6.3.2. Carrying out an IVCK quick test without measuring irradiance
CAUTION
 The maximum voltage between inputs P, N, E and C is 1000VDC. Do not
measure voltages exceeding the limits given in this manual
 Do not perform test on PV modules or strings connected to the DC/AC
converter
 The maximum current which can be measured by the instrument is 10A.
Before carrying out the measures of IVCK and Insulation in "STRING"
mode, always ensure that the instrument is connected to ONE STRING
and not more strings in parallel to avoid possible damage of it
1. Switch on the instrument by pressing the ON/OFF key.
2. Check that the remote unit SOLAR-02 is not selected (see § 5.1.4 – setting NO)
3. Check that the value of minimum irradiance set in section “Irradiance” (see § 5.1.5) is
equal to 0.
2. Position the cursor onto IVCK by using the arrow keys
(
,) and confirm with ENTER. The display shows the
screen to the side: The meaning of the parameters is the
following:
 Module  type of module being tested
 Vdc  value of output voltage from module/string
measured in real time
 Irr  value of irradiation measured in real time
 Tc  value of module temperature (see § 5.5.1)
 Voc, Isc  section with display of result OK/NO of
Voc and Isc measurement
 Ri()  the value in brackets may be NO/selected test
voltage (see § 5.5.1). The value of Ri indicates the
insulation resistance
 Rpe()  the value in brackets may be NO, Cal or
NoCal (see § 5.5.1). The value of Rpe indicates the
result of the continuity test.

3. Press the ENTER key, select “Settings” and confirm again with ENTER. Set the
instrument as indicated in § 5.5.1
4. If necessary, press the ENTER key, select “Reset Averages” and confirm again with
ENTER. If necessary, carry out this operation as indicated in § 6.3.4
5. If necessary, press the ENTER key, select “Leads calibration” and confirm again with
ENTER. If necessary, carry out this operation as indicated in § 6.5.2
6. 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. 6. 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.
