8. DESCRIPTION OF THE MENUS
When the instrument is switched on and the main screen is displayed, the bottom right box contains the
"FUNCTIONS MENU" with the main options. Each menu option selected gives access to one of the specific
functions described below.
Emissivity:
8.1 USING THE ALPHANUMERIC KEYPAD
Proceed as follows to select the options of the "FUNCTIONS MENU":
♦
Place the yellow cursor on the desired option using the • or •arrow key; or •arrow key;
♦
Press the ENTER button to confirm each selection;
♦
Then enter the data using the alphanumeric keys, bearing in mind that by continuing to press
the same button you select the corresponding letters and figures;
♦
Press ENTER again to validate your entry.
8.2 SITE MENU
8.2.1 NEW SITE DATA
This function is used to adjust the parameters of the installation being checked, in addition to the register of
data concerning the sites, to print the certification document.
You can configure up to 20 sites in the memory of the instrument, each of which can acquire a maximum of
12 measurement reports (certifications).
REMARK: since the data concerning the POWER of the site, the SENSITIVITY of the pyranometer, and the
NOCT and GAMMA parameters are used for the efficiency calculations, make sure to enter the correct
values to avoid vitiating the calculations.
♦
Power of the site [kW]: indicates the theoretical power of the site;
♦
NOCT [°C]: nominal operating temperature of the cel l (data provided by the manufacturer of
the panels);
♦
GAMMA g [%/°C]: power vs. temperature coefficient o f the PV module (value entered between
0.01 and 0.99) (data provided by the manufacturer of the panels)
REMARK: enter the unsigned numerical value “+” or “-”;
♦
Name: indicates the name of the site;
♦
Address (street and number), postal code and Town: indicate the address of the site;
♦
Code: indicates the customer's tax file number;
♦
Select CONFIRMATION and wait for the data entered to be recorded.
REMARK: the data entered are recorded only if the power of the site, NOCT, and GAMMA have been
entered correctly.
8.2.2 A LOOK AT THE THEORY
One characteristic of the photovoltaic panels used, the parameter
γγγγ
(gamma), is generally indicated by the
manufacturer of the panels. For modules made of crystalline silicon, it is generally 0.4-0.5%°C (to en ter the
value of g, refer to the description of the NEW SITE DATA MENU).
The NOCT parameter is characteristic of the photovoltaic panels used. It too is indicated by the
manufacturer of the panels. For modules made of crystalline silicon, it is generally between 40°C and 50°C.
Temperatures Tamb and Tcel are used in the calculations by the GREEN TEST FTV 100 and are measured
by a Pt100 temperature probe.
