1. INTRODUCTION Fig.1.1 Data logger-indicator HD30.1 Fig.1.2 Measuring probe HD30.S1 Measuring probe HD30.S2 The data logger-indicator, running Linux operating system, handles data processing and management. It has a large color touchscreen display, ensuring easy execution, display and logging of measurements. Spectra and derived quantities can be saved both into internal (150MB) and external memory (micro SD-card1 or USB device).
The probe HD30.S1 analyzes the visible spectral region (380nm-780nm) and calculates the following photo-colorimetric quantities: Illuminance [lux], Correlated Color Temperature CCT [K], Trichromatic Coordinates [x,y] (CIE 1931) or [u’,v’](CIE1978), CRI (color rendering index, R1…R14, Ra) , PAR [µmolphot/sm2] (fig. 1.3) Figure 1.3 The probe HD30.
Figure 1.4 Both sensors have a view of the input equipped with a new generation diffuser which allows optimizing the response according to the cosine law and not introducing any spectral deformation. Data concerning the calibration of the probe are stored in non-volatile memory and are read by the indicator.

7. EXPORTING MEASUREMENTS The instrument allows you to export the performed measurements to a pdf file; besides the pdf file, a text file is generated where the wavelength in 1-nm steps and the measured spectral irradiance are shown respectively in two columns (in the case of transmission measurements, the measured spectral transmission is shown). The generated pdf file shows the spectral irradiance in 1 nanometer steps and the processed data.
Data export key Fig. 7.2: Exporting a previously performed measurement If the measurement is displayed in Spectrum mode , exported data are only those related to spectral irradiance (the spectrum image appears in the exported file) and the file is saved with the following name: rsp-yymmddHHMMSS.pdf the text file containing only spectral irradiance data is saved with the name : r1n_ yymmddHHMMSS.
If the measurement is displayed in radiometry mode , the exported data are spectral irradiance and all the calculated radiometric data (the spectrum image appears in the exported file). The file is saved with the following name: rrd-yymmddHHMMSS.pdf the text file containing only spectral irradiance data is saved with the name: r1n-yymmddHHMMSS.
