Time Synchronization
Time synchronization lets you synchronize the internal clocks of all networked
meters and devices. Once synchronized, all data logs have timestamps that are
relative to a uniform time base. This allows you to achieve precise sequence-of-
events and power quality analyses. To synchronize clocks, use ACCESS software
to broadcast time signals across the network.
