Kestrel 4000 Instruction Manual page 2

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
Use only AAA batteries. Install batteries as indicated on the battery door. After installing the
batteries, the Kestrel 4000 will automatically start in the Date and Time Setting mode. (See Date and
Time Setup below.) Custom settings and chart data will be saved during a battery change.
Turning the Kestrel 4000 ON and OFF
ON: Press the button.
OFF: Hold the button for two seconds. Or, press the
word OFF highlighted. (Note: your unit will continue to automatically store data when the power is
turned off.)
Date and Time Setup
The first time that you turn on your Kestrel 4000, 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
scroll through the settings. Press the and
setting options. After entering the date and time, press the
Date/Time Setup. Then press the button again to exit the Main Setup Menu.

the button to scroll through these screens in
reverse order.
Navigation of Charts
The Kestrel 4000 is capable of storing up to 250 data points. To review
the data, press the button while viewing a chart. A cursor will appear
on the most recent data point. Press the button to scroll through
older data points and the button to scroll through more recent data
points. The date and time at which the data was stored will be displayed
at the bottom of the screen. The data value will be displayed at the top of the screen. Hold down the
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.

Date & Time
The Kestrel 4000 is set up to display 10 Measurements (some are actually
calculations) in 3 Modes.
The Measurements are listed to the right with their corresponding screen
icon. Use the and buttons to scroll through the various Measurements.
The Modes are:
Current - displays the instantaneous reading
Min/Max/Avg - displays the Minimum/Maximum/Average readings from
stored data
Chart - displays a graphical representation of up to 250 stored data points
Examples of each of these screens are shown below. Use the
to scroll through the various Modes.
Current
In addition to these Measurements and Modes, there are also 3 User Screens, which simultaneously
show 3 current measurements (see pages 8 and 11 for more information); and the Date & Time Screen,
which gives the current date and time.

User Screens
The Kestrel 4000 has three User Screens which can be customized to display three current
measurements simultaneously. (See page 11 for setup instructions.)
Min/Max/Avg for Wind Speed and Wind Chill
The Min/Max/Avg values for Wind Speed and Wind Chill are measured independently from the stored and charted
data. While viewing the Min/Max/Avg screen for either Wind Speed or Wind Chill, press the
screen displays "--average" to begin collecting data for both measurements. Press the
screen displays "--stop" to stop collecting data and hold the values on the display. Press the
screen displays "--clear" to clear the data. This routine will work simultaneously for both measurements,
regardless of which one is displayed while the routine is run. The Min/Max/Avg for Wind Speed and Wind Chill
will not affect any other Min/Max/Avg or stored data.
Relative Humidity
For accurate measurements, keep the Kestrel 4000 in the shade. Allow the unit to sit in ambient conditions for
several minutes or wave the meter side-to-side for 15 seconds.
Barometric Pressure and Altitude Adjustment
The Kestrel 4000 will measure station pressure in order to calculate barometric pressure and altitude. Changes in
either air pressure or altitude will affect these readings, so it's important to make adjustments as necessary.
First, you will need to obtain either (a) the current barometric pressure or (b) the altitude of your location. You can
obtain your current barometric pressure by contacting a local airport or weather service. Set this value as your
reference pressure on the ALTITUDE screen to determine your altitude. Otherwise, you can obtain your altitude
from a topographical map or local landmark. Set this value as your reference altitude on the BARO screen to
or
determine your barometric pressure.
There are two basic examples for when and how to use the BARO and ALTITUDE screens. First, assume that you
know the altitude from one of the sources above. Set the reference altitude on the BARO screen to this elevation.
As long as you remain at home, you can accurately track changes in the barometric pressure. However, the
measurement on the ALTITUDE screen also changes. This value will fluctuate as pressure fronts pass through your
location. Since you know your house is not changing elevation, you can ignore this screen.
