CAUTION
!
Your Kestrel brand Weather 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 Kestrel Weather Meter readings, use care to either a) force air ow 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 signicant 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 Meter to make any
decisions regarding safety, health or property protection.
