MID-protected setup parameters
This section describes the setup parameters that are permanently set at the factory and
cannot be modified, regardless of the lock or unlock settings.
The alarm / energy pulsing LED on the meter is permanently set for energy pulsing and
cannot be disabled or used for alarms. All other setup parameters for the energy
pulsing LED are also permanently set and cannot be modified.
NOTE: The pulses per kWh reflect uncompensated values only. This means that the
PT and CT values are ignored and the pulses represent the raw energy calculated from
the metering inputs.
Lock-protected setup parameters
This section lists the meter’s lock-protected setup parameters for MID compliance. After
the meter is locked, these setup parameters are protected and cannot be edited.
The setup parameters can be accessed from the maintenance menu screen. Use the
front panel buttons to navigate to the Maint > Setup menu.
