5.3.18: Time Synchronization Alternatives
(See Communicator EXT User's Manual for details.)
IRIG-B:
All Nexus® 1262/1272 meters are equipped to use IRIG-B for Time Sychronization.
If IRIG-B is connected, this form of Time Synchronization takes precedence over the Internal
Clock. If the GPS Signal is lost, the Internal Clock takes over time keeping at the precise
moment the signal is lost.
Line Synchronization:
All Nexus® meters are equipped with Line Synchronization, which may be Enabled or
Disabled for use instead of IRIG-B. If Line Synchronization is Enabled and power is lost,
the Internal Clock takes over at the precise moment power is lost.
Internal Clock:
All Nexus® meters are equipped with Internal Clocks, which can be used if IRIG-B is not
connected and/or Line Sync is not Enabled. If either of the above Time Sync Tools fails, the
Internal Clock will take over at the precise moment the synchronization tool in use fails.
Time Setting Tools:
1. Tools, Set Device Time: For manual or PC Time Setting.
2. Script & Scheduler: Time Stamps Retrieved Logs and Data.
3. MV90: Can synchronize time on retrievals in the form of a Time Stamp.
Refer to the Communicator EXT User Manual (HHF Converter) for more MV-90
details.
