taking a reading (such as taking a Kestrel
Meter from the indoors to the outdoors in the winter), airflow over the sensors is necessary to measure
