Product Description

HD2013-DB is a data logger that has been specifically developed to capture
and store rainfall trends. It works with a long life lithium battery that provides,
together with the large memory, remarkable recording capacity without user
intervention. For user convenience, the supplied lithium battery, when exhausted,
can be also replaced by three alkaline batteries (not supplied with instrument).
The backlit display shows in real time the rain quantity during various time
intervals.
The instrument is perfectly waterproof thanks to the use of reed relays, instead
of the common push-buttons. The reed relays are operated through a magnet,
attached to the end of an aluminium handle tied to the case. When not in use,
the magnet is placed back into its holder.
The software HD32MTLogger supplied with the instrument allows setting of
the parameters of the instrument, the real time display of the values captured
by the data logger, the download to a PC and the process of the stored data.
The connection to the PC is made via the M12 8-pole RS232C serial connector
placed at the bottom of the instrument.
HD2013-DB can be connected to the most popular types of rain gauges with
normally closed (NC) or normally open (NO) output contact.
The display auto power-off feature allows to prolong the battery life. A front LED
lets you check the operating status of the instrument when the display is off.
The LED changes color when the rain gauge contact switches, thus allowing to
verify that the rain gauge tipping bucket returns correctly in the stable position
after emptying.

Installation and connections
The housing of the data logger has IP 67 protection degree and can be wall
mounted or, in the case of installations with the rain gauge off the ground, fi xed
to the rain gauge support by means of the HD2003.77/40 clamping. Diameter
of the support: 40 mm.

Two connectors are placed at the bottom of the housing: one 4-pole M12
male connector for the connection to the rain gauge and one 8-pole M12 male
connector for the connection to the PC. The arrangement of the two connectors
is also clearly indicated on the front mask of the data logger.

Over-voltage protection: the data loggers supplied with the mast clamping
already mounted on the back of the housing are provided with internal overvoltage
protection devices, connected to the clamping. For the correct operation
of the protection devices, the mast on which the clamping is fixed, must be
connected to ground.
Keyboard
The two function keys that allow to control the instrument are formed by two
reed contacts, operable from outside by means of a magnet supplied with the
instrument.
Two red areas are indicated on the front of the instrument, corresponding to the
word “ENTER” and to the symbols p and q: on these areas will be placed the
magnet to operate the instrument. Keeping the magnet on the red area for a few
instants and then moving it away is equivalent to press a button. For simplicity,
in the description of the instrument that follows, this operation will be called:
“press the ENTER button”, “press the p/q button”.
After use, the magnet with its support should be placed back into its holder.
Operation
The data logger counts and stores the number of emptying of the rain gauge
tipping bucket. Each emptying of the bucket corresponds to a quantity of rain
equal to the resolution of the rain gauge. The resolution can be set from 0.050 to
1.599 mm of rain by using the HD32MTLogger software. The rain gauge contact
can be both NC and NO type (it is not necessary to set the contact type, the data
logger automatically works with both types of contact).
Status indicator: the LED indicator of the data logger indicates the status of
the contact of the rain gauge. The LED blinks red if the contact is open, and
green if the contact is closed. Therefore, the LED color allows to highlight
the emptying of the bucket and check that the bucket returns in the stable
position after emptying.
Display: the display is backlit; to minimize the battery consumption, the display
is switched off if no operation is peformed on the data logger for 2 minutes.
However, the data logger is still working even when the display is off, and its
activity is signaled by the flashing status indicator LED. In order to turn the
display on, press any of the two buttons. When the display is on, the following
screens are displayed sequentially:
• quantity of rain in mm in the last hour and the last 4 hours;
• quantity of rain in mm in the last 24 and 48 hours;
• quantity of rain in mm in the last 72 and 96 hours;
• quantity of rain in mm from the last counter reset (partial rainfall); if the correction
table is enabled, both the uncompensated and the compensated values
are displayed (Note 1);
• date/time and battery voltage;
• user code and serial number of the data logger.
Note 1: if the rain gauge connected to the data logger has a measurement
correction table as a function of the rainfall rate, the partial rainfall compensated

values can also be displayed by storing the correction in the data logger. By
default, the correction is disabled. The correction can be enabled by using the
HD32MTLogger software. The correction is not applied to the values of quantity of
rain in 1h, 4h, 24h, 48h, 72h and 96h.
The values of the quantity of the rain are shown on the display with 0.1 mm
resolution. The internal resolution of the data logger is 0.001 mm and the
thousandth values are visible by downloading the data to the PC with the
HD32MTLogger software.
The data logger indicates “over-range” if the rain quantity in 1h, 4h, 24h, 48h,
72h, 96h exceeds 1000 mm.
The counter of partial rainfall is limited only by the memory capacity (32.255
samples). The memory is managed cyclically: the new sample overwrite the
oldest.
Reset of the partial rainfall counter: the reset of the partial rainfall value can
be performed by using the HD32MTLogger software or directly by using the data
logger keyboard according to the following procedure:
1. turn the display on, if turned off, by pressing any of the two buttons on the
data logger;
2. wait until the display shows the message “Use magnet to enter MENU”;
3. press the p/q button by using the magnet; “RESET INCR. COUNT” indication
appears;
4. select “YES” by pressing ENTER button; the data logger automatically exits
MENU.
To exit MENU without resetting the counter, when “RESET INCR. COUNT”
indication appears select “NO” by pressing the p/q button, then select ENTER
button to exit.
Date/time, user code, resolution, correction table and language of the data
logger can be set by using the HD32MTLogger software (see the instructions
of the software).
Connection to PC
The data logger is provided with an RS232 serial port with 8-pole M12 connector
located at the bottom of the instrument. For the connection to the PC use:
• the HD2110RS cable for the connection to a RS232 port of the PC;
• the CP25 cable for the connection to a USB port of the PC; to use the CP25
cable, the related USB drivers must be installed in the PC.
With the HD32MTLogger software, for Windows® operating systems, it is
possible to set the parameters and the language of the instrument, view in real
time the values captured by the data logger, download to the PC and process
the stored data.
When the data logger is connected with the HD32MTLogger software, the backlit
display is always on. To prolong the battery life, it is recommended to maintain
the connection only for the time necessary.

Battery replacement
HD2013-DB uses an internal 3.6 V lithium‑thionyl chloride (Li-SOCl2) not
rechargeable battery, size C, with Molex 5264 2-pole connector. The charge
status of the battery is constantly monitored and displayed.
When the battery voltage drops below a certain value, the instrument
automatically turns off the backlit of the display, so as to minimize the battery
consumption and allow the instrument to continue to perform the measurement
functions. When the backlit is turned off, it is recommended to replace the
battery soon.
If the battery voltage drops further to a level that does not allow the correct
operation of the instrument, the message “CHANGE BATTERY NOW!” is
displayed; in such a case, the battery replacement is necessary.
The instrument is equipped with non-volatile memory: the data remain
stored even if the battery is discharged and disconnected.
1. To replace the battery, proceed as follows:
2. disconnect the instrument from the PC, if connected;
3. unscrew the four screws fixing the front cover;
4. remove the battery connector and take the battery out of its holder;
5. insert the new battery paying attention to the correct polarity (the connector
is provided with a protection device that prevents the reversal of polarity);
6. as an alternative to the lithium battery, if not available, three 1.5 V alkaline
batteries can be used, to be inserted in the batteries holder shown in figure
5. In such a case, connect the batteries holder connector to the battery
connector on the board of the instrument;
7. close the cover with the fixing screws; when closing, verify that the sealing
gasket is properly positioned; the screws must be securely fastened.
