current clamp can be higher than of the instrument.
4.4.6 Synchronization (A 1378 - PV Remote unit)
The main purpose of the synchronization is:
-
to get correct values of temperature and irradiance for calculation of STC
measurement results.
-
to get values of cell temperature up to 15 minutes before the PV tests in order
to have an evidence that the measurement conditions were equilibrated during
the PV tests.
During the PV tests the displayed STC results are calculated on base of set or
measured environmental data in the instrument’s
Environmental menu
. These values
are not necessarily measured at the same time as other measurements.
