OVERVIEW
CAUTION
SETUP & FUNCTIONS
Your Kestrel brand Weather Tracker 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 which rely on either of these values. Before relying on a Kestrel Weather Weather Tracker 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 Tracker 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 (ie 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 Weather Tracker to make any
decisions regarding safety, health or property protection.
!
WARNING
To reduce the risk of injury or death to persons, read and follow these guidelin
es!
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.

BAROMETRIC PRESSURE & ALTITUDE SETUP
BLUETOOTH SETUP (BLUETOOTH ENABLED METERS ONLY)
To transfer your Kestrel’s real-time and logged data
wirelessly and automatically to a laptop or PDA, follow
these set up steps.
Setting Barometric Pressure & Altitude
The Kestrel meter measures “station pressure”, which
changes in response to both changes in altitude and
changes in atmosphere. Barometric pressure is a measurement of the air pressure adjusted to sea level. To obtain
accurate barometric pressure and altitude readings, you
must first know EITHER your location’s current barometric
pressure OR your current altitude.
Station pressure is displayed if the reference altitude is set to zero.
Be sure to adjust your reference measurements for altitude and/or
barometric pressure when you change your location or when there
have been dramatic changes in weather conditions.
OPTION 1
