Congratulations on the purchase of your Kestrel 4500 Pocket Weather Tracker! The Kestrel 4500 is our
newest and most comprehensive weather meter. It not only measures EVERY environmental condition
easily, accurately, and right in the palm of your hand, but now also integrates a digital compass to
indicate wind direction, cross wind and headwind/tailwind.
While the Kestrel 4500 is user-friendly and simple to use, reading the instruction manual is
recommended in order to use the Kestrel 4500 to its fullest potential.
NK, manufacturer of Kestrel Pocket Weather Meters, is available to answer questions
and provide support. Contact NK by phone: [phone], fax: [phone], email:

GETTING STARTED
Pouch and Lanyards
Wrist and neck lanyards and a small pouch have been provided. To install the
lanyard, feed the thin end of the lanyard around the metal post on the battery
door (as shown in diagram). Feed the thick end of the lanyard through the loop
on the thin end. Using tweezers can help.
Battery Installation
AAA batteries have a magnetic signature that is strong enough to inuence compass readings. In
order to negate the batteries eect, it is important that the Kestrel 4500’s batteries remain in the same
orientation as they were when the unit was calibrated. To accomplish this, the Kestrel 4500 has a exible
plastic shim that slides in between the two batteries to keep them in place. Insert the batteries in the
orientation indicated on the battery door, then insert the shim between the new batteries with the clear
tab out and folded toward the end of the battery with the positive pole (the “bump”) pointing up. Press
the tab down over the battery with the “bump” through the hole (it will not remain completely at).
Close the door tightly. When changing the batteries, lift the clear tab folded over the positive pole of
the battery, remove the shim, and then remove the batteries and replace them with new ones. Please be
careful when changing batteries not to lose the shim!
After installing the batteries, the Kestrel Meter will automatically start in the Date and Time Setting
mode. (See Date and Time Setup.) Custom settings and chart data will be saved during a battery change;
only the date/time and MMA values will be lost.
Turning the Kestrel Meter ON and OFF
To turn the Kestrel Meter ON, press the button. To turn the Kestrel Meter OFF, hold the button for
two seconds. Or, press the button, then press the button with the word OFF highlighted. (Note:

Kestrel®4500 Pocket Weather®Tracker
your unit will continue to automatically store data when the power is turned o.) When rst turned on,
the Kestrel Meter will display a splash screen displaying the model number, the battery indicator, and
the code version. This battery indicator will indicate the percentage of battery life remaining, which is
helpful in preventing unexpected dead batteries.
Date and Time Setup
The rst time that you turn on your Kestrel Meter, as well as after a battery change,
you will need to set the date and time. The Introduction Screen will appear for 3
seconds, followed by the Date/Time Setup Screen. Press the and buttons to
scroll through the settings. Press the and buttons to scroll through the setting
options. After entering the date and time, press the button to exit the Date/Time
Setup. Then press the button again to exit the Main Setup Menu.
Calibrating the Digital Compass
Due to the magnetic signature of the AAA batteries, the Kestrel 4500’s digital compass must be
calibrated, or “taught” to correct for the magnetic eld of the batteries. This must be done each time the
batteries are changed or the battery door is opened. If your unit has not been calibrated, it will display
“uncalibrated”at the base of the Direction, Crosswind and Headwind screens and will not display or log
any values until it has been calibrated.
When calibrating the compass, be sure to choose a location that is not near metal or magnetic materials.
For example, you cannot calibrate the Kestrel Meter reliably on a metal desk. Also, keeping the Kestrel
Meter vertical (front/back and left/right) is crucial to accurate calibration. The foam stand included in the
Kestrel Meter’s packaging will help to stabilize the unit during calibration. (The piece is also handy for
standing the Kestrel Meter up while taking readings in the eld.) Finally, removing the impeller during
calibration is recommended. (Simply press on the edges of the impeller to pop it out, then press it back

7
in after calibration is complete. Align the small triangle on the impeller housing with the matching
triangle near the hinge of the impeller cover on the front of the unit.)
To calibrate the unit’s digital compass, press the button to enter into the Main Menu, and use the
button followed by the button to select System. In the System menu, select “Compass Cal.” Following
the screen prompts, place the Kestrel Meter in the foam stand and slowly spin it around three full times.
Each rotation should take approximately 10 seconds.“Cal Complete”will be displayed on the screen
when the calibration is nished. Press the button to exit out of the Menus.
After calibrating, you may wish to verify the digital compass’accuracy with a compass that you know to
be operating properly. Being careful to orient the Kestrel Meter vertically, verify the readings at north,
south, east and west. (It is possible that some but not all of the directions would be correct if the unit is
not calibrated correctly.) Remember to hold the Kestrel Meter and the compass far enough away from
each other that they do not interfere. You should expect the Kestrel Meter’s readings to be within ±5°
of the reference compass or better. If the Kestrel Meter’s direction readings do not appear to be correct,
simply run the calibration routine again.
Once your unit is correctly calibrated, you do not need to calibrate again unless a) you change the
batteries or open the battery door; b) the unit displays “uncalibrated” at the base of the Direction,
Crosswind or Headwind screen.
Calibration Error Messages
There are three error messages you may see during calibration. They are:
Magnetic Batteries: In some instances, the magnetic eld of the batteries is such that the Kestrel Meter
cannot accurately calibrate the compass. If this is the case, upon completion of the three rotations the
screen will display this error message. Simply open the battery door, rotate one or both of the batteries
slightly, and run the calibration again.

Kestrel®4500 Pocket Weather®Tracker
Too Slow: The unit was spun too slowly during the calibration routine. Press the button to remove the
error screen, and then follow the directions on the screen to calibrate.
Too Fast: The unit was spun too quickly during the calibration routine. Press the button to remove the
error screen, and then follow the directions on the screen to calibrate.

The Modes are displayed below. Use the and buttons to scroll through the various Modes. From any
mode, you may still scroll to a dierent Measurement by pressing the and buttons.
Current - Displays the instantaneous reading.
Min/Max/Avg - Displays the Minimum/Maximum/Average readings from stored data. If there is no
stored data, the values will be displayed as --.-.
Chart - Displays a graphical representation of up to 1400 stored data points for each measurement. If
there is no stored data, the axis will appear, but the chart will be blank. (See the following section for
information on Chart Navigation.)
Modes use and
Note: The Direction chart will display the logged direction in degrees, with the base line of the chart
representing 0° and the top of the chart representing 360°. The crosswind and headwind charts will
have the same graph scale as the wind speed chart. The graph scale can be adjusted in the Main Menu if
necessary to ensure that your logged values are displayed on screen.
Navigation of Charts
The Kestrel 4500 is capable of storing up to 1400 data points for each measurement. To review the data,
press the - button while viewing a chart. A cursor will appear on the most recent data point. Press the
and buttons to scroll through the data points. The date and time at which the data was stored will be
Modes use and

Kestrel®4500 Pocket Weather®Tracker
displayed at the bottom of the screen, and the data value will be displayed at the top of the screen. Hold
down the or button to scroll quickly through the data points.
Press the or button to review the data for the other measurements. Please note that the cursor will
remain at the same date and time. If new data is stored while viewing chart data, the entire chart will
shift left with the new data point charted on the right. The cursor will not shift with the chart.
Press the button to return to the Chart Mode.
SPECIAL FUNCTIONS
User Screens
The Kestrel Meter has three User Screens that can be customized to display three
current measurements simultaneously. These screens can also be turned o. (See the
Main Menu section for setup instructions.)
Max/Avg for Wind Speed, Direction, Headwind/Tailwind, Crosswind & Wind Chill
The Max/Avg values for the Wind Speed and Direction values are measured independently from the
stored and charted data. (The Direction measurement does not record the Max and Average since it is
not applicable, and will display N/A on the Min/Max/Avg screen.)

This allows the user to start and stop the averaging period in the most appropriate manner for their
application. Averaging on all wind-related values (Wind Speed, Crosswind, Headwind and Wind Chill)
will be started and stopped together.
While viewing the Min/Max/Avg screen for any of these measurements, hold the unit into the wind, and
press the button when the screen displays “--average”to begin collecting data for all measurements,
and again when the screen displays “--stop” to stop collecting data and hold the values on the
display. Press the button when the screen displays“--clear” to clear the data. This routine will work
simultaneously for all measurements, regardless of which one is displayed while the routine is run. The
Max/Avg for these wind values will not aect any other Min/Max/Avg or stored data.
Manual Data Storage
To manually store data, press the button. One of the following will appear: Data Stored (data has
been captured and will appear on chart), Full (Overwrite is o and data log is full), or O (Manual Store
button has been disabled). (See the Main Setup Menu section for more information on memory.)
Backlight
The Kestrel Meter has a high-visibility green backlight, which makes the display easily read in low-light
conditions.The Kestrel 4500 NV has a night-vision preserving backlight which helps users to sustain
natural night vision. The NV’s backlight incorporates an optical lter to reduce overall brightness and
minimize blue and green spectrum light to preserve night vision. Additionally, the backlight is much
dimmer than a standard backlight, making it more dicult to detect with the naked eye in night
operations. This backlight appears soft greyish pink (not red) and is still in the visible spectrum, so it is
not compatible with night-vision equipment.
It takes 30 to 45 minutes for the average eye to adapt to darkness and maximize night vision. Even a
short burst of white, yellow, green or blue light “bleaches out” the rod cell photoreceptors in the eye

Kestrel®4500 Pocket Weather®Tracker
and causes night blindness until the entire adaptation process can take place again. Light in the red
spectrum does not cause this “bleaching out”, preventing night blindness and night vision fatigue.
Press the button to activate the backlight. The light will remain activated for one minute. Press the
button within one minute to deactivate the light manually.
Measuring Direction
Before you begin, there are three simple things that are important to understand before using the
Kestrel 4500 to take compass readings:
1. Because the Kestrel 4500 is designed primarily to measure wind direction, the digital compass
component is aligned to work with the Kestrel Meter held vertically, in the same orientation used
when measuring wind. As is the case with all compasses, the compass component must be level to
yield accurate readings. To maximize the accuracy of compass readings, the Kestrel 4500 must be
positioned as close to the vertical as possible (front/back and left/right) when using any compass-
related feature (direction, crosswind, headwind, calibration). For every degree o vertical that the
unit is positioned, compass readings may vary up to three degrees.
2. The Kestrel Meter uses two AAA batteries to power the unit. These batteries have a magnetic
signature that can inuence the compass readings if not properly calibrated. After installing or
replacing the batteries, you must execute the simple self-calibration routine (see the Calibrating the
Digital Compass section) to ensure that the eect of the batteries is negated. If your unit has not
been calibrated, it will NOT measure direction and will post the message “uncalibrated”at the base
of any direction screen.
3. The impeller of the Kestrel 4500 also contains a small magnet that may slightly inuence the
compass readings when the impeller is still or rocking slightly. For maximum accuracy of compass
readings, the impeller should be spinning (or removed).

13
Taking a Compass Reading
To take a compass reading, simply hold the unit vertical and point the BACK of the unit toward the
direction that you wish to measure. (You can sight through the sensor opening to conrm the direction
alignment.) The unit will display the cardinal direction and degrees.
True vs. Magnetic North - Entering Variation/Declination
“True north”is the northern axis of rotation of the Earth. It is the point where the lines of longitude
converge on maps. “Magnetic north” is the point on the Earth’s surface where its magnetic eld points
directly downwards. Magnetic north does not exactly coincide with true north, and its location changes
over time. The dierence between Magnetic North and True North is called “Declination” or “Variation”.
These values for your location can be obtained on the internet. The NOAA website is an excellent
resource for this information: www.ngdc.noaa.gov
The Kestrel 4500, just like any other compass, will measure Magnetic North. However, True North can
be displayed by simply programming the Variation for your location. When viewing the Direction in
Magnetic North mode, the display will show “Magnetic North” below the reading. When viewing the
Direction in True North mode, the display will show“True N #.# E”, where #.# is the variation setting.
To switch between these modes, press the button. Then use the and buttons to toggle between
Magnetic and True. To enter the variation for your location, press the button to highlight Variation,
then and to adjust the value.
Measuring Crosswind & Headwind/Tailwind
The Kestrel 4500 automatically calculates crosswind or headwind with respect to a runway or target
direction. To use either of these screens, you must rst set the “heading”, or direction of the runway or
target as described below. You then measure the wind in the normal way, pointing the Kestrel into the

Kestrel®4500 Pocket Weather®Tracker
wind. The large number shown on the display will be the eective Crosswind or Headwind (depending
on the screen selected) for the target direction.
Note: Tailwinds are displayed as negative values on the Headwind screen. The full value wind speed and
direction are displayed below the Crosswind or Headwind for reference.
To enter the runway or target heading, press the button while on the Crosswind or Headwind screen.
The adjustment screen will always display the Magnetic North heading along the top, even if you have
the Kestrel set to True North. (If you selected True North mode in the Direction screen, this selection will
still be preserved when you return to the Direction screen.) Use the and buttons to select Auto Set
or Manual Set, and the button to enter the selection of your choice, then follow the instructions on
the screen to set the Magnetic Heading either automatically or manually.
- Auto Set allows you to point the Kestrel down the runway or in the direction of the target, and it
automatically enters the reference heading. Point the Kestrel down the runway or target, and press
the button.
- Manual Set allows you to enter the known heading of the runway or target. In Auto Adjust, follow
the prompts on the screen to have the Kestrel automatically set the heading. Use the and
buttons to enter the runway or target heading. Press the button to enter the selection of your
choice.
Relative Humidity
The Kestrel Meter is capable of measuring RH to a high accuracy: +/- 3% RH between 5 and 95%. To
ensure operation within these specications, please follow these recommendations:
• Avoid taking measurements in direct sunlight, which will heat the air inside the humidity sensor
enclosure and cause inaccurate readings.

15
• If your circumstances force you to expose the Kestrel Meter to a large temperature swing prior to
taking a relative humidity reading (such as when taking a Kestrel Meter stored inside at 70° F outside
to a temperature of 40° F), you will need to take additional steps to ensure that the Kestrel Meter’s
external temperature sensor is in thermal equilibrium.
- Ideally, provide an airow of at least 1 M/S (2.2 MPH), over the temperature sensor - point the
Kestrel Meter into the airow. If there is no airow, simply wave the unit back and forth so air
passes over the sensors. With airow over the temperature sensors and humidity chambers,
readings within specications will be provided within two to three minutes, even after a large
temperature shift.
- If no airow can be provided, you must allow sucient time for the RH value to stabilize. This
can take as long as 20 minutes- the greater the temperature change, the greater the time. You
can use the logging capability of the Kestrel Meter to conrm that the unit has stabilized to
a correct reading: Set the memory options to a relatively short logging interval (20 seconds
works well), select the graphical display of RH, and you can see when the value is no longer
changing signicantly. At that point, the RH value is stable and can be relied upon to be within
the accuracy specications.
Barometric Pressure and Altitude Adjustment
The Kestrel Meter measures “station”pressure—the actual air pressure in the measurement location—
and uses this value to calculate barometric pressure and altitude. Station pressure changes in response
to two things—changes in altitude and changes in the atmosphere. Because the Kestrel Meter is
constantly changing location and altitude, it is important to enter adjustments or “references” when
accurate pressure and altitude readings are needed.

Kestrel®4500 Pocket Weather®Tracker
Barometric pressure is station pressure corrected to sea level. In order to make the correction, the Kestrel
Meter needs an accurate reference altitude. Altitude is the height above sea level. In order to correctly
calculate altitude, the unit needs an accurate barometric pressure reference, also known as an “altimeter
setting”. Fortunately, you only need to know ONE of these values (current barometric pressure or current
altitude) in order to set your Kestrel Meter up to show accurate readings.
Starting with the known barometric pressure for your location
You can obtain your current barometric pressure by checking an internet weather
site for a nearby location, or contacting a local airport. Set this value as your reference
pressure on the ALTITUDE screen to determine your correct altitude: Press the
button to enter the reference setting mode. Press the button to increase the
reference pressure or the button to decrease the reference pressure. You will notice that the altitude
will change with changes in the reference pressure. Press the button to exit the adjustment mode.
Set your Kestrel Meter down on a table and allow the altitude reading to stabilize. (Note: very small
changes in pressure generate noticeable changes in altitude. In order to provide meaningful readings
for activities where altitude changes quickly, the Kestrel Meter features rapid altitude response. This is
why the altitude readings tend to uctuate by a few feet.) After obtaining a current altitude from the
ALTITUDE screen, move to the BARO screen and enter this value as your reference altitude by following
the same procedure. Both readings will now be accurate.
Starting with a known altitude for your location
You can obtain your altitude from a topographical map or local landmark. Google
Earth is an excellent free program that provides the exact altitude for any given
address: www.earth.google.com/. Set this value as your reference altitude on the
BARO screen to determine your barometric pressure: Press the button to enter

17
the reference setting mode. Press the button to increase the reference altitude or the button to
decrease the reference altitude. You will notice that the barometric pressure will change with changes in
the reference altitude. Press the button to exit the adjustment mode. Again, allow the Kestrel Meter to
stabilize, then enter the value from the BARO screen as your reference pressure on the ALTITUDE screen
by following the same procedure. Both readings are now accurate.
When reviewing stored data, remember that changes in pressure AND changes in location/altitude will
aect the stored values. When tracking pressure changes relative to weather, set the reference altitude
on the BARO screen and keep the Kestrel Meter in one location. Your graph history will now show trends
in barometric pressure. Your altitude as shown on the ALTITUDE screen will change as the weather
changes, but you can ignore this screen for this purpose.
If you are planning a day hike would like to track your altitude, you’ll need to enter the correct reference
pressure on the ALTITUDE screen as described above in“starting with the known barometric pressure.”
You can now track the altitude changes as you hike. In this instance, you should ignore the values on the
BARO screen, since the pressure changes will be due to changes in elevation far more than to changes in
the weather.
In general, changes in barometric pressure associated with weather changes are small over the course
of one day, but they will aect the accuracy of the altimeter over time. This is why aircraft reset their
altimeters at every aireld by entering the eld’s “altimeter setting” or reference pressure. Accordingly,
if accurate altitude readings are your primary interest, you should reset the reference pressure on your
Kestrel Meter regularly. If you encounter an elevation landmark, you can adjust the reference pressure
until the altitude matches the landmark elevation. This will correct the altitude for any pressure changes
due to the weather. (Or, you can obtain an updated reference pressure from the sources described
above.)

Kestrel®4500 Pocket Weather®Tracker
Some nal notes - If you wish to know the actual or station pressure for your location (such as for
engine tuning), simply set the reference altitude on the BARO screen to “0”. In this case, the Kestrel
Meter will not make any adjustment and will display the measured value. (Engine tuning and ballistics
software sometimes refer to atmospheric or station pressure as “absolute pressure.” These applications
are concerned with the actual air density, as opposed to pressure gradients relating to weather, so
barometric pressure is less useful.)
Also, the above discussion applies to ALL pressure altimeters, including one you may have in a watch or
other device, but not to GPS altimeters, which use satellite triangulation to determine altitude. Note that
with present GPS technology, pressure altimeters remain more accurate for measuring altitude change.
This is why airplanes still rely on pressure altimeters, not GPS.
Finally, the DENSITY ALTITUDE screen is calculated from the absolute values of station pressure, relative
humidity and temperature, and is not aected by the reference values entered in the BARO and
ALTITUDE screens.
