HD2402 consists of a series of sensors used to cover the different portions of the spectrum and of a small LASER used to point the analysed source. The different sensors operate in the
following spectral ranges:
- Photometric sensor for the measurement of illuminance (luxmeter) in the spectral 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 downloaded and analysed 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 artificial 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.
