6.3.3. Fast check IVCK without irradiance measurement
CAUTION
 The maximum voltage among inputs P1, P2, C1 and C2 is 1000V DC. Do not
measure voltages exceeding the limits expressed in this manual.
 The maximum current allowable for the instrument is 10A. Do not effect tests
in parallel on FV module strings.
 Never effect tests on modules or FV strings connected to DC/AC converter.
1. Turn on the instrument pressing ON/OFF
2. Check that remote unit SOLAR-02 is not selected (see § 5.1.4– setting NO)
3. Check that the value of minimum irradiance set in the section “Irradiance” (see §5.1.5)
is equal to 0
4. Go back to main MENU and select “I-V”
5. Select “I-V” and press ENTER to enter the section of FV module performance
measurement. Generally when selecting I-V on general menu the instrument automatically
shows the last mode under use (I-V or IVCK).
6. In case the current mode is not IVCK, press ENTER,
select “Measurement ” by means of arrow keys
(
