6.2. I-V CURVE MEASUREMENT
The meter can perform I-V curve tests 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. Do
not measure voltages exceeding the limits prescribed by this manual
 The maximum current measured by the meter is 10A. 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
6. Press ENTER, by means of arrow keys (
,) select
item “Meas. Type ”
7. Using the
 key, select item “I-V Test” and confirm by
pressing ENTER

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
 Number  MAN or AUX mode of temp. measurement
 “ - - - “  AUX mode with no connected probe
 Module = type of selected module
 Temp = measurement mode of module temperature
