1INTRODUCTION

Fig.1.1 Data logger-indicator HD30.1 Fig.1.2 Measuring probe HD30.S1

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-card1or USB device).

The export format is compatible with the most common programs for data analysis and pro-

cessing. In addition to data storage, the software allows saving graph images.

The main quantities of photo-radiometric interest are directly calculated by the HD30.1

through the supplied software.

The analyzed spectral range varies according to the used measuring probe:

Visible Spectral Region (380nm-780nm) with the HD30.S1 probe,

Ultraviolet Spectral Region (220nm-400nm) with the HD30.S2 probe.

Measuring probes are interchangeable and calibrated (the calibration file is stored inside

each probe).

The probe HD30.S1 analyzes the visible spectral region (380nm-780nm) and calculates the

following photo-colorimetric quantities:

The probe HD30.S2 analyzes the ultraviolet spectral region (220nm-400nm) and calculates

the following radiometric quantities:

UVA Irradiance (W/m2), UVB Irradiance (W/m2) and UVC Irradiance (W/m2) (figure 1.4).

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 defor-

mation. Data concerning the calibration of the probe are stored in non-volatile memory and

are read by the indicator.

2INSTRUMENT COMMISSIONING

The instrument is delivered with disconnected battery pack inside the battery compartment

(figure 2.1).

Figure 2.1: Disconnected battery inside battery compartment.

To connect the battery pack, proceed as follows:

1- Remove the cover of the battery compartment (Figure 2.1)

2- Remove the battery pack from the housing (Figure 2.2)

Figure 2.2: Battery removed from housing.

3- Plug the battery pack connector to the HD30.1 device (figure 2.3).

Figure 2.3: Battery connector on HD30.1 device

4- Insert the batteries into the battery compartment (figure 2.4).

5- Close the cover.

The instrument works both with the battery and the external power supply (if power supply

is used, the battery must be installed into the instrument).

3MEASUREMENT GUIDE

1. When switching the instrument on, a yellow led (steady at first and then blinking) shows

that the instrument is starting. After 20 seconds, the instrument is operating and the start-

up screen appears if no probe is connected (fig 3.1)

Figure 3.1: Start-up screen with no probe connected.

all measurement functions in the screen are disabled.

appears in the header (blue bar on the top of the screen).

If a probe is already connected to the HD30.1 or is connected after the start-up, the splash

screen shows the enabled measurement options available for the connected probe:

Spectrum, photo-colour, radiometry and transmission for the HD30.S1 probe (figure 3.2),

Figure 3.2: Start-up screen with HD30.S1 probe connected.

Spectrum, radiometry and transmission for the HD30.S2 probe (figure 3.3)

Figure 3.3: Start-up screen with the HD30.S2 probe connected.

Connected will appear in the top bar to show that a probe is connected.

HD30.1 -9-V1.3

2. Connect the device for the data storage (otherwise data will be saved in the internal

memory of the instrument; the device where data are stored is shown in the blue bar on the

top), for more details see chapter “Handling and storing measurements”.

3. Select the type of analysis to be performed among the available ones:

3.1 SPECTRUM (HD30.S1 and HD30.S2 probes),

In this mode, the emission spectrum of the sources can be displayed or ambient light can

be measured in a simple and immediate manner with no further operations. The start-up

screen for this measurement will be displayed as shown on figure 3.4.

3.1.1. Select the operating mode of the instrument among the available four modes (SIN-

GLE, CONTINUE, MONITOR, LOGGING). By pressing the button two arrow sliders

are displayed; by pressing the button the operating mode changes as shown on fig-

ure 3.5.

3.1.1.1 SINGLE

Single measurement. The measurement is started by pressing . Once the measure-

ment is completed, the results are saved in a file with the file name automatically assigned

(the name of the saved file is like: spv-yymmddHHMMSS.txt for measurements performed

by the probe HD30.S1 and spu-yymmddHHMMSS.txt for measurements performed by the

probe HD30.S2).
