Introduction
Background information
The GEOS N°11 is a high performance instrument used by professionals,
the culmination of our 25 years of experience in the development and
manufacturing of measuring devices. It is solely built with industrialquality components and uses Swiss-made barometric pressure, wind
speed, humidity, and temperature sensors.
The instrument is put together with great care in our Swiss
manufacturing facility, where sensor accuracy is controlled using our
quality-certified laboratory equipment.
The GEOS N°11 is specially designed for intensive use in extremely
harsh conditions. Yet, in order to maintain its aspect and accuracy, we
recommend that you treat it with care and that you read this Manual
carefully.
WARNING
This instrument is designed as an aid to users who are in an open air
environment, but IT CANNOT replace advice and warnings from the
local weather station. This means that you should regularly check and
compare the measurements provided by your instrument with the
information put out by the weather station.
Open-air climatic conditions can sometimes change quite dramatically
and this can happen very quickly indeed. Sunny weather can, for
example, change to thunderstorm conditions in the space of half an hour
and sometimes less. You should therefore always follow basic safety
rules whenever you undertake open air activity.
Under no circumstances shall JDC ELECTRONIC SA be held liable for
any consequence, be it direct or indirect, and for any damage that may
occur as a result of using this instrument.

Display principle with regard to functions (measuring modes)
Each measuring mode occupies a very particular space on the screen.
Measuring modes are always displayed following the same principles, i.e.:
- 1 standard screen containing all the basic measuring modes.
- 1 screen per special mode, when activated.
- 1 'special menu' used to enable/disable the special modes, view
memories and carry out some adjustments.
Distribution of basic modes over the standard screen
Each block (with the exception of the large one), accommodates several
measuring modes; however, only one mode may be displayed at the
same time per block. The basic measuring modes are displayed on the
standard screen as follows:
upper block: average and maximum wind speed
large block : instantaneous wind speed
middle block: all the temperature and humidity measuring modes,
including dew point
lower block: digital compass and all the functions relating to
pressure, including altitude, flight level, and height
compass block: analogue compass (1 mark located under the bargraph
indicates the heading)
The SEL ( ) button is used to select a block (the block flashes when
selected). The selection time (flashing) is 5 seconds. Each time the

button is pressed briefly, the next block is selected in the following order:
upper, large, middle, lower, upper, etc. If one (or several) special mode
has (have) been activated, the selection will take place as follows: upper,
large, middle, lower, special mode screen, upper, etc.
The MOD ( ) button is used to modify the display of a block (it scrolls
down the various modes of the block), and will only work if the block is
selected.
Remark: The last mode displayed on a block becomes the default
mode for this block, which means that if the instrument is switched
off than turned back on, the standard screen configuration will be
the same as the configuration displayed before it was switched off.
Starting up the Instrument
First Use (out of factory)
When fresh out of the production line, the instrument is supplied in a
storage state, i.e. with all the sensors disabled, including the internal
clock. This state allows the storage of the instrument for a long period
of time without running the battery down.
Press and keep down the

switch to an even greater scrolling speed, release then keep the

006 = 2006) cannot be set individually, but changes automatically when
passing from December 31st to January 1st. Once the date is set, keep the
button down to confirm your settings.
You are now about to set the time. With the button

Remark: Setting the date and time may also be carried out at a later
stage. Please refer to Section on ‘Special Modes’; ‘Date and Time’.
Instantaneous State
(The instrument remains turned on for only 5 seconds)
This state allows you to see the current measured values at a glance,
while saving the battery.
When the instrument is off, pressing the

Switching the Instrument off
In order to manually turn off the instrument, keep any of the buttons
down for 3 seconds; the stop screen is displayed and a countdown takes
place on the large block: 3, 2, 1, 0, followed by the deactivation of the
instrument. The middle block indicates the time before the automatic stop

Basic Measuring Mode
(Standard Screen)
Reminder: All the basic modes that are described hereafter are
available on the same screen ( standard screen), only the special
modes avail of a screen per mode (see relevant section).
The last measuring mode displayed on a block becomes the default
mode for this block; when you turn your instrument off and back on
again (instantaneous and normal states), the configuration of your
standard screen will be the same as that displayed when the instrument
was turned off.
General Use of Buttons
SELection Button: a brief push of the button selects a block of the
standard screen or a special screen, the block flashes when it is
selected (the selection/flashing time is 5 seconds). When settings
are entered or when looking at data, pressing it briefly makes it
possible to change the direction of the adjustment. As a rule,
pressing the button for 2 seconds will bring the standard screen
back up, allow to terminate a calibration, or exit the special menu.
By pressing it for a long time (3 seconds) in a flashing state it is
possible to access the settings of a number of values. If the
standard screen is normal (not flashing), pressing the button for a
long time will turn off the instrument.
LUMminosity Button: a brief push of the button switches on the
backlighting for 5 seconds, or turns it off if it is already on.
Pressing the button for 1 second turns on the backlighting for a
duration of 20 seconds. Activating a button when the backlighting
is on, keeps it on for another 20 seconds, this in order to stop it
from switching off while performing an adjustment for instance.
Pressing the button for a long time turns off the instrument.
MODification Button: a brief push of the button changes the
display of the selected block and gives access to the memories.
Pressing the button for a long time makes it possible to change the
unit of measurement of the selected block and reset certain values.
Pressing the button for a long time turns off the instrument.

Wind speed
Measuring modes
Instantaneous wind speed Maximum wind speed Average wind speed
The measuring modes for the maximum and average wind speeds are
displayed on the upper block, while the instantaneous wind speed is
displayed on the large block. In order to access the measuring mode for
the maximum reached or average wind speed, select (with the help of the
button) the upper block (it flashes), then use the button to modify
the block display and switch from one measuring mode to another.
Resetting the maximum wind speed to zero
Select the upper block and display the measuring mode for the maximum
wind speed (it flashes), then press the
button for 2 seconds.
Selecting the unit of measurement
The instrument features 6 units of measurement in relation to wind
speed: km/h (kilometres per hour), mph (miles per hour), knots, m/s
(metres per second), fps (feet per second) and Beaufort (Beaufort scale).
To change the unit of measurement, select the large block (it flashes),
then keep the
button to confirm your choice.
