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.
Now let’s assume that you are planning a day hike,and you’d like to track your altitude. Before starting,you’ll need to adjust the reference
pressure on the ALTITUDE screen. You can do this by simply adjusting the reference pressure until you reach the elevation of your
house. The reference pressure will be the same as the pressure reading on the BARO screen. You can now track the altitude changes
as you hike. You can ignore the values on the BARO screen,since the pressure changes are predominantly due to changes in elevation.
As with all altimeters, it must be assumed that any change in pressure due to weather is small over the course of one day. If you were
to 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.
Altitude Adjustment
Obtain a barometric pressure reading from a local weather source to use as your reference
pressure. From the Current Altitude Screen, press the button to enter the adjustment
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.
Pressure Adjustment
Obtain your altitude from a topographical map or landmark to use as your reference altitude.
From the Current Barometric Pressure Screen, press the button to enter the adjustment
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.
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 off and data log is full), or Off (Manual Store button has been disabled). See page 10 for more information
on Memory.
Backlight
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.

You can customize your Kestrel 4000 in multiple ways. Press the button to access the Main Setup Menu.
Press the button to select the highlighted setting.
Off - Press the or the button to turn the display off. Even when the Kestrel’s display is turned off, the unit
will continue to automatically store data at the defined Store Rate. Wind speed will NOT be stored when the unit
is off.To continously measure wind speed,turn the auto shutdown off (pg.12).The battery life will be decreased if data
is stored frequently. The only way to completely shut off the unit is to remove the batteries. Custom settings
and data will be stored when the batteries are removed.
Memory Options
- These settings control the data storage properties. Press the button to return to the
Main Setup Menu.

Measurements - Measurement screens can be hidden from the normal measurement navigation. For
example, if wind chill is not of interest, it can be hidden. Press the or button to toggle between ON and
OFF for each individual measurement. Press the or button to highlight the desired measurement.
Press the button to return to the Main Setup Menu.
Graph Scale - These settings control the chart limits of your meter. Depending on the conditions, the lower and
upper limits of the chart scale may need to be adjusted in order to get the best view of the data. Highlight the
desired measurement by pressing the or button. Select the highlighted measurement by pressing the
button. Press the or button to increase or decrease the value of the limits. Press the or button to
change between the upper and lower limits. Press the button to exit and return to the measurement selec-
tion screen. Press the button to return to the Main Setup Menu.
Units - The units of measure can be adjusted to best suit the application. The following units are available:
Wind Speed Temperature, Pressure Altitude,
m/s meters per second Dewpoint,Wet inHg inches mercury Density Alt.
km/h kilometers per hour Bulb Temp, Wind hPa hectopascals m meters
kt knots Chill & Heat Index psi pound per ft feet
mph miles per hour °C Celsius square inch
ft/m feet per minute °F Fahrenheit mb millibar
Bft Beaufort
Highlight the desired measurement by pressing the or button. Press the or button to scroll through
the available units. Press the button to return to the Main Setup Menu.
User Screens - The three User Screens can be reconfigured to display the most appropriate information for the
application. Only current measurements can be selected for the User Screens - Min/Max/Avg and Charts are not
available.
Highlight the desired User Screen by pressing the or button. Press the button to select the highlighted
User Screen. Press the and buttons to change lines, and the or button to scroll through the available
measurements for each highlighted line. Press the button to return to the User Screen Setup Menu. Repeat
above process for the other User Screens or press the button to return to the Main Setup Menu.

System - The display Contrast and Auto Shutdown can be reconfigured as required. The relative humidity and
pressure sensors can also be recalibrated. Press the and buttons to highlight the appropriate selection, and
the or button to adjust or select.
The Contrast can be adjusted for better visibility depending on the ambient lighting conditions. Press the or
button to increase or decrease the contrast from 0 to 20 (0 is lightest, 20 is darkest).
The display can be set to automatically turn off in order to conserve the battery life. Auto Shutdown will only occur
after the preset time has elapsed without any button presses. Press the or button to scroll through the Auto
Shutdown options (15 minutes, 60 minutes, Off ).
Baro Cal - The pressure sensor can be calibrated if necessary. It is extremely important to know the precise altitude
and mean sea level barometricpressure at the time of calibrating the sensor. First, set the reference altitude on
the BARO measurement screen to the known altitude (see Pressure Adjustment on page 9). Then adjust the
calibrating setting on the Baro Cal screen to the known mean sea level barometric pressure. Recalibration of this
sensor is not typically required, and it is not recommended that you recalibrate without speaking to an NK
technician.
Humidity Cal - The humidity sensor can be calibrated by“teaching”it the correct humidity. Some special equipment
is required for this calibration,including two hermetically sealed containers and saturated salt solutions. NK offers a
calibration kit, and instructions are available on www.nkhome.com. Recalibration of this sensor is not typically
required, and it is not recommended that you recalibrate without speaking to an NK technician.
