Kestrel 4000 - Manual (Page 2)

Your Kestrel brand Weather & Environmental Meter is designed to provide accurate measurement of
current conditions only. Depending on your location and environment, conditions may change rapidly.
Rapid temperature and humidity changes (ie moving your meter from indoors to outdoors) may cause inaccurate readings
of temperature and humidity as well as all readings that rely on either of these values. Before relying on a Kestrel Meter's
readings, use care to either a) force air flow over the sensors by waving or slinging your meter through the air; or b) wait until
your unit’s readings have stabilized, indicating it has equilibrated to its 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 significant 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 extra 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!
The Heat Stress, Wind Chill and Thermal Work Limit indices are published indices developed by the National Weather Service
to provide decision guidance based on average human physiological response. Certain individuals, animals, equipment
or property may be more susceptible to harm relating to environmental conditions, requiring additional precautions. For
example, very young or elderly individuals, individuals with asthma or sickling trait, and individuals who have not become
acclimated to hot conditions are likely to be more prone to heat illness, heat exhaustion, heat stroke or death.
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 illness.
• Be prepared with supplies to treat heat illness.
• Have and practice a heat illness action plan.
Your Kestrel Weather & Environmental Meter is an environmental meter, not a medical device.
It is only one source of information and must be employed with care and good judgment.
