4 Introduction
Congratulations!
on your purchase of the pocket weather station Windwatch PRO
This operation manual provides detailed information about the operating mode of the
Windwatch PRO instrument. By using your new, multi function instrument which is equipped
with four high precision sensors, you are able to measure wind, air pressure, altitude,
temperature and relative air humidity. Moreover, your pocket weather station provides the
feature of Windchill and dew point calculation, as well as very useful functions for timer, alarm
and alarm clock. The purpose of this operating manual is to make yourself familiar with the easy
handling of the instrument and to stimulate at the same time the comprehension for
meteorological correlation. Some more comments related to meteorology-physical conditions
are specifically addressed to the ambitious user.
Summary of Functions
The Windwatch PRO provides the following
six main function screens
, shown with
corresponding symbols that are visible in the upper part of the display:

Backlight
Long-press the MENU key for 2 seconds to activate the display backlight. The backlight
consumes higher-than-normal battery power; therefore it is recommended that it only be used
when the display could otherwise not be read. When the battery condition is weak, the backlight
function is automatically disabled and a “No Li” message is briefly shown in the display upon the
next menu change. All other functions of the instrument remain operative until the battery is
completely exhausted.

Set-Mode for the Main Display Screen
4
SEC
A long press (4 seconds) of the MENU key brings up the
set-mode
for the current main function
shown on the upper line of the display. With the WWP in set-mode, the value to be set will be
flashing and can be adjusted with the UP and DOWN keys.
Example: When the WWP is in the Altimeter screen, pressing the MENU key for 4 seconds
allows the altitude to be adjusted.
Use a short press of the MENU key to escape set-mode – or, if no key is pressed for 7 seconds,
set-mode is automatically escaped.
Set-Mode for Secondary Functions
4
SEC
A long press (4 seconds) of the SUB key gives access to the set-mode for that secondary
function (the values on middle and lower lines of the display). When in set-mode, the value to be
set will flash and can be adjusted with the
and T keys.
S
Example: When the WWP is in the Altimeter screen, pressing the SUB key for 4 seconds allows
the adjustment of the Relative Altimeter.
A short press of the SUB key will accept the value that is flashing and will cause the next value
that can be adjusted (if any) to flash. If there is no further value to be adjusted, a subsequent
press of the SUB key will escape set-mode – or, if no key is pressed for 7 seconds, set-mode is
automatically escaped.
Select Measuring Units
A short press of the S or T key in any display screen will change the measuring units. If there
are more than two possibilities, subsequent shot presses will scroll through the choices.
Example: In the Altimeter screen, a short press of either arrow key will change the display from
meters (m) to feet (ft).
Start - Stop - Reset
When the WWP is in the Stopwatch screen, the left key is used to start and stop the stopwatch.
A short press of the right key marks the interval time, whereas a long press resets the
stopwatch to zero.
A long press of the RES key resets the primary displayed value of the current function shown on
the display. Example: in the Altimeter screen, the reference altimeter can be reset to zero with a
long press of the RES key.

Barometer
By tracking air pressure trends at a given location it is possible to make predictions
about approaching weather conditions. The barograph on the WWP Barometer main
screen represents the air pressure progression over the past 3, 6, 12 or 24 hours (user
selectable where each bar represents 1/12
left to right so that the value on the left is the oldest and the value on the right is the most
recent. Each segment in a bar corresponds to a pressure change of 2 hPa. The WWP
measures and updates the digital air pressure display every 7.5 minutes.
If the diagram is ascending from left to right, it signifies an increasing barometric
pressure trend, which is generally associated with dry weather conditions, sunshine and
blue skies. Conversely, if the graph is decreasing from left to right it indicates decreasing
barometric pressure, generally associated with a warm or cold front. For alpinists, hikers,
pilots and other outdoor sportsmen this is a warning sign for the possibility of bad
weather and the need to watch for worsening conditions. These front systems very often
produce a change in the weather, combined with low clouds and the possibility of
persistent rains or snow.
th
of the period selected). The graph runs from
Barometer Pressure Display QNH / QFE
Because air pressure decreases with altitude, it is necessary to relate air pressure at a
given elevation to the air pressure at sea level. In meteorology this value is referred to as
QNH. The average pressure at sea level during one year over medium latitude is
1013.25 hPa; this was set as standard pressure by the ICAO for the flying sector in
1928.
To measure air pressure at an altitude other than sea level, you must enter the altitude
of your current position into the barometer. In the WWP this height value is entered in
the set-mode for the Barometer screen. This also means that if the instrument is moved
to a location with a different elevation, the new reference elevation must be entered. If
the altitude of the WWP changes by more than 50 meters within a short period of time,
the barometric graph is automatically cleared and restarted.
If the reference altitude is set to zero, the displayed pressure is the actual air pressure at
that elevation and is referred to as QFE (Absolute Pressure).
