Bar Graph Display
For best results with any bar graph display, set
the low and high limits of the instrument to
reflect the range of actual conditions the unit will
experience. In all modes except Time and
Compass, press and hold the Set/EL key until
the current unit of measure is flashing. Press
the Mode key to see the “Low Limit” of measure
the instrument will graph. Press the View key to
increase the value of the “Low Limit.” Holding
down the View key will cause the increase to
take place much faster. If you go past the value
you desire, continue to increase the value until it
scrolls around back to the number you need.
When you have reached the value you need,
press the Mode key and you will then be able to
set the “High Limit” that the instrument will graph
in exactly the same way. When you have
reached the value you need, press the Mode
key again and screen will go back to the current
unit of measure flashing. Press the Set/EL key
to save and exit. Changing the “Low Limit” and
“High Limit” values of the WM-350 only changes
the representation of the history graph. It does
not change any of the previously recorded data
or have any impact on the data yet to be
recorded.
History and Min/Max Feature
All modes, except Time and Compass, have a
Min-Max and a History display option. Your unit
is preset for 1-hr increments and 48-hr bar
graph. (See Customizing your WindMate®350
to change the storage interval.) To change the
display option from the normal view press the

When taking wind measurements by hand, be
sure to keep the unit at an arm’s length from the
body with the display facing towards you, so the
wind enters the impeller through the rear. Use
the wind vane to orient the meter so you are on
the wind’s axis. This will give you the most
accurate measurement.
To get precise readings on a given vector, use
our optional wind tunnel with the unit mounted
on a tripod.
CAUTION: The WindMate®is very accurate at
low and mid-range air speeds. Consistent uses
at very high speeds, such as from a car, will
damage the impeller’s bearing and reduce
accuracy. See below for impeller replacement.
Compass (hold, read, set vertically)
The compass feature can compute the cross
and head wind. Align the unit to the course
direction, press and hold the View Key to mark
the course direction. Then point the unit directly
into the wind to mark wind direction, press and
hold the View key. The unit will display cross
wind. Press View to display head wind. The
head wind may indicate a minus(-) or plus(+).
Minus will indicate the wind is coming from the
back. Plus will indicate wind coming from the
front. Press Mode to return to compass.
Compass Calibration for Declination &
Deviation
Compass Declination
Declination/Variation is the difference
between magnetic N and true N.
Depending on where you are on the earth,
the angle of declination will be different—
in some locations, the geographic and
magnetic poles are aligned so declination
is minimal, but from other spots, the angle
between the two poles is large. To adjust
your compass,
get declination information from a GPS or
www.ngdc.noaa.gov/geomagmodels/struts/calc
Declination .
Go to compass mode and hold Set/EL Key till
display shows HOLD TO SET. Use the View
Key to choose E or W. Then press Mode and
degrees will blink. Use View to change the
degrees. Press Set/El to lock in values.
Compass Deviation (only necessary if the
compass is near ferrous metals)
In compass mode press and hold Set/EL until
you see HOLD TO SET. You will see the
declination setting. Press Mode twice. Screen
will say Calibrate Compass? YES. Press Mode.
(If you do not need to calibrate, press View for
NO. Press Set/EL.) Hold the unit and turn
around slowly twice, 15 sec per each ¼ turn.
When calibration is complete, you will see 11
dots at the top of the screen. Press Set/EL and
the display shows “END.” If the display shows
“ERR” redo the calibration.

shooting.
Comfort Index
Accuweather.com®Comfort Index™ is the effect
of temp, wind speed, relative humidity & sun
intensity on the human body. You can adjust
the formula based on sun intensity. The solar
factor has range from 0 to 3.0. Full sun = 3.0.
Heavy clouds = 0. The unit is preset for 1.5,
medium sun intensity.
To change, press and hold the Set/EL Key and
press the Mode Key again to go into solar
factor. Press View to select the desired value,
then press the Set/EL Key to confirm and exit
the setting mode.
Barometer and Altimeter
Understanding Barometric Pressure
High or low air pressure caused by weather, and
air pressure caused by elevation affect the
barometer’s reading. No matter what the
weather is doing, air pressure decreases with
height. Actual or STATION pressure is the true

air pressure at a fixed point. However, the
weather service gives us the barometric
pressure reading, which adjusts for elevation.
Example: In Denver, an average barometer
reading will be 29.90, however, the STATION
(uncorrected) pressure might be 26.10 because
of Denver’s elevation. The barometric pressure
reading gives us a frame of reference within
parameters we understand.
Barometric Pressure
The barometric pressure should be calibrated for
first time use, after battery replacement, or if the
altitude of your position changes.
Calibrate the weather
forecast icon: press and
hold the Set/EL Key for
3 sec while in the
normal Barometer mode or Min-Max mode.
Select the preferred measurement unit by
pressing the View Key. Press ModeKey and
select the weather icon most appropriate for
your current weather condition, using the View
Key. Note: If you recalibrate because of an
altitude change, you don’t need to repeat this
part of the setup.
To calibrate the barometric pressure, you can
either: a) enter your correct altitude in the
Altitude function (See Altitude), or b) enter the
correct barometric pressure for your location, if
available.** In Barometer Mode, press and hold
Set/EL Key for 3 sec. Scroll till you see the
pressure displayed. Press Mode Key. Enter your
current barometric pressure by pressing the
View Key. Press Mode Key to go to the next
digit. Press the Set/EL Key to save and exit the
Calibration settings.
** You can use the barometer reading from your
local weather service. Weather cells can be
small and pressure different within a local area,
but for initial setup, the weather service pressure
figure should be fine.
The instrument will display air pressure either as
uncorrected STATION pressure or
BAROMETER for barometric pressure
(corrected for elevation). The BAROMETER
reading is what most of us are used to.
Using the Barometer
In Barometer mode, press View to display
Min/Max. Press View again to show pressure
and bar graph. If you want to review pressure
history, press Set/EL to review each past
increment. Press View again to see 6-12hr
weather forecast. Press View again to see the
current BAROMETER reading. Press Mode to
go to the next function.
Storm Warning Alarm
If there is a 6-millibar change in air
pressure over a 3-hr period, the
Storm Alarm will sound “BEEP
BEEP BEEP” every 15 minutes and an icon will
blink on the screen. This will also occur if you
experience dramatic changes in elevation. See
Customizing your WindMate®350 to
deactivate this feature.
Altitude (Altimeter)
The Altimeter must be calibrated for first time
use and after a battery replacement. If you stay
in one location, additional calibration is not
required. If you change locations (hiking,
climbing) and use the altimeter, you must re-
calibrate at known benchmarks to maintain
accuracy. The altimeter readings are also
affected by any weather-related air pressure
changes.**
To calibrate the Altimeter press and hold the
Set/EL Key for 3 sec while in normal Altimeter
mode or Min-Max mode. Select the preferred
unit of measurement by pressing the View Key
and then press the Mode Key to confirm. Enter
the current altitude by pressing the View Key
then press Mode Key to go to the next digit.
Press Set/EL to save and exit the Calibration
settings. This calibration requires you to enter a
known altitude for your location.
** Understanding the Altimeter
The WM-350 altimeter functions via barometric
pressure changes, unlike a GPS, which reads the
GEOMETRIC altitude, relative to a sea-level baseline
that is defined in the WGS84 coordinate system. GPS
altitude is unaffected by atmospheric conditions.
Airplane altimeters use the barometric measurement
system, but are constantly updated in flight. To
compensate for weather changes, your altimeter must
be calibrated using a known altitude. If you are
climbing and want accurate data, you may need to
re-calibrate frequently at known elevations.
Using the Altimeter
In Altimeter mode, press View to display
Min/Max. Press View again to show Altitude bar
graph. To review history, press Set/EL to
review each increment. Press View to return to
normal Altimeter mode or press Mode to go to
the next function.
