6.2.2. I-V curve measurement by use of remote unit SOLAR-02
The I-V curve test with Irr/Temp measurement by use of remote unit SOLAR-02 can be
performed in one of the herewith mode:
 Remote unit SOLAR-02 in RF connection with main unit
 Remote unit SOLAR-02 in synchro recording (no RF connection with main unit)
6.2.2.1. I-V curve test by remote unit SOLAR-02 in RF connection
This mode is possible ONLY if the distance between the main unit and the remote unit
SOLAR-02 can establish always a stable RF connection. This distance limit is influenced
by obstacles, air humidity, etc., so it is considered valid about some meters.
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 YES 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
