cell until it rests on the tang found on the bracket so that the cell is perfectly parallel to
the surface of the module, then fix it with the relevant screws provided.

11. Connect the output of the cell corresponding to the type of module being tested to the
IRR. input of the instrument using the cable supplied with the cell, or to the
PYRA/CELL input of the remote unit SOLAR-02, if used (see Fig. 8 and Fig. 9)
12. If used, connect the temperature sensor to the TEMP input of the instrument and fasten
it to the backside of the module under a cell using some adhesive tape. As an
alternative, connect the sensor to the TEMP input of the remote unit SOLAR-02, if used
(see Fig. 8 and Fig. 9)
13. Connect the instrument to the module/string being tested and, if necessary, to the main
earth node of the system and to the earthed metal masses as shown in Fig. 8 and Fig.
9. In particular, connect the negative output pole of the module/string to terminal N and
the positive output pole of the module/string to terminal P.
CAUTION
In case the remote unit SOLAR-02 is used for measuring irradiance, make sure
that the RF communication with the master unit PVCHECK is always active
(symbol “
” on and steady on the display).
