Retrieving Interval Data
The MD-xxHD meter maintains an internal log of the energy data (Net kWh) for each channel in the
meter. This log is updated every 15 minutes and is always active. The meter stores 63
days’ worth of 15-
minute data in its memory. This data can be retrieved by users looking to restore gaps in data collection
where RTUs may have been offline or communication has been interrupted. The Interval Data Recording
(IDR) is assessed through ViewPoint HD in the Advanced menu.
