You now own a sophisticated, precise,
and comprehensive weather monitor. Please
study the manual to understand all of the unit’s
features and to maximize its benefits.
Getting Started
Open your WindMate
shown on the right. If using a tripod,
open it to a 90
o
angle as shown ab ove
to access the tripod fitt ing a t the b ott om
of the unit.
Press and hold Mode Key to turn on.
Press and hold Mode for 3-4 secs. to
turn off. You can turn off the unit in any
function. If the unit is idle f or 5 m inutes,

When the unit is turned on for the first time, the
default mode is Time. Each time the unit is
reactivated, it returns to the last function used.
Press the Mode Key to move to other functions.
For Backlight, press SET/EL.

Choosing Measurement Units
Pressing and holding the Set/EL Key at any
mode, (except time, compass and humidity),
chooses your preferred measurement unit.
Press the View Key to select, then pres s Set/EL
to save and exit Units Setting. Below is the
sequence of measurement units for each mode.

Bar Graph Display
For best results with any bar graph display, set
the low and high limits of the instrument
reflect the range of actual conditions the unit will
to
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 W M-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 Histor y display option. Your unit
is preset for 1-hr increments and 48-hr bar
graph. (See Customizing your WindMate
to change the storage interval.) To change the
display option from the normal view press the
View Key. The diagram below will s how you the
sequence.
The current view shown in the History is the
recorded data of the prev ious hour. To view the
recorded data histor y previous 2 hours, 3 hours
and etc. press the Set/EL Key. The recorded
data will be displayed in nu mer ical format and at
the same time will be indicated in the graph.

Time
The Time mode will display the following
information: com plete date, weekday and 12-24
HR format option.
To set the time, press and hold the Set/EL Key
for 3 sec. To adjus t the c urr ent s e tti ng, pr ess th e
View Key. To go to the next option, press the
Mode Key. To exit and save the setting, press
the Set/EL Key.
Wind Speed
In the wind speed mode, you can take real t ime
wind speed measurements. Press View to
display Max-Avg, press View again to display
bar graph history. Press Set/EL to view each
increment. Press Mode to go to next function.
When taking wind measurements by hand, be
sure to keep the unit at an arm ’s length f rom t he
body with the display facing to wards 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 re adings 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 m id-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 vert icall y)
The compass feature can compute the cross
and head wind. Align the unit to the course
direction, press and hold the View Key to m ark
the course direction. Then point the unit direct ly
into the wind to mark wind direction, press and
the View key. The unit will display cross
hold
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 ar e on the eart h,
the angle of declination will be different—
in some locations, the geographic and
magnetic poles are aligne d so declination
is minimal, but from other spots, the angle
between the two poles is l arge. 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 sc reen. Press Set/EL and
the display shows “END.” If the display shows
“ERR” redo the calibration.

Choose the function you wish. Press View to
display Min/Max. Press View to display his tory
bar graph. Press Set/EL to view each
increment. Press View to return to normal
function or press Mode to go to the next.
**DeltaT is the difference between wet & dry
bulb temperature, used in agricult ur al spr a ying.
***Density Altitude is pressure altitude adjusted
for air temp and humidity, used for aircraft,
formulating race car f uel mix, & very long-range
shooting.
Comfort Index
Accuweather.com ®Comfort Index™ is t he 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 ho ld 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
