Press the button to increase the reference button to decrease the reference pressure.
Kestrel® 4300 Construction Weather Tracker 15 with present GPS technology, pressure altimeters remain more accurate for measuring altitude change. This is why airplanes still rely on pressure altimeters, not GPS. Setting Description Operation Finally, the DENSITY ALTITUDE screen is calculated from the absolute values of station pressure, relative humidity and temperature, and is not affected by the reference values entered in the BARO and ALTITUDE screens. Clear Log All stored data is cleared.
Kestrel® 4300 Construction Weather Tracker Measurements Measurement screens can be turned off, or “hidden” from the normal measurement navigation.

Kestrel® 4300 Construction Weather Tracker Heat Index A practical measure of how hot the current combination of relative humidity and temperature feels to a human body. Higher relative humidity makes it seem hotter because the body’s ability to cool itself by evaporating perspiration is reduced. Reference Pressure The local barometric pressure. Input to the altitude screen to provide correct altitude readings. Also known as the altimeter setting.
Kestrel® 4300 Construction Weather Tracker 29 FREQUENTLY ASKED QUESTIONS Why is my Kestrel Meter is not registering wind speed? How can a Kestrel 4300 help prevent plastic shrinkage cracks? It probably just needs a replacement impeller. You can verify this by removing the impeller (press firmly on the sides of the impeller), and turn the unit on to the wind speed screen. Hold the Kestrel Meter near a television, computer monitor or some electronic device and it will display a wind speed.
Kestrel® 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 specified 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.
