3.
1. Set the 48.2 mm mounting metal pole for at least 50 cm into the ground,
keeping the pole as vertical as possible using a level. Hammer the metal
pole, keeping it protected with a piece of wood.

2. Insert the thinner pole into the grounded one and x it with the locking
ring at the desired height with the use of a 13 mm wrench.
3. Install the iMETOS station at 1.5 meter above the ground or depending
on the crop height. Fix the iMETOS with the two clamps on the verti-
cal pole using two 13mm-wrenches. Check the bubble level on the rain
gauge to ensure the iMETOS is installed verticality of the pole and align
the solar panel to face south (north in southern hemisphere).
SENSORS INSTALLATION:
• Temperature and relative humidity sensor should be mounted be-
tween 1.25 m and 2 m above the ground, depending on the crop. Leaf
wetness sensor can be tied to a branch of the plant or to the station
holder (next to the rain gauge), slightly inclined, with the lter paper
looking up. Mount it in a position that allows the sensor to pick up
early rain and to stay wet in the shade.
• Soil temperature sensor should be buried in the ground. The depth
will depend on the application. To monitor root growth and nitrogen
mineralization in vines or apples in early spring, it is best to install it
at 10 to 20 cm depth. If you want to assess the emergence of seeds,
install it at the sowing depth.
• If you ordered a wind speed sensor, install it on the top of the pole.
You will nd the three-cup wheel and the allen key to x it to the axis
of the sensor; if you also ordered the wind direction sensor, you will
nd a ”T” shaped holder with two clamps provided. The wind direc-
tion sensor should point to north and the wind speed sensor should
point towards south. Both sensors are sensitive to obstructions and
turbulence.
Note: 12 sensors can be connected directly to the iMETOS board; an
extended set of sensors (up to 600) can be connected via RadioNodes
or cable chain nodes. There is a connector on the top of the mother-
board for the radio access point. An alternative use of this connector is
to read up to two soil moisture prole probes or the snow depth sensor.
For detailed info about the installation of sensors refer to
metos.at/ime-
tos-3-3-manual or the extended manual.
START-UP THE iMETOS 3.3
On GPRS, UTMS, LTE (i.e. G2, G3, G4) networks a SIM card from a provid-
er is required. In CDMA network, you do not need a SIM card.
To insert the SIM card:
N

3. Lock the holder
by sliding the met-
al lock.
1. Slide the metal
part of the SIM card
holder to unlock it.
2. Place the SIM card into the hold-
er so the gold contacts on the SIM
face down on the board.
Your device is now up and running.The three LEDs on the motherboard
will turn on for an instant indication that the station has reset. After
this, the connection with FieldClimate will start and the LEDs will give
you information about the communication process (for more details see
Blinking code and SIM card sections on metos.at/imetos-3-3-manual). In
case you need further support, please contact [email protected].
iMETOS 3.3 is a durable and exible data logger for all weather con-
ditions, but if you remove it during the winter months and store in a
warehouse, please disconnect the battery to avoid discharge.

have data transfer service enabled.
1. Go to ng.eldclimate.com/
login and click the button
“+”.
2. Insert your personal
data & e-mail.
3. Check your e-mail and
click on the link to activate
the user account you created.

With the activation of licenses for site specic localized weather fore-
cast and plant disease models, it is possible to set these services for
each of your iMETOS stations. To activate them please contact your lo-
cal distributor or lic[email protected].
On Station settings page you can congure your iMETOS.
Station settings > Conguration: Under Time zone and location, you
need to provide the precise information, as weather forecast and other
services require it for accuracy. Under Logging and transfer settings, you
can dene how your iMETOS station logs and sends data. Please note
that the iMETOS station is delivered with the default factory settings
(as in the gure below). More options are available by clicking the “Ad-
vanced options” button.
Station settings > Sensors and nodes: You can dene a custom name for
your station and nodes connected to it. For convenient viewing of data,
you can also rename each sensor and customize its color in the graph.
Station settings > Warnings: You can add phone numbers and set
thresholds for each sensor, at which the warning SMS should be sent.
For further inquiries visit metos.at/eldclimate-manual.
MAINTAINING THE iMETOS
The iMETOS station should be checked periodically to ensure that
sensors are in optimal condition. Regular maintenance is necessary for
awless operation and durability.
At the beginning of the new season, check that the station is working
correctly; data must be transmitted at the set interval to FieldClimate.
Keep the solar panel and sensors clean and ensure correct rainfall
measurements by making sure the rain gauge is levelled (check the
bubble indicator), and not obstructed by leaves, insects or debris. Check
if leaf wetness sensor has the appropriate lter paper intact and posi-
tioned correctly (it should be replaced once, preferably twice a year).
When the solar panel of the iMETOS is exposed to the sun and gets
enough sunlight it should constantly recharge the battery of the system.
The lifespan of the battery is expected to be 5 to 6 years with sufcient
recharging from the solar panel. Deep discharge shortens its lifetime.
ADD YOUR iMETOS DEVICE TO YOUR ACCOUNT
Once registered, you can login to ng.FieldCli-
mate.com. To add your iMETOS device, click on
the icon in the top right corner User Menu >
Add/Remove station. It will ask you for a Station Serial number (SN)
and a station key. This information is found on the silver sticker (in
the gure) which came with your iMETOS station. Key 1 gives you full
(admin) access and enables you to change all the settings and set up
the iMETOS (e.g. data transfer interval, SMS warning, etc.); with Key 2
the user is not allowed to change the station parameters, but you can
access all the weather data.
THE iMETOS DASHBOARD, STATION DATA AND SETTINGS
The new Dashboard is designed with a widgeted structure, which al-
lows the user to customize access to the services of highest interest. On
the top right corner, Station List allows the user to choose among all
the iMETOS devices and select a single one.

The iMETOS will prevent this from happening and protect the battery
by limiting the data transfer to the safe level of charge. In doing so, data
is not lost and battery recovers faster.
UPDATING YOUR iMETOS
Every time the iMETOS 3.3 connects to FieldClimate, it checks for the
latest rmware version. If it nds a newer version, it automatically
downloads it and updates itself. iMETOS 3.3 can also be updated man-
ually via the USB connection.
