There is no option to set the Energy meter reset at 1 MWh.
There is no option to control the Energy readings.
Our meters will reset as per the below method for both Auto Scaling and Counter Mode.
1. The Reset for any Elmeasure Meter will occur at (999999 kvAH * MF )
2. MF is taken into consideration from calculation
3. kW calculation = (1.732*PT pri *CT pri)/1000
4. Example CT ratio(100/5) PT Ratio(415/415), will come in 0.1 MF table.
Hence, 999999 kvAH *0.1= 99999.9 kvAH.
It is reset accordingly.
99999.9 kvAH is 99.99 MVAH

If the Energy reading is in counter Mode then the readings will display as 99999.9kvAH
If the Energy reading is in Auto scale mode it will auto scale from VAH to kvAH and kvAH to MVAH.
Same will be applicable for WH readings also but the reset will be done based on kvAH value even if the values are not displaying in the meter.
Please note if the readings are in auto scale mode or counter mode in modbus register you will get the readings in WH or VAH only not in Kilo or Mega.
