6.7.2. Carrying out IVCK Tests without remote unit
CAUTION
 Check that no remote unit SOLAR03 is currently activated. Otherwise,
select “Unpair” to unpair the current active remote unit (see § 6.2).
 The maximum voltage between inputs P, N, E and C is 1500VDC. Do not
measure voltages exceeding the limits given in this manual.
 Do not perform test on PV modules/strings connected to DC/AC converter
 Standard IEC/EN62446 requires that measurements are performed string by
string. Even if the instrument is designed to manage inrush current for single
strings or strings connected in parallel, we recommend testing one string at
a time accordin
g
to the standard’s prescriptions.
1. Position the cursor onto IVCK by using the arrow keys
(,) and confirm with ENTER. The display shows the
screen to the side: The message “Remote U. not active”
indicates that no remote unit SOLAR03 is connected to
the instrument (see § 6.2). The following parameters are
shown:
 VTest  test voltage for insulation measurement
 ISO  minimum limit for insulation measurement
 RPE  maximum limit for continuity test
 ><  calibration resistance of cables for RPE test
 Values of volta

2. Use the arrow keys (,) to access the setting of
measurement parameters. The screen on the side
appears on the display. Use the arrow keys (, ) to set
the values. The following options are available:
 N. Mod x STR  set the number of modules of the
string in range: 1 ÷ 35
 N. Str in par.  Set the number of strings connected
in parallel in range: 1 ÷ 10
 Tol. Voc  set percentage tolerance for Voc
measurement in range: 1% ÷ 15% (typical 5%)
 Tol. Isc  set percentage tolerance for Isc
measurement in range: 1% ÷ 15% (typical 10%)
 Iso V. Test  set test voltage for insulation
measurement among the options: OFF
(measurement excluded), 250V, 500V, 1000V,
1500VDC
 Iso R.Lim  set the minimum reference threshold for
insulation measurement among the values:
0.05,0.10,0.23,0.25,0.50,1.00,50M
 RPE Lim  set the maximum limit for continuity test
among the values: OFF (measurement excluded),
1,2,3,4,5
 AVG values  the function “RESET” allows zeroing
the average values of Voc and Isc parameters before
starting a new measurement.
 AVG Voc, AVG Isc  average Voc and Isc values in
the 10 previously saved tests.
