6.3. RPE – CONTINUITY MEASUREMENT ON PV MODULES/STRINGS/FIELDS
The purpose of this measurement is performing a continuity test of the protective and
equipotential conductors (e.g.: from rod to earth and connected foreign earth) and earth
rods of SPDs on PV installations. The test must be carried out using a test current >
200mA in compliance with standards IEC/EN62446-1 and IEC/EN61557-4.
CAUTION
We recommend a preliminary check of correct functioning of the instrument
before carrying out a measurement by shorting input terminals E and C,
checking an almost zero continuity value and an out-of-scale value with
terminals E and C open
