6.2. I-V CURVE MEASUREMENT
The meter can perform I-V curve tests in automatic or manual activation mode by using
one of the herewith modes:
I-V curve test with Irr/Temp measurement directly performed by the instrument
I-V curve test with Irr/Temp measurement performed by use of remote unit SOLAR-02
For theoretical information on measurement see the § 11.1
6.2.1. I-V curve measurement by use of instrument
CAUTION
The maximum voltage among P1, P2, C1, and C2 inputs is 1000V DC (for I-
V400w and SOLAR I-Vw) or 1500VDC (for I-V500w and SOLAR I-Ve). Do
not measure voltages exceeding the limits prescribed by this manual
The maximum current measured by the meter is 15A. Do not perform test
on strings of PV modules in parallel with them
Do not perform test on PV modules or strings connected to DC/AC
converter
1. Turn on the meter by pressing
ON/OFF
key
2. Check that option NO relative to the selection of remote unit SOLAR-02 should be set
on the instrument (see § 5.1.4)
3. Check that the values set on the “Remote unit” section (see § 5.1.4) should be
consistent with the reference cell depending on the kind of module/string on test
4. Check that the value set on “Irradiance” section (see § 5.1.5) should be consistent with
the measurement to perform. It is suggested to perform the measurement with a
threshold
700 W/m
2
in compliance to the IEC/EN60891 guideline
5. Back to the main menu and select the “I-V” option

8. The instrument displays a screen similar to the one
reported here to the side, where:
Vdc = DC output voltage from module measured
between C1 and C2 inputs of meter
Irr = irradiance measured by supplied reference cell
Tc = temperature of module cell. The herewith options
are available for this field:
AUTO
automatic mode of temperature measurement
