Kestrel

4500 Pocket Weather

Tracker

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.

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.

These settings will allow you to track all conditions for 46 hours. Chart your altitude changes, watch how

the temperature and humidity vary with altitude, and log your apparent speed. Data will no longer be

stored once the log is full, in order to preserve it until it can be reviewed later. Be sure to clear the data

log just before your flight.
