19. Connect, if used, the auxiliary temperature probe (optional accessory) to the
AUX
input
of meter and on the rear of module, fixing it with adhesive tape
20. Connect the meter to the module/string under test as shown in Fig. 7a. In particular,
connect the negative output pole of module/string to P1, C1 input terminals and the
positive output pole of module/string to P2, C2 input terminals. In
Auto
activation mode
is recommended the use of KITKELVIN optional accessory

CAUTION
The method used by the instrument meter for output VDC and IDC
measurements of PV module/string is the “4-wire”. Therefore, it is possible to
use also test cables connected to P1, C1, P2, C2 inputs of different length
without performing any calibration of cable resistance.
It is recommended to
use cables with a §
4mm

21. After connection to the plant, the real time values of
parameters are shown by meter:
Vdc = DC output voltage of PV module/string
Irr = Irradiance value measured by sensor
Tc = Value of module temperature

CAUTION
At the press of
GO/STOP
key some different error messages can be
displayed by the meter (see § 6.4) and, due of this, the test cannot start.
Check and remove, if possible, this error message before start the test
22. Press
GO/STOP
key (in Manual activation mode) to start
the test. If none of the previous error messages are
detected, the message “
