GETTING STARTED
Pouch and Lanyards
Wrist and neck lanyards and a small pouch have been provided. To install the lanyard,
feed the thin end of the lanyard around the metal post on the battery door (as shown
in diagram). Feed the thick end of the lanyard through the loop on the thin end. Using
tweezers can help.
Battery Installation
Use only AAA batteries. Install batteries as indicated on the battery door. After installing
the batteries, the Kestrel 4200 will automatically start in the Date and Time Setting mode. (See Date and
Time Setup below.) Custom settings and chart data will be saved during a battery change; only the date/
time and MMA values will be lost.

To turn the Kestrel Meter ON, press
the button. To turn the Kestrel Meter OFF, hold the
button for two
seconds. Or, press the
button, then press the
button with the word OFF highlighted. (Note: your unit
will continue to automatically store data when the power is turned off .) When fi rst turned on, the Kestrel
Meter will display a splash screen displaying the model number, the battery indicator, and the code version.
This battery indicator will indicate the percentage of battery life remaining, which is helpful in preventing
unexpected dead batteries.

SPECIAL FUNCTIONS
User Screens
The Kestrel Meter has three User Screens that can be customized to display three
current measurements simultaneously. These screens can also be turned off . (See the
Main Menu section for setup instructions.)
Max/Avg for Air Flow, Air Velocity & Wind Chill
The Max/Avg values for Air Flow, Velocity and Wind Chill are measured independently
from the stored and charted data. This allows the user to start and stop the averaging period in the most
appropriate manner for their application. Averaging on all velocity-related values (air fl ow, air velocity and
wind chill) will be started and stopped together.
While viewing the Min/Max/Avg screen for any of these measurements, hold the unit into the wind, and
press the
button when the screen displays “--average” to begin collecting data for all measurements, and
again when the screen displays “--stop” to stop collecting data and hold the values on the display. Press
the
button when the screen displays “--clear” to clear the data. This routine will work simultaneously
for all measurements, regardless of which one is displayed while the routine is run. The Max/Avg for these
velocity values will not aff ect any other Min/Max/Avg or stored data.
Manual Data Storage
To manually store data, press the
button. One of the following will appear: Data Stored (data has been
captured and will appear on chart), Full (Overwrite is off and data log is full), or Off (Manual Store button
has been disabled). (See the Main Setup Menu section for more information on memory.)
