In addition to Wind Speed and Wind Chill, the
kestrel
with Applied Ballistics software
also measures
Direction, Headwind/Tailwind and Crosswind.
Digital Compass Calibration
The
Kestrel meter's
digital compass must be calibrated
to correct for the AAA batteries’ magnetic field. It must
be re-calibrated every time the battery door is opened,
and it will not display or log any direction values until
calibration is complete.
**Impeller should be removed during calibration for best
results.
• Remove the impeller by pressing the edges to pop it out
(reinsert after calibration is complete).
To Calibrate:
• In Main Setup Menu, use
or
to highlight
“System”, then press
.
• Press
to highlight “Compass Cal”, then press
.
Follow the prompts on screen:
• Press
to start.
• Slowly spin the upright meter around three (3) full times.
• Each rotation should take approximately 10 seconds.
• When calibration is finished, the screen will read
“Cal Complete”.
• Press to exit to Main Menu.
To verify the digital compass’ accuracy, test it against a
compass; the Kestrel meter readings should be within
±5° of the reference compass or better. If readings appear
incorrect, simply run the calibration routine again.
Unit should be held vertically with the back facing the
direction being measured.
Calibration Error Messages
There are three error messages that the meter may
display during calibration. Press to exit the error
screen and run the calibration again.
• Magnetic Batteries:
The magnetic field of the Kestrel’s
batteries is interfering with calibration. Try opening
the battery door, rotate one or both batteries, and run
the calibration again. If
error persists, try using a
different brand of battery.
• Too Slow:
The unit was
spun too slowly during
calibration.
• Too Fast:
The unit was
spun too quickly during
calibration.
