Both Data and Event loggers can be read by means of either
FHview software or any DCS (Distributed Control System) linked
to the FH8400.
The reset of both loggers can be individually exercised by means
of the remote control device, the FHview software or DSC.
Remark : Both loggers operate according to the cyclic memory principle: when
all the available records are used, the most recent records erase the oldest
ones.
