4300 Construction Weather Tracker
liquid crystals will freeze and not display a reading. Even in these conditions, your Kestrel Meter will still
continue to measure and record readings as specifi ed by the automatic and manual data storage rates,
you will just not be able to read the display until the environment’s temperature is within the operational
range. In cold environments, you can keep the Kestrel Meter warm in your pocket and remove it only to
take readings. Be sure to wave the unit back and forth to create airfl ow over the sensors to ensure the most
accurate reading possible.
Why doesn’t my Kestrel Meter match the local Weather Report?
Obtaining a weather report from a local television station, airport or internet site will give you the weather
where those instruments are, which is not necessarily the same as where you are. Your Kestrel Meter is
measuring the conditions right where you are. The nature of microclimates and weather fronts is that they
are varied, and even locations as close as a mile apart can have diff erent weather readings. You can certainly
use these weather reporting services for good estimates of what the conditions will be, but for the most
accurate readings at your particular location, the Kestrel Meter is better.
