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
Fig. 7a: Instrument connection to module/string FV
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
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 "Measuring..." is shown on the
display for some seconds, depending on the level of
power during test.
