Essential information
Restoring the MID menu using the RESET menu
To change the set CT ratio and restore the MID settings menu shown at first power on EM530 MID models, enter the reset menu
and confirm "MID res".
Note: in MID models the reset can only be performed if the energy meter has not exceeded 1 kWh. In case of wrong settings, you
can then correct any CT current transformer setting errors (CT ratio), reactivating the MID programming menu.
Notes: if active energy has exceeded 1 kWh, the CT ratio cannot be changed.
