1. Press MENU key, position the cursor onto EFF by using
the arrow keys (
,) and confirm with ENTER. The
display shows the screen here to the side, which contains
the global parameters of the system.

4. By using the arrow keys (
 , ) it is possible to set:
 Pmax  maximum rated power of PV installation
expressed in kW
 Range  coefficient of power variation with
temperature, characteristic parameter of PV modules
(typically in range: -0.3
 -0.5%/C)
 Noct  rated operating temperature of the cell,
characteristic parameter of PV modules (typically in
range: 42
 48°C)
 Te, Tc  setting of default values of environmental
and PV module temperatures. These values are taken
into consideration by the instrument only when probe
is not connected to unit SOLAR-02
 Corr. Type  Setting of the compensation
relationship on the calculation of Pdc power and the
maximization of DC performance (see § 5.2.3)
