The configuration is carried out by connecting the USB output of the data logger to a PC and by
using the supplied application software Meteo Studio. The configuration of the data logger is
protected by a password that prevents unauthorized changes.
M
EMORY
The internal memory is managed as a circular buffer: when the memory is full, the new data
overwrite the older ones. Data are also stored hourly in an SD memory card. The use of the
memory card allows to extend the instrument storage capacity, so not to lose data when the in-
ternal memory is full. The data logger operates with normally commercially available SD cards.
The values stored by the instrument can be transferred to the PC by using the Meteo Studio
software. As an alternative, it is possible to remove the SD card and introduce it in a card reader
connected to the PC.
GSM/UMTS C
ONNECTION
An optional GSM/UMTS module allows sending logged data via e-mail, FTP and to Delta
OHM Cloud, and alarm SMS once the settled measuring thresholds have been exceeded or
when the battery reaches the minimum charge level.
Three versions of the module are available: HD5320.E (for use in Europe), HD5320.U (for
use in U.S.A. and Canada) and HD5320.J (for use in Japan).
The data logger is designed for the periodical transmission of the stored measurements to data
collection weather sites "www.wunderground.com" and "www.pwsweather.com".
The GSM/UMTS module allows the automatic update of the data logger clock.
Once the module is installed, Internet connection to the data logger can be performed from a
remote server through a direct TCP/IP connection.

UPPLY
Data logger power supply: 17…26 Vdc. The system can be powered at 100…240 Vac by mains
(by using the optional HD32MT.SWD external AC/DC power supply unit) or by a solar panel,
allowing installation in sites with no power supply. In both cases, a battery charger is installed
inside the case. In order to reduce energy consumption, sensors can be supplied by power
outputs that can be activated only when measurements have to be performed (except for par-
ticular sensors requiring continuous power supply).
The 12 V rechargeable backup battery inside the case prevents the loss of recordings in case of
no external power supply. An internal lithium battery allows to maintain date and time even
when the backup battery inside the case is not connected.

The four-line dot matrix LCD display allows to view the values acquired by the data logger and
the operation status, without connection to a PC.

ROTECTIONS
The data logger is supplied already mounted inside a hot-pressed, fiber glass reinforced polyester
case. The case is equipped with key lock and a power-coated anodized aluminum protection shield
against solar radiation. An optional sensor (HD32MT.ALM), connectable to a dedicated input of
the data logger, is able to detect the opening of the case door and to provide an alarm signal. The
case has a IP 66 protection degree and is in compliance with UL/CSA/AS.

ONNECTION TO A
PC
AND APPLICATION SOFTWARE
The connection to a PC through the USB port of the data logger does not require the installation of
any USB driver: when connecting the instrument to a PC, the Windows® operating system auto-
matically recognizes the instrument as an HID device (Human Interface Device) and uses the driv-
ers already present in the operating system.
