Issue
PM5000 energy rollover

Product Line
PM5000 Series Meters

Environment
PM5000

Cause
Limit for maximum energy value

Resolution
The energy value is stored in a signed 64 bit integer register (INT64).
Therefore, the PM5000 series meter accumulated energy value will reset after +/- (2⁶³ -1) Wh of energy. (Approximately 9.223 x10^18)
(this value can also be gotten by halving the value of a 64 bit register:  +/- [((2⁶⁴) -1) / 2]
