PVCHECK 29

The overall value of the results:
o
OK: if all results under OPC are OK,
o
NO if one of the results under OPC is NO
17. Press the

key to go back to the previous screen.
18. Press the SAVE
key to store the test result in the instrument’s memory (see § 7.2) or the
ESC/MENU key to exit the screen without saving and go back to the main measuring screen.
CAUTION
The average values of Voc and Isc are displayed in the results’ page. These values
include the average values of Voc and Isc under OPC conditions calculated as mean of
the last 10 tests previously saved. If the user has carried out and saved a number of tests
<10 or reset the average values (see § 6.3.4) the average value displayed during test
N+1 will be calculated on the available N values.
6.3.3. Carrying out an IVCK quick test and 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. Irradiance measurement is carried out in one of the following modes:

Measurement by reference cell directly connected to PVCHECK

Measurement by reference cell connected to a connected SOLAR-02 unit RF with
PVCHECK
3. Check that the settings of remote unit SOLAR-02 are consistent with the type of
measurement to be carried out (see § 5.1.4).
4. Check the minimum irradiance value set (see § 5.1.5).
5. 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.
6. Press the ENTER
key, select “
Settings
” and confirm again with
ENTER . Set the instrument as
indicated in § 5.5.1
7. If necessary, press the ENTER
key, select “
Average Reset
” and confirm again with
ENTER .
Carry out this operation as indicated in § 6.3.4
8. If necessary, press the ENTER
key, select “
Cable calibration
” and confirm again with
ENTER .
Carry out this operation as indicated in § 6.5.2
