Protected setup parameters and functions

Your meter has features and settings that cannot be changed while the meter is revenue-locked.

In order to prevent modifications to revenue-related settings and data on your meter, some of the features and parameters on your meter cannot be edited once the meter is revenue-locked.

Protected setup parameters

Settings	Protected status	Description
Power system settings *	Yes	You cannot change any power system settings while the meter is locked (for example, power system type, VT and CT connections, VT and CT primary and secondary values, system frequency and phase rotation)
Meter label	Yes	You cannot change the meter label while the meter is locked
Meter date	Yes	You cannot change the meter’s date while the meter is locked
Energy pulsing	PM5561 / PM5661 / PM5761 : See description PM5562 /PM5562MC : Not locked	The alarm / energy pulsing LED on the PM5561 / PM5661 / PM5761 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. The settings are fixed at: Mode (Control) = Energy (energy pulsing) Pulses per k_h (Pulse Rate) = 10,000 (pulses per kWh) 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. Channel (Parameter) = Active Energy Del+Rec
Multi-tariff and input metering settings	Yes	You cannot change multi-tariff mode or settings while the meter is locked. PM5561 / PM5661 / PM5761 : You can only configure a subset of input metering settings when the meter is locked (channel label and demand code cannot be configured). PM5562 /PM5562MC : You cannot configure input metering settings when the meter is locked.
