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.
Synchronization (of time stamps) enables to later update the PV measured results with
environmental data that were measured simultaneously with the A 1378 PV Remote unit.
Stored STC values are then corrected accordingly.
Selecting this option will allow
synchronization of data between the
instrument and PV Remote unit.

Data to be synchronized:
TIME
Instrument’s time and date will be uploaded to the PV Remote unit.
RESULT
Values of measured environmental parameters will be downloaded to
the instrument. Saved STC results will be corrected accordingly.
