Time synchronization

Your meter’s clock controls the timing of metering parameters, such as demand intervals or power quality measurement aggregation over time intervals.

Adjustments to the clock are made by synchronizing the meter’s time with another time source, determined by the Time Sync Source. Time synchronization messages can be automatically generated and sent to your meter from your energy management system software or other time sources such as an SNTP/NTP server, PTP Master or GPS receiver. You can also manually trigger a time synchronization message from your energy management system or configuration software.

NOTE: To help maintain data integrity, some energy management systems impose a blackout rule where time synchronization messages near energy interval boundaries are ignored.
