6.2.2.2. I-V curve test by remote unit SOLAR-02 in synchro recording
This mode, which consists in an independent recording of the irradiance and temperature
parameters by the remote unit SOLAR-02, permits to perform I-V curve test also with wide
distance between the instrument and SOLAR-02 without any connection between them.
On the other hand, due to the impossibility for the meter to have immediately the values of
irradiance/temperature, it is necessary wait the transfer of data from remote unit SOLAR-
02 to main unit in order to have all the available results.
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 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
4. Back to the main menu and select the “I-V” measurement mode
5. Press ENTER, by means of arrow keys (
,) select
item “Meas. Type ”
6. Using the
 key, select item “I-V Test” and confirm by
pressing ENTER

7. Switch on the remote unit SOLAR-02 and wait that “Radio connection active” message
is displayed
8. Check the status of internal batteries of SOLAR-02 (the “ ” symbol should be not
displayed)
9. Check that the values of sensitivity and temperature coefficient set on the SOLAR-02
section should be consistent with the reference cell depending on the kind of
module/string on test (see user manual of SOLAR-02)
