When iEM3200 auto ranges from kWh to MWh?

How can we help you today?

Issue:
My customer has a iEM3200 and seeks clarification on when the meter auto ranges from kWh to MWh.
The data sheet states that the display will show 99999999.9 kWh/MWh
My customer wants to know at what point will it auto range.
At what point will it change?
Will it change at 99999999.9 or 9999999.99 or 999999.999?

Answer:
IEM3200 can display 99999999.9kWh. Once its past the value, it will roll over to MWh. So it will change at 99999999.9kWh.
