These settings will allow you to record a detailed account of your jump. Be sure to clear the data log just
before jumping. As you descend toward the ground, you will be tracking the altitude every two seconds, as
well as the conditions at that altitude. The chart will clearly show the point at which the parachute opens, as
well as the point you get back on the ground.

These settings will record conditions every fi ve minutes, for a total storage of almost 6 days. You can
monitor the conditions in a laboratory or manufacturing plant, both day and night, to determine if the
climate control is working properly. Or you can examine the eff ect on the environment when employees
enter and exit the building.

These settings will require you to press the Manual Store Button in order to store any data at a duct, hood,
vent, or other air system. The meter will not store any data automatically. Be sure to record the location and
date/time of storage for reference when reviewing the data. After storing the conditions at each location,
simply review the data and balance the system.

GLOSSARY
The below defi nitions have been greatly simplifi ed in order to keep this section brief. We strongly
recommend that anyone who wishes to make use of these measurements refer to one of the many
excellent weather references available for a more in-depth defi nition.
On the internet, visit www.usatoday.com or www.noaa.gov. Or, locate the USA Today publication,
The
Weather Book
. Please note that any words in a defi nition printed in
italics
are themselves defi ned in this
glossary.
Altitude
The distance above sea level. The Kestrel Meter calculates altitude based on the measured
station pressure
and the input
barometric pressure
- or “reference pressure”.
Barometric Pressure
The air pressure of your location reduced to sea level. Pressure will change as weather systems move into
your location. Falling pressure indicates the arrival of a low pressure system and expected precipitation or
storm conditions. Steady or rising pressure indicates clear weather. A correct altitude must be input for the
Kestrel Meter to display barometric pressure correctly.
Density Altitude
The
altitude
at which you would be, given the current air density. Often used by pilots in order to determine
how an aircraft will perform. Also of interest to individuals who tune high performance internal combustion
engines, such as racecar engines.
Dewpoint
The
temperature
to which air must be cooled in order for condensation to occur. The diff erence between
dewpoint
and
temperature
is referred to as the “temperature/dew point spread”. A low dewpoint spread
indicates high
relative humidity
, while a large dewpoint spread indicates dry conditions.
