Getting Started
Open your POCKETWIND IV to 180
shown. If using a tripod, open your
o
POCKETWIND IV to a 90 angle as shown
above to access the tripod fitting.
To turn the unit on or off, press and hold
Mode key for about 3 sec. You can turn off
the unit at any mode. If the unit is idle for 5
minutes, it will auto shut down to preserve
battery life.
When taking wind measurements by hand,
make sure to keep the POCKETWIND IV at
arm's length from the body with the display facing
towards you so the wind will enter the wind impeller
through the rear. Use the wind vane to orient the wind
meter so you are on the wind's axis. This will give
you the most accurate measurement.
CAUTION: The POCKETWIND IV is very accurate at
low and mid-range air speeds. Consistent use at very
high speeds, such as from a fast-moving car, will
damage the impeller's bearing and reduce its
accuracy.
Using the wind meter functions
When the unit is turned on for the first time, the default
mode is wind speed. Going to other modes or features
is simply done by pressing the Mode button.
Pressing Units key at any mode, except Compass and
Humidity, changes the unit to your preferred
measurement unit. Sequence of units of measurement
is shown below.

Compass Calibration
If necessary, to correct for the presence of
ferrous metals, the compass can be
calibrated. Go to compass mode press
and hold SET/EL key till display shows
"COMPASS CAL" (blinking). Turn the unit
in a vertical position as shown. Turn the
unit around twice, 15 sec per turn, as
shown. After completing the 2 turns press
SET/EL key to confirm calibration. If the
display shows "END" the calibration is
successful. If the display shows "ERR"
redo the calibration process.
Digital Wind Direction
Point the POCKETWIND IV directly into the wind and
select Compass mode. The edge of the wind vane will
point directly towards you. Wind direction is displayed
digitally and in compass points.
The compass feature can also compute the cross and
head/tail wind. Point the meter in the direction of
travel or target and get a steady compass reading.
Press and hold Units key until MARK stops blinking.
Release Units key and point the meter into the wind
until you have a steady compass reading. Press and
hold Units key until MARK stops blinking. The meter
will display cross wind and to view head wind press
the Units Key. The computed cross and head/tail
wind may indicate a minus (–) sign. The minus (–)
sign will indicate the wind is coming from the back,
while no sign will indicate that the wind is coming from
the front. To exit, press Mode.
Setting the Comfort Index™
Accuweather.com® Comfort Index™ is the effect of
temperature, relative humidity, wind speed & sun
intensity on the human body. You can adjust the
formula based on sun intensity. The solar factor has a
range of 0 to 3.0 with a default setting of 1.5 (medium
sun intensity). Example: Full sun = 3.0; Heavy clouds
= 0. To change, press and hold SET/EL key. Press
Units key to adjust the current value of the solar
factor and press SET/EL to confirm and exit the
setting mode.
Replacing the Battery
The unit uses a CR2032 Lithium battery. Turn the unit
to the back. Use a coin to turn battery cover as
indicated by the arrow. Insert the battery with the
printed side facing you and close the battery door.
