User Screens
The Kestrel 4000 has three User Screens which can be customized to display three current
measurements simultaneously. (See page 10 for setup instructions.)
Min/Max/Avg for Wind Speed and Wind Chill
The Min/Max/Avg values for Wind Speed and Wind Chill are measured independently from the stored and charted
data. While viewing the Min/Max/Avg screen for either Wind Speed or Wind Chill, press the
button to begin
collecting data for both measurements. Press the
button again to stop collecting data and hold the values
on the display. Press the
button a third time to clear the data. This routine will work simultaneously for both
measurements, regardless of which one is displayed while the routine is run. The Min/Max/Avg for Wind Speed
and Wind Chill will not affect any other Min/Max/Avg or stored data.
Barometric Pressure and Altitude Adjustment
The Kestrel 4000 will measure air pressure in order to calculate barometric pressure and altitude. Changes in
either air pressure or altitude will affect these readings, so it's important to make adjustments as necessary.
Altitude Adjustment
Obtain a barometric pressure reading from a local weather source to use as your reference
pressure. From the Current Altitude Screen, press the
button to enter the adjustment
mode. Press the button to increase the reference pressure or the button to decrease
the reference pressure. You will notice that the Altitude will change with changes in the
reference pressure. Press the
button to exit the adjustment mode.
Pressure Adjustment
Obtain your altitude from a topographical map or landmark to use as your reference altitude.
From the Current Barometric Pressure Screen, press the
button to enter the adjustment
mode. Press the button to increase the reference altitude or the button to decrease
the reference altitude. You will notice that the Barometric Pressure will change with
changes in the reference altitude. Press the
button to exit the adjustment mode.
