APPLICATION EXAMPLES

This section provides examples of applications where a Kestrel Meter might be used, and the appropriate
memory settings.
Weather Monitoring
Auto Store On
Store Rate 1 hr
Overwrite On
Man Store Off
These settings will allow you to track conditions for 2 months. When the memory is full, each new
measurement will be stored in place of the oldest data point. The charts will provide a quick look at the
recent weather conditions. Keep an eye out for falling barometric pressure, which indicates that a storm
is coming.
Hiking/Camping for the Weekend
Auto Store On
Store Rate 20 min
Overwrite Off
Man Store On
These settings will allow you to track the conditions for almost 20 days. Measurements will be stored every
20 minutes, and stop storing when the log is full. This will let you review the trip at your convenience when
you return. You can also manually store the conditions, in case you get caught in 40 mile per hour winds or
make it to the top of a mountain. For more detailed information on your trip, set the Store Rate to 2 hours
overnight, and 10 minutes during the day.
Kestrel 4000 Pocket Weather Tracker
