1. Product overview
Thank you for choosing the ULP Ultrasonic Anemometer
from Calypso Instruments. This ULP is the first model or
our generation II, representing an important technology
breakthrough condensing an extensive R+D investment:
· Both shape and firmware have been enhanced for an
improved rain performance,being this point key for static
applications such as weather stations.
· Mechanical design has been revamped making the unit
more robust and dependable.
· We feel very proud to release a unit that requires under
0,4 mA of power at 5V, sampling at 1Hz.
· Different output options available: RS485, UART/TTL and
MODBUS.
Applications for the ULP485 are the following:
Weather Stations | Drones
Temporary Scaffolding and construction | Infrastructures
and building | Cranes
Spraying | Irrigation | Fertilizing | Precision Agriculture
Smart Cities | Wild fires | Shooting | Scientific
2. Package content
The package contains the following:
· Ultrasonic ULP Wind Instrument plus 2 meter (6.5 ft)
cable for connection
· Serial number reference on the side of the packaging.
· A quick user guide on the back of the packaging and some
more useful information for the customer.
· · M4 headless screw (x6)

The ULP has been designed to avoid any mechanical
parts to maximize reliability and minimize maintenance.
The transducers communicate between themselves two
by two using ultrasonic range waves. Each pair of trans-
ductors calculates the signal delay and gets information
about both, wind direction and wind speed.

Noth mark position
Make sure the north mark
is perfectly aligned.

ULP is engineered to be a robust device with
minimal downtime. This new shape has been
designed for optimum water spillage which implies
lower probability of ice formation. Frost might
affect measurements if it blocks the wave path.
The input wires are protected by Transient Voltage
Suppression (TVS) diodes. Also, the instrument
body is built in Polyamide.
Every single unit is automatically calibrated on a
wind tunnel. A Q/C report for both module and
angle is generated and keptin our files. Standard
deviation is checked to warranty that each unit is
been calibrated to the hightest standards.
4. Conguration Options
The Ultrasonic ULP can be set up by using a special
App made by Calypso Instruments.
In order to use the APP you should download the
following configurator from our website at

8.2. Maintenance and repair
The Ultrasonic Ultra-Low-Power does not require great
maintenance thanks to the avoiding of the moving parts in
this new design.
Transducers must be kept clean and aligned. Impacts or
incorrect impulsive handling may lead to transducers
misalignment.
The space around the transducers must be empty and
clean. Dust, frost, water, etc... will make the unit stop
working.
8.3. Warranty
This Warranty covers the defects resulting from defective
parts, materials and manufacturing, if such defects are
revealed during the 24 months after the purchase date.
Warranty is void in case of non-following the instructions
of use, repair or maintenance without written authorisa-
tion.
This product is for leisure purposes exclusively. Any wron-
gful use given by the user will not incur in any responsibility
of Calypso Instruments. Therefore, any harm caused to
the Ultrasonic Portable Mini by a mistake will not be cove-
red by the guarantee. Using assembly elements different
from those delivered with the product will void the guaran-
tee.
Changes on transducers position/alignment will avoid any
warranty.

5. General information
5.1. General recommendations
The Ultrasonic Ultra-Low-Power has been calibrated with
accuracy, following the same calibration standards for
each unit.
Regarding mounting the unit, as we have described before
, the mast head has to be prepared for the mechanical
installation. Align the North mark of the Ultrasonic Porta-
ble Mini, in order to have it pointed towards the bow. Make
sure to install the sensor in a location free from wind
perturbation, usually on the mast head. Other important
aspects:
- Do not attempt to access the transducers area with your
fingers;
- Do not attempt any modification to the unit;
- Never paint any part of the unit or alter its surface in any
way.
- NOT allow to be submerged fully or partially in water.
If you have any questions or doubts, please contact us
directly.
