Press the MENU key until the “>>>_LOG_DUMP_or_ERAS” item is displayed and then press on
the LOG key: the transfer of the data contained in the instrument internal memory via the serial port
is started.
Please, see the paragraph dedicated to data transfer on page 25.
SERIAL key - only HD2102.1
SERIAL/EraseLOG key - only HD2102.2
In measurement mode, this function starts and stops the data transfer to the RS232C serial output.
According to the settings entered in the Print and log interval menu item, a single sample can be
printed if Print and log interval=0 or a continuous indefinite printing of the measured data can be
set up if Print and log interval=1…3600 s.
The printing operation is accompanied by the display of the RS232 symbol and the blinking of the
battery symbol; when using an external power supply the battery symbol does not appear.
Press SERIAL to end the continuous printing.
The variable appearing on the display upon pressing the SERIAL key is printed: the variable
associated with the probe connected to the instrument, with its relevant unit of measurement or the
integral Q(t).
With the combined probe LP 471 P-A and LP 471 A-UVeff each sample consists of three measures
(illuminance, UVA irradiance and the ratio of the two measurements with the first probe; total
effective irradiance, the effective irradiance in the range UV-CB and the UVA irradiance with the
second probe).
Before starting the printing with SERIAL, set the baud rate. To do so, select the Baud Rate menu
item and select the maximum value equal to 38400 baud by using the arrows. Confirm with
ENTER.
The DeltaLog9 software for PC will automatically set the baud rate value during connection. If you
are using a different program than DeltaLog9, be sure the baud rate is the same for both the
instrument and the PC: the communication will only work in this way.

Erase memory - only HD2102.2
Press the MENU key until the “>>>_LOG_DUMP_or_ERAS” item is displayed and then press on
the SERIAL/EraseLOG key: this clears permanently all the data contained in the instrument’s
memory.
