Would ME kilowatt hour meter roll back to 0 after reaching maximum display capacity 9999 kWh?
After 9999.99 kWh, the counter will switch to 10.000 MWh. It will continue until it reaches 99999 MWh.
At this point, you must reset your "partial" counter, in order fo the recordings to continue.
The "total" counter cannot be reset and will remain at 99999 MWh unless the meter is sent back to the factory for a total energy reset.
