HD2402 - 5 - V1.3
1 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 CP24
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, from 1.0.1.0 version, and a PC; additionally,
stored data can be downloaded 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 pro-
grammed 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.
