4. In order to guarantee the operator’s safety, disable the system being measured by
means of the switches/breakers upstream and downstream of the DC/AC converter
(inverter).
5. Bring PVCHECK and SOLAR-02 nearer (maximum distance of 1m between them). All
instruments must be switched on (see the User Manual of SOLAR-2 for further
details).
6. On PVCHECK, press the MENU key, select the function EFF and press ENTER; wait
for the two units to start communicating with each other. This condition is highlighted by
the contemporary presence of the following indicators:
 Symbol
steady (not flashing) on the display of PVCHECK
 Symbol
steady (not flashing) on the display of SOLAR-02
7. Connect the inputs P and N respectively to the positive and negative output of the
string, respecting the colours indicated in Fig. 4
8. Connect the output connector of the DC clamp to the IDC input.
CAUTION
BEFORE CONNECTING THE DC CLAMP TO THE CONDUCTORS
Switch on the clamp, check the LED indicating the status of the clamp’s
internal batteries (if present), select the correct range, press the ZERO key
on the DC clamp and check on the display of PVCHECK the actual zeroing
of the corresponding Idc value (values up to 0.02A are acceptable).
9. Connect the DC current clamp to the positive output conductor of the string,
respecting the direction of the arrow found on the clamp itself as indicated in
10. Fig. 4: Connection of instrument for efficiency measurement on a PV installation
11. . Position the clamp so that the jaw is not near the negative conductor.
12. The display shows the first screen which contains the
values of the output electrical parameters of the
module/string.
13. Before starting measuring, check for the presence of
symbol “
” steady on the display, which indicated a
correct RF connection with the remote unit SOLAR-02.
