INTRODUCTION
HD2402
is a portable datalogger photo-radiometer for the measurement of
non-
coherent optical radiations in accordance with 2006/25/CE European direc-
tive and legislative decree No 81 of 9 April 2008.
The instrument consists of a series of sensors used to cover the different portions of
the spectrum and of a small LASER used to point the analyzed source.
The different sensors operate in the following spectral ranges:
•
Photometric sensor for the measurement of illuminance (luxmeter) in the spec-
tral range 380÷780 nm.
•
Radiometric sensor for UV band (220÷400 nm) with spectral weight factor S(
λ
).
•
Radiometric sensor for UVA band (315÷400 nm).
•
Radiometric sensor for 400÷700 nm (blue) band with spectral weight factor
B(
λ
).
•
Radiometric sensor for IR band (700÷1300 nm) with spectral weight factor
R(
λ
).
•
Thermopile sensor for the measurement of infrared radiance, 400÷2800 nm
spectral range.
HD2402
unit can be powered through connection to the USB port of a PC, or through
an external power supply unit provided with an USB port (
SWD05
code). The
CP24H
connection cable is provided with a M12 connector on the instrument side and with an
A-type USB connector on the PC side or on the
SWD05
power supply unit side.
HD2402
can be configured (calendar, date, time, start time and logging time) by
means of
DeltaLog13 software
and a PC; additionally, stored data can be down-
loaded and analyzed and new data can be acquired in real time. Once configured, the
datalogger can be disconnected from the PC and connected to the power supply unit
for data acquisition and storage according to the programmed settings.
The unit is provided with a button for data storage manual start/stop when the unit is
not connected to a PC.
A LED indicator on the back of the unit shows the instrument’s acquisition state.
The legislative decree No 81/08, paragraph 5, establishes the measurement of artifi-
cial optical radiations (AOR) produced by incoherent light and coherent light (LASER).
HD2402 unit can perform characterization of incoherent sources and in this manual,
unless otherwise specified, reference will be made only to this kind of sources.
Attachment No 37 of L.D. 81/08 provides the formulas (Table 1) to determine the bio-
physically-relevant limit values of exposure to optical radiations.
