CAUTION
!
WARNING
!
Your Kestrel Weather/Environmental Meter is designed to provide accurate
measurement of current and historical conditions only. Depending on your
location and environment, conditions may change rapidly.
Rapid temperature and humidity changes (i.e., moving your meter from indoors to outdoors) may cause temporarily inaccurate readings
of temperature and humidity as well as all readings that rely on either of these values. Before relying on temperature readings from your
Kestrel Meter, be sure to let it equilibrate or force air ow over the sensors by waving or slinging your meter through the air. For Humidity
readings, wait until your unit’s readings have stabilized, indicating it has equilibrated to its new environment. Humidity readings may take
more than 15 minutes to equilibrate to a new environment.
To maximize the accuracy and reliability of your readings:
• Ensure that your Kestrel Meter is in good repair and within factory calibration.
• Take readings frequently and carefully according to the guidelines above.
• Allow your meter’s readings to stabilize after signicant changes in temperature or humidity (i.e., changing location from indoors
to outdoors).
• Allow a margin of safety for changing conditions and reading errors (2-3% of reading is recommended).
Use care and good judgment when referring to your Kestrel Meter to make any decisions regarding safety,
health or property protection.
To reduce the risk of injury or death to persons, read and follow these guidelines!
Your Kestrel Weather/Environmental Weather Meter may provide one or more of these measurements relating to estimation of danger of
injury to people or animals from heat or cold: Heat Stress Index, Wind Chill Index, Wet Bulb Globe Temperature (“WBGT”), Thermal Work
Limit (“TWL”). Note that guidance tables based on these values are based on typical physiological response. Certain individuals or animals
may be more susceptible to harm relating to environmental conditions and require additional precautions. For example, very young or
elderly individuals, individuals with asthma, and individuals who have not become acclimatized to hot conditions are likely to be more
prone to heat injury.
• Know yourself and the individuals and items you are responsible for.
• Where appropriate, seek the guidance of a medical professional.
• Know what to do in the event of heat or cold injury and be prepared with supplies.
• In the case of heat illness, remember the rule – “Cool rst, transport second.” An inexpensive ice bath can mean the dierence
between life and death.
Your Kestrel Weather/Environmental Meter is not a medical device. It is only one source of information and
must be employed with care and good judgment.

PROBABILITY OF IGNITION AND FINE DEAD FUEL MOISTURE
The Probability of Ignition (PIG) and Fine Dead Fuel Moisture
(FDFM, also known as Reference Fuel Moisture or 1 Hour Fuel
Moisture) measurements in the Kestrel Fire Weather Pro meters
come from the tables in the National Wildre Coordinating
Group, Incident Response Pocket Guide, 2014, with nighttime
measurements following the recommendation from the
National Wildre Coordinating Group, Fire Behavior Field
Reference Guide, 2014.
Setting User Inputs for PIG and FDFM
1. In the settings menu of the PIG Current Measurement
Screen, scroll to Shade and set it to match the shade
conditions of the location of interest.
2. Scroll to Aspect and set it to match the primary
direction the slope of the location of interest is facing.
Alternatively, the direction can be captured by selecting
Aspect and then scrolling to Capture and following the on
screen instructions. Hold the Kestrel vertically and face
the back of the Kestrel away from the slope face, then
press Select.
3. Scroll to Slope and set it to match the slope of the
location of interest.
4. Scroll to Fire Elevation and set it to match the relative
position of the location of interest.
Warning! It is important to ensure the Date and Time settings in your
Kestrel are correct when using PIG and FDFM measurements. After
removing the battery, Date and Time will need to be reset. If Date
and Time are not set correctly, PIG and FDFM measurements will be
incorrect.
Note! When the time set in the Kestrel is earlier than 08:00
or later than 19:59, The Shade Setting will be locked to
50%-100% per the recommendations in the Fire Behavior
Field Reference Guide. Between 08:00 and 19:59, Shade
will return to the previous value set by the user.
Note! When Temperature values are outside the extreme
high or low values listed in the PIG and FDFM tables, the
nearest extreme temperature value displayed on the table
will be substituted to derive PIG and FDFM.
Note! It is not necessary to set the Date and Time format
to 24 hour format when using PIG or FDFM.
Note! The Data Graph Screen for the PIG measurement
only displays a log of PIG measurements. FDFM
measurements are not logged.

Note: To highlight the severity of conditions, if the Red Warning
Zone is reached, the line indicating the current zone will ash. If
the Black Warning Zone is reached, the measurement value will
ash inverted.
Note: If an alert is activated, pressing on the WBGT
Measurement Screen will deactivate the alert until the next
higher threshold is reached or until the WBGT measurement dips
below the threshold and then raises above it again.
Note: In the Options Menu under Display, there is an Alerts
Test function which will activate the light and buzzer. When
using the unit in a new situation, test the alerts to familiarize
yourself with their intensity.
HOW TO MEASURE WBGT ACCURATELY:
» When changing environments (moving form an air
conditioned room to outdoors or removing the unit
from your pocket) the unit may require more than 15
minutes to equilibrate to its surroundings before taking
readings.
» Take measurements at least 3 feet o the ground and in
the same wind or air ow conditions as the people you
are monitoring. Ensure the Kestrel is oriented into the
wind and able to measure the full wind value. A tripod
or pole mount and the Kestrel Rotating Vane Mount are
ideal for ensuring accurate measurements.
» Dierences in the reectivity of ground surfaces such
as grass or asphalt will impact measurements. Be sure
to take measurements in the same solar/radiant heat
environment as the people you are monitoring.
1. POWER ON KESTREL. Press to power on Kestrel.
2. CONFIGURE WBGT SETTINGS.
1. Scroll to the WBGT Current Measurement Screen and
press select.
2. Set Type to either Indoor or Outdoor, depending

5. For information on setting custom threshold ag
settings see page13.
6. To receive light or buzzer alerts when WBGT is above
a zone threshold, scroll to and select Alerts… in the
WBGT Settings menu. You may set Light and Buzzer
individually. Selecting a zone for Light or Buzzer will
cause that alert to activate when conditions reach
the threshold for the selected zone.
Warning: In addition to monitoring WBGT values, please refer
to your state or organization’s requirements for measuring
WBGT, heat acclimatization guidelines, work/rest ratios and
water consumption.

If you do not wish to follow one of the WBGT guidelines
pre-loaded into the Kestrel Heat Stress Tracker, you may
set custom zones and zone thresholds. Your Kestrel Heat
Stress Tracker allows you to activate and set up to six
customized heat stress warning zones identied by color
names on screen.
SETTING CUSTOM WBGT ZONES:
1. In the Settings Menu of the WBGT Current
Measurement Screen, scroll to and select Zones.
2. Scroll to the colored zones you wish to edit and press
select. Editing any value from a preset guideline in
the Zone Settings Menu will automatically change the
name of the guideline to Custom.
3. In the Zone submenu you can turn zones on or o
by setting Status to ON or OFF as well as change the
lower temperature bound of the zone by adjusting the
Threshold value.
4. The threshold for a zone cannot be greater than the
zone above or less than the zone below it.
5. Zone thresholds cannot be adjusted if the Status is
set to O.
6. If the Status of a zone is set to OFF and the thresholds
of the zones above and below are set one tenth of a
degree apart (the minimum resolution available) the
Status of the intermediary zone cannot be set to On.
Warning: While the Kestrel LiNK app for mobile devices (compatible with
LiNK enabled units only) does have a threshold alerts feature, it does not
currently synch with the zone thresholds set in the Kestrel 5400 which
must be set separately.
CUSTOM FLAG SETTINGS
» The Kestrel’s compass is intended for measuring
wind direction. The Kestrel must be held vertically
with the back of the unit pointed towards the

The Kestrel employs a stable, accurate pressure sensor to
measure station pressure, the unadjusted air pressure in
your location.
» To use your Kestrel to measure barometric pressure
(station pressure adjusted for local elevation), you
must enter a correct reference value for your altitude.
Accurate barometric readings require that no elevation
changes be made while taking measurements.
» To use your Kestrel to measure altitude changes
(changes in station pressure associated with changes
in elevation), you must enter a correct reference
value for your starting barometric pressure. Accurate
altitude readings depend on stable, weather related
barometric air pressure while measurements are taken.
» Synched values between the Altitude and Barometer
measurement screens allow reference value updates
on either screen to automatically update reference
values on the other.
Note! You cannot use your Kestrel as a barometer and altimeter
simultaneously.

The Kestrel 5400 also displays a measure of human heat
stress known as “Thermal Work Limit,” or “TWL.” Unlike WBGT,
which is a measure of the environment, TWL is an estimate
of the cooling capacity of a human body in given conditions.
Accordingly, a higher TWL is safer because a person is able to
eliminate more heat from their body. TWL provides four work
level recommendations (Unrestricted, Acclimatization, Buer,
and Withdraw) to help guide work management in thermally
dangerous conditions.
