quantity of rain in mm in the last 10 minutes and in the last hour;
quantity of rain in mm in the last 4 and 24 hours;
quantity of rain in mm in the last 72 and 96 hours;
maximum rain intensity in mm/h in the last hour and in the last 24 hours;
quantity of rain in mm from the last counter reset
(partial rainfall)
;
date/time and battery voltage;
user code and serial number of the data logger.
The maximum rain intensity is calculated by dividing the relevant time (1 hour or 24 hours)
into 10 minutes intervals, and by calculating the quantity of rain that fell in each interval. The
maximum value of the calculated quantities is then multiplied by 6 to obtain the intensity in
mm/h.
The values of the quantity and intensity 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 maximum rain intensity exceeds 240 mm/h or
the rain quantity in 10 min, 1h, 4h, 24h, 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
/
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
/
button, then select ENTER button to exit.
Date/time, user code, resolution 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.
