Pessl Instruments nMETOS FROST User manual

Thank you for choosing a nMETOS FROST station for monitoring your ag-
rometeorological conditions towards the FieldClimate decisions support
system. The nMETOS FROST has been designed to monitor data with a
set of sensors oriented for frost prediction and alarms. Like other pro-
ducts of the METOS® family, it measures and sends data to the Field-
Climate platform using the NB-IoT service. The users have free access to
data through web,mobile applications and decision support systems.Ad-
ditional services (like weather forecasts) are available with a subscripti-
on fee.Web API is available for interface with other custom applications.
nMETOS FROST system is used for:
• Frost prediction
• Frost protection activities planning
• Frost alarm notications
We encourage clients to use an additional 3 month weather forecast
licence for predicting near future conditions and for planning services.
The product uses two standard type D batteries which the client can
source locally in any shop and are not included in the delivery package.

ACTIVATE YOUR WEATHER FORECAST
With the activation of subscription for the 3-months localised weather
forecast, real-time measured data from your station‘s wet and dry
bulb temperature sensors are coupled with an accurate prediction of
temperature trends over the next 48 hours. This allows you to know
your current orchard and/or eld conditions, a site-specic forecast for
the key frost conditions and to track the historical trends. This graph is
part of the Extreme Weather Monitoring page (see gure below).
To activate the Weather Forecast, contact your local distributor or
[e-mail].
SET YOUR REAL-TIME FROST ALERTS
From site-specic sensors, the frost module provides the
measurements of wet and dry bulb temperature. When a frost event is
close to happening an alert is sent by text, sound and email. This way
growers know the exact moment in which crops are at risk and this
will help save them money. Furthermore, it can determine if your frost
mitigation tools are having the desired effect or need to be adjusted
for efciency.
To set new alerts go to Settings > Notications.

MAINTAINING THE nMETOS FROST
The frost module 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 and, in particular, that the plastic bottle is full of water; if the
bottle is empty the wet bulb temperature will not be accurate.

START-UP THE nMETOS FROST
By default, the nMETOS FROST station comes without a battery and
based on your order, it can come with or without a SIM card.
To start up the nMETOS FROST, it requires opening the housing,
inserting the SIM card and in special cases checking the settings via
the USB cable connected to the PC with the PI-Terminal/TeraTerm
application and connecting the battery.
To use the NB-IoT or CAT-M1 connectivity you need a SIM card which
is provisioned for the NB-IoT/Cat-M1 network from the network
provider and sufcient signal from the radio tower.
INSERT THE SIM CARD AND CONNECT THE BATTERY
1. Open the housing by unscrewing the 4 screws on the top.
2. Remove the board cover.
3. Slightly push the cover of the SIM card holder (circled red on the
picture below) rightward to unlock it.
4. Insert the SIM card correctly (contacts should be on the bottom side
and the marking corner in the upper right position).
5. Close the cover and push it gently leftwards so the cover gets locked.
6. Plug the battery cable into the SCAP connector on the PCB.
7. Close the cover to its nal position and tighten the screw.

INSTALLING YOUR nMETOS FROST
The nMETOS FROST comes with clamps to
install it on a pole. At the side of the unit
is a metal mounting frame. Push the long
clamp screws through the holes on the
metal mounting frame. Loosen the clamps
so they come around the pole. Tighten
the small nut to x the device in place on
the pole. Remember to ll the bottle with
water before the frost season starts.
